With the help of Germán and Oliver setup the [[D3D Australia]].

This is my very first 3D print. It is a OSE test cube :). Look how cute and adorable it is:

[[File:test-cube-ruslan.jpg]]

I need to make some very small adjustments of the z axis and buy some PLA filament.

= Sun Jan 1, 2019 =
Tried to connect D3D Australia to computer:

* Cura does not see the printer.
* slic3r crashes with "** (slic3r.pl:8312): CRITICAL **: 11:58:45.761: murrine_style_draw_box: assertion 'width >= -1' failed" as soon as I try to test the printer.

I tried to connect manually to usb device /dev/ttyACM0. It worked only with superuser permissions. I checked permissions of the device

ls -l /dev/ttyA*

crw-rw---- 1 root dialout 166, 0 Jan 1 12:32 /dev/ttyACM0

then I checked if I am in the dialout group

id -Gn ruslan

I was not. I added my self to the group

sudo usermod -a -G dialout ruslan

Reconnect. And it still does not work. But after reboot, the connection to/dev/ttyACM0 works. And cura can see the printer!

What is the orientation of the axis? [https://wiki.opensourceecology.org/wiki/D3D_Controller#Wiring] does not answer the question: Where the positive z axis points to?
I got confused by the motion of the z-axis. When I send positive z value, the printing bet moves down. This is the correct behavior, because if the bet moves down, then the printing head moves up.

Found out better port representation for pipe fittings. Add port documentation to [https://wiki.opensourceecology.de/OSE_Piping_Workbench_Ports German OSE Wiki] because it supports mathematical formulas.

= Sun Nov 20, 2018 =
Started to implement new positioning for pipe fitting in OSE-piping-workbench.

= Sat Nov 19, 2018 =

I bought some missing parts for Germáns printer: a bearing and two M6 bolts. I still need an Australia-Europe adaptor to switch on the printer.

==DONE==
* published [https://gitlab.com/rkrenzler/3d-printer-germany 3D printer CAD] files

= Sat Nov 10, 2018 =
The FreeCAD user Kunda1 helped me to setup FreeCAD debugger! [[Debugging in FreeCAD]]

Ask: by dev meeting:
* Is a BOM integration in FreeCAD interesting to us?

Like [https://github.com/openscopeproject/InteractiveHtmlBom] or [https://github.com/SchrodingersGat/KiBoM].

See [https://forum.freecadweb.org/viewtopic.php?f=8&t=31344&p=268109#p268109 FreeCAD forum].

=Sun Nov 4, 2018=
I started to learn physics to calculate mechanical properties of a 3D-printer. My motivations are

* Creating a decision support systems, which can suggest stepper dimensions.
* Technical efficiency through optimizations.
* Efficient use of human resources. Do important work which only view people can do.
* [[Mathematics of Classical Mechanics|Fun and Education]].

== BLOCKS ==
No support for mathematical formulas in the wiki :(.

=Sun October 30, 2018=
I am back. I am writing this from my mud hut, not :). There are couple of things to do:
#improve piping workbench - integration with Flamingo workbench; finish and forget.
#publish 3D printer CAD files
#repair Germán's 3D printer
#Improve the axis - automated generation of axes
#complete the OSE part library workbench
#learn cool physics for 3D printer calculations: Lagrangian mechanics.

==DONE==
* I tried to find out how to debug FreeCAD. It just does not work :(. FreeCAD crashed. How I suppose to teach someone to program under these conditions?
* I puslished ose-piping-library -- the prediscessor of ose-piping workbench -- under the CC0 license (Public Domain).

=Sun August 19, 2018=
Tried to setup Germán's D3D printer with Germáns help. Worked well. The D3d seems mostly to survive transportation well. But view parts are broken or missing.
Broken:

* One peg which holds pegs.
* A lot of magnets felt off.
* Y Stop felt off [[File:End_stop_y.jpg|100px|]].

Missing:
* One bolt which keeps a bearings in one end of the universal axis.
* One bolt which to fix heated bed
* One bearing.

I need to buy missing parts and then continue with assembly.

=Sun August 5, 2018=
* Improved CSV documentation [[OSE_Piping_Workbench#Customization|customization]] of OSE Pipe Workbench.

=Sat August 4, 2018=
* Worked on better part placement in [[OSE Piping Workbench]]. The prediction of correct side does not work in flamingo.

= Sun 1. July 2018 =
Partially made [[D3D_v18.06.12#CAD]]. Took the frame and axis from Oliver. Add Stepper and missing axis parts. Spent a lot of time trying to rotate stuff in FreeCAD. It is very frustrated or I am missing some FreeCAD tricks.

= Sun 25. June 2018 =
Follow the video istructions from Marcin [https://www.youtube.com/watch?v=yXPpK2lu32k]

= Sun 24. June 2018 =
Started [[D3D_v18.06.12]] Printer.

= Sat 10. June 2018 =

Worked on OSE-piping workbench. Rename modules. Made them better fit to FreeCAD naming style.
Adjust D3D-printer workbench.

= Sat 09. June 2018 =

Worked on OSE-piping workbenched. Migration of elbows to Flamingo style finished. I added bend angle to the sweep elbow.
== TODO ==
Rename Modules to prevent conflicts with other workbenches.

= Thu 07. June 2018 =
I met Michel from [https://collectiveopensourcehardware.github.io/about/ cos(h)] group -- a student group from Hamburg University of Applied Science (HAW Hamburg). I already met this group multiple times before -- they are nice and professional. One of their projects is [http://libre.solar/ Libre Solar]. They build [https://collectiveopensourcehardware.github.io/hardware/solarbox_intro/ Solar Box] - a device which you plug between solar panels and electrical devices. The Solar Box optimizes power conversion and stores excessive energy in batteries.

The cos(h)-team goes beyond just Open Hardware -- they make good assembly instructions [https://collectiveopensourcehardware.github.io/education/ https://collectiveopensourcehardware.github.io/education/]!

It is possible to work together on the 3D-Printer!

= Sat 03. June 2018 =
Worked on PVC-pipig work bench. Oriented elbow as in flamingo.

Add a video tutorial, how to connect two pipes with an elbow. The elbow geometry can be changed.

<html>
<iframe width="560" height="315" src="https://www.youtube.com/embed/Mv9AxmRe14U" frameborder="0" allow="autoplay; encrypted-media" allowfullscreen></iframe>
</html>

== Problems ==
The channel in the middle part of an elbow is not displayed correctly :(. You can see it, if you make the elbow transparent.

= Sat 02. June 2018 =

Access to https://wiki.opensourceecology.org forbidden. Why?

Today I worked on PVC-piping workbench. I changed orientation of the parts and solid elbow from x-z plane with to x-y plane with symmetry to x-y bisectrix. This corresponds to flamingo elbow orientation.

One freecad user asked me to write a ''howto to create fitting'' [https://forum.freecadweb.org/viewtopic.php?f=8&t=27641&p=237023#p236929]. I will do it.

== TODO ==
* position and rotate my flamingo elbow the same way as flamingo-flamingo elbow does. (x-y plane with x-y bisectrix symmetery instead of x-z plane).

= Tue 29. May 2018 =

Jen found a useful link to [http://codes.iapmo.org/home.aspx?code=UPC Uniform Plumbing Code].

= Sat 12. May 2018 =

Start to create new workbench. It is easy to work directly with FreeCAD Module directory.
<pre>
cd ~/.FreeCAD/Mod
</pre>

== Setup repository ==
I use Stephen's [https://github.com/skaiser/FreeCAD_Workbench_Starter FreeCAD_Workbench_Starter].

I could not fork it, because I already fork it for [https://github.com/rkrenzler/ose-piping-workbench ose-piping-workbench]. Instead I made clone of it with a new name.

<pre>
git clone https://github.com/skaiser/FreeCAD_Workbench_Starter ose-part-library-workbench
cd ose-part-library-workbench
</pre>

I create a github remote directory where I can make my code accessible for the public.

The cloned repository is still bound to Stephen's repository. I want to bound it to my github repository. I rename the Stephen's ''origin'' as "upstream".

<pre>
git remote rename origin upstream
</pre>

and add my new git-hub repository as an ''origin''.
<pre>
git remote add origin https://github.com/rkrenzler/ose-part-library-workbench.git
</pre>

Now I push my recent created repository to my github repository

<pre>
git push -u origin master
</pre>

== Adjust files ==
* edit ''README.md''. Add new project description.
* Rename OSE_ExampleWorkbench to OSE_PartLibraryWorkbench in InitGui.py, adjust text.

<pre>

class OSE_PartLibraryWorkbench (Workbench):

MenuText = "OSE Part Library Workbench"
ToolTip = "Add parts from Open Source Ecology project"
#Icon = """paste here the contents of a 16x16 xpm icon"""

</pre>

edit the last line in InitGui.py too
<pre>
Gui.addWorkbench(OSE_PartLibraryWorkbench())
</pre>

rename OSEBase.py and rename OSE_CommandButton.py to something else to prevent conflicts with other workbenches. Adjust dependent files.

= Thu 10. May 2018 =
== Looked for standard ==

[https://www.astm.org/Standards/plastic-pipe-standards.html]
* A brief list of all dimenensions and their minning is here [https://www.astm.org/Standards/D2749.htm| ASTM D2749 - 13].
* More detailed list: ASTM D3311
What we do not need:
* D 2665 – 0: Designation: D 2665 – 04, ''Standard Specification for Poly(Vinyl Chloride) (PVC) Plastic Drain, Waste, and Vent Pipe and Fittings'', This standard is more focused on material and mechanical properties of pipes and fittings.

== Thoughts ==
* Support Open Source standards.
* Use metric system.

* Select code style and reformat code.

= Tue 3. April 2018 =
Dev Team Meeting [[Development_Team_Log]].

= Mon 2. April 2018 =
Rewritten [[OSE_piping_workbench#Elbow]]. Now it uses PThk (pipe thicnness) instead of PID (pipe inner diameter). It does not create 2D drafts any more, this simplified the composed (non-solid) version of the elbow. The Flamingo version is has now the same orientation as the normal version.

If you update OSE-piping-workbench from github also update D3D-Printer-Workbench.

OSE-piping workbench is experimental. Especially the Flamingo support. Possible I will change some things in the future.
== Problems ==
Tried to create a discussion with Disqus -- it is not possible. Disqus is user unfriendly and useless.

= Sat Mar 24. 2018 =
Continue to integrate Flamingo [[OSE piping workbench]]. Add Flamingo iplimentations to [[OSE piping workbench#Pipes] and [[OSE piping workbench#Elbows]]. You can now change their parameters dynamically.

== DONE ==
* Flamingo integrated into the pipe GUI.
* Flamingo integrated into the elbow GUI. Oddtopus - the developer of Flamingo - provided code and documentation.

= Fri Mar 23. 2018 =
Worked on [[OSE piping workbench]]. Started Flamingo integration to the pipe interface. The developer - Oddtopus - of Flamingo
oddtpus made a FreeCAD orum entry [https://forum.freecadweb.org/viewtopic.php?f=8&t=27641&sid=0f829d3bd056ec5add5407879796451a] and already contribute some code and documentation.

Visited [http://openecolab.de/oe-rahden.html OpenEcoLab and organic mushroom farm] of [[User:Oliver]]. Saw many tools made with [https://wiki.opensourceecology.de/Universal_Prototyping_Kit T-slot profile] the frame is more expensive than PVC but the aluminum frame is easier to transport and looks better and more robuster. Ate mushrooms 😋.

= Mon Mar 13. 2018 =

AAAAAAAAhhh. I got confused by the CST-USA time. Went to the meeting 1 hour later 😭.

= Mon Mar 12. 2018 =
Programming OSE piping workbench.

== Problem and solution ==
* There are also not much examples of pivy to understand how it woks. Coin website suggests to use documentation of open inventor API. For main idea see [http://www-evasion.imag.fr/Membres/Francois.Faure/doc/inventorMentor/sgi_html/ Inventor Mentor Book]
* dir(obj) does not display all attributes. Try to guess them from C++ API in ''Open Inventor C++ Reference Manual''. If you need to get a possible list of arguments you can call something like ''obj.translation.setValue(invalid data)'' to provoke an error message with some suggestions for arguments.
* I do not know how to make hideable ports. They are always displayed.

How to test coin code:

from pivy import coin
sg = FreeCADGui.ActiveDocument.ActiveView.getSceneGraph()
sep = coin.SoSeparator() # add other objects here
cyl = coin.SoCylinder()
sep.addChild(cyl)
sg.addChild(sep)
# Remove object from the view.
sg.removeChild(sep)

== Some thoughts ==
* 3D printer with PVC frame has disadvantages: once built, the frame cannot be disassembled;
:*It can be taken apart with heat gun. Best way is to cut near the corner, heat the pipe, and then take it out. See [[Removing PVC Joints]].
* what about all PVC waste;
* Teach to build. What about basic didactic skills? What to do if something will go wrong: accident, missing part, broken part, participants with not sufficient fine motor skills.

= Sat Mar 11. 2018 =
Try to create create pipes as a pipe as [https://www.freecadweb.org/wiki/Scripted_objects Scripted Object] with special positioning and rotation commands.
== Done ==
* Pipe as a ''Part::FeaturePython''. Be careful, in Freecad [https://www.freecadweb.org/wiki/Scripted_objects examples] there are ''Part::FeaturePython'' and ''App::FeaturePython'' are used. They are not the same.

== Problems (and solutions) ==
[https://www.freecadweb.org/wiki/Pivy] points to the wrong documentation. It is [https://bitbucket.org/Coin3D/coin/wiki/Documentation here]

== To do ==
* Different view with drag and rotation points.
* Command for moving parts around.

= Tue Mar 06. 2018 =
It looks like T-Profile version for the 3D printer is not much more expensive than the PVC version.

The development of a pipe frame macro was a failure [[How piping macros are made#Failure analysis]]. [https://www.freecadweb.org/wiki/Sandbox:Flamingo|Flamingo]. Developer meeting.

= Sun Feb 11. 2018 =

[[How piping macros are made]]. Added Macro to create a complete frame box from pipe and corners [[File:create-frame-box.FCMacro]]. It is not possible now to select pipe and corner names from a list. The user must put the part names into corresponding edit fields.

One needs recent [[File:pipe.csv]] and [[File:outer-corner.csv]] to use [[File:create-frame-box.FCMacro]].

=== Problems ===
I should definitively make a pipe workbench. The customized macros for complex part like a frame box costs too much time.

= Sat Feb 10. 2018 =

Formulas to translate Formfit dimensions at [https://assets.formufit.com/tsd/TSD-F0013WE.pdf] to Macro dimensions. We use lower case letters for Formfit dimensions, then it holds:

H = a - g/2

M = g

G = H-e = a - g/2 -e

POD = d ( Note, the dimension "d" of a 1" corner does not correspond to the outside diameter of a NPS 1" pipe)

PID is unknow, just take a value from the NPS pipe dimensions.

* Added corner dimensions from Formufit. The dimension G from Aetna Plastics for the 1" -corner Part Number 413-015 seems to be wrong. 3/16 is too small. I replaced it by 13/16. On the OSE wiki, the dimensions are now from Formufit.
* Fixed pipe names in [[File:Pipe.csv]] from 'NPS xy"' to 'NPS xy in'. FreeCAD cannot edit names of the created parts if they contain '"' symbol.

=== Problems ===

* To champfer edges of the corners is easy to do manually in FreeCAD but I did not find a way to do it programmatically from a macro.

* Assembly2 stops working after I used about 4 circular constraints.

= Fri Feb 09, 2018 =
Disqus - https://disqus.com/. Developer Meeting. Started to devolop pipe corners for 3D printer frame. Next 12 weeks:

Add dimensions check for [[File:Create-tee.fcmacro]]. Developer Meeting.

= Sun Feb 04, 2018 =
Updated [[File:create-pipe.fcmacro]]. Now the macro is customizable and uses [[File:pipe.csv]] like the other macros. Updated [[PVC Pipe and Fittings Library#Pipes]].

Created instruction video [https://youtu.be/9FlW4C4nk68] which explains how to install pipe macros.

Updated ellbow macros [[File:create-elbow-90.FCMacro]] and [[File:create-elbow-alpha.FCMacro]]. They hide now not more auxiliary sketches.

=== Problems ===
* Why the wiki always shows a strange screenshot of the pipe: [http://opensourceecology.org/wiki/File:Pvc-pipe-cad-screenshot.png] even if I tried to updated it multiple times?

=== Problems Solved ===
From Sat Feb 03, 2018.
* The bushing uses the outer pipe dimensions for the larger dimensions of the bushing.

= Sat Feb 03, 2018 =
Created [[File:Create-bushing.FCMacro]], added bushing dimensions from Aetna Plastics to [https://github.com/rkrenzler/ose-piping-library-data https://github.com/rkrenzler/ose-piping-library-data], created [[PVC Pipe and Fittings Library#Bushings]].

=== Problems ===
* '''SOLVED''' (See the entry on Sunday, next day) There are some inconsistent dimensions for the shape of bushings which I use. See the picture below:

[[File:bushing-dimensions.png]]

If dimension "PID" is smaller than "POD1" then this bushing shape is not possible. This problem occurs for example in a 3/8"->"1/4" bushing with the part name "437-052" from Aetna Plastics.

* There are no dimensions or shape for the hexagonal or octagonal part of the fitting. There are also no dimension with the conical inner socket part. I just invented these dimensions and they should be considered to be symbolic and do not resemble the real parts.

= Fri Feb 02, 2018 =
Improved in [[File:Create-cross.FCMacro]] added cross dimensions from Aetna Plastics to [https://github.com/rkrenzler/ose-piping-library-data https://github.com/rkrenzler/ose-piping-library-data].

[[PVC Pipe and Fittings Library#Cross]] section. Update [[File:pvc-coupling-test.fcstd]] (it was created by a buggy create-coupling macro).

= Sat Jan 27, 2018 =
Tested piping macros started to create a short video with installation instructions.

= Wed Jan 24, 2018 =
Rewrote [[PVC Pipe and Fittings Library#Macros]] section of the piping macros.
=== TODO: ===
Rewrite and restructure [[PVC Pipe and Fittings Library]] to gradually provide information from necessary to advanced and to the background technical information.

= Tue Jan 23, 2018 =
Preparation to developer meeting and tested and fixed bugs in [[File:create-coupling.fcmacro]], [[File:create-tee.fcmacro]] and [[File:Create-elbow-alpha.FCMacro]] macros.

= Sun Jan 21, 2018 =
Updated [[File:create-coupling.fcmacro]], [[File:create-tee.fcmacro]] and [[File:Create-elbow-alpha.FCMacro]] macros. Updated [[PVC Pipe and Fittings Library]].

= Sat Jan 20, 2018 =
Added [[File:create-coupling.fcmacro]] macro. Added [[PVC Pipe and Fittings Library#Couplings]] and [[PVC Pipe and Fittings Library#Coupling]].

= Tue Jan 9, 2018 =
Made preparations for developer meeting and attended it.

= Sun Dec 31, 2017 =
Added [[File:create-elbow-alpha.FCMacro]] for an elbow with an arbitrary angle between 0° and 180° to [[PVC Pipe and Fittings Library#Elbows]].

= Sat Dec 30, 2017 =
Updated [[File:create-elbow-90.FCMacro]] macro. Now dimensions are stored in a separate CSV file. This macro was previously named [[File:create-elbow.fcmacro]]. Updated [[PVC Pipe and Fittings Library#Macros]].

= Thu Dec 28, 2017 =
Updated [[File:create-pipe.fcmacro]], [[File:create-elbow.fcmacro]] and [[File:create-tee.fcmacro]] macros.

Tried to create 2D documentation pictures for fittings dimensions, but:
=== Problems ===
* I have problems with the cut-function in FreeCAD.
* I tried to create 2D drawing in FreeCAD, it is not easy. I started to use LibreCAD, maybe it is better for 2D than FreeCAD.

= Sat Dec 23, 2017 =
Tried out FreeCAD library and Flamingo FreeCAD add on.

* FreeCAD library contains some pipe fitting objects but no macros. The FreeCAD library can be used as for ideas how to make FreeCAD or fittings.
* Flamingo is interesting, maybe I will contribute to it.
* I added a warning message with a suggestion for a solution to [[File:Create-pipe.fcmacro]] when no documents are selected.

= Fri Dec 22, 2017 =
A github user luzpaz asked me on github if it OK to add my macros to
[https://github.com/FreeCAD/FreeCAD-library]
and also mentioned [https://github.com/oddtopus/flamingo].
I am thinking about doing this.

= Wed Dec 20, 2017 =
Fixed bugs in FreeCAD macros

=== Problems ===
* During the macro development, I used a FreeCAD command line for testing. The macro works, but it crashes next day or it crashes on a different machine.
:* The reason for the crash are objects which I create with the command line. My macros can refer to them but during the next run these objects do not exist any more.
* Before I run a macro, I create a new document. My macro assumes that such a document exists. I know, why I need this document, but other users do not know this. The user runs my macro and is :(.

=== Solutions ===
* Test macros after FreeCAD restart.
* Testing by other users is important.
* On a failure, Let the macro show a hint to the user, what went wrong and what the user should do.
* Instructions are very important.

=== TODO ===
* (Video) instructions how to install macros and how to use it.
* Add instructions to the macros.

= Sun Dec 17, 2017 =
Add new version of a pipe FreeCAD macro [[PVC Pipe and Fittings Library#Pipes]]. Better code and GUI.
Add new version of a 90° elbow FreeCAD macro [[PVC Pipe and Fittings Library#Elbows]]. Better code and GUI.
An angle between 0° and 180° is possible but I have GUI and parameters only for 90°.

=== TODO ===
* improve integration of various macros into FreeCAD
* separate data from the logic to prevent Licensing Problems. The Macros will be published under CC0 public domain.

= Sat Dec 16, 2017 =
Created git hub repository [https://github.com/rkrenzler/ose-piping-library] for the macros. Added a macro for tee-parts [[PVC_Pipe_and_Fittings_Library#Tees]].

= Fri Dec 15, 2017 =
Looked for literature about technical standard in a library.
Some interesting German documents are:
* DIN EN ISO 1452-3 Kunststoff-Rohrleitungssysteme für die Wasserversorgung und für erdverlegte und nicht erdverlegte Entwässerungs- und Abwasserdruckleitungen - Weichmacherfreies Polyvinylchlorid (PVC-U) - Teil 3: Formstücke (ISO 1452-3:2009).
* DIN EN ISO 1877-3 Kunststoff-Rohrleitungssysteme für die Warm- und Kaltwasserinstallation - Chloriertes Polyvinylchlorid (PVC-C) - Teil 3: Formstücke (ISO 15877-3:2009 + AMD 1:2010); The same as DIN ISO 1452-3 but for PVC-C.

Some documents with possibly useful information:
* DIN EN ISO 3126 Kunststoff-Rohrleitungssysteme - Rohrleitungsteile aus Kunststoffen - Bestimmung der Maße (ISO 3126:2005); It describes how to measure pipes.

Book:

The standards contains too much information spread in many documents. They are also expensive to obtain. Maybe books are better.
* Piping databook, Nayyar, Mohinder L., McGraw-Hill 2002. It containments measurements for some pipes and fittings in one place. It is not clear, if this information is sufficient for CAD-files.

=== Problems ===
I tried to make a simple tee-fitting in FreeCAD. It is simple only theory -- the FreeCAD refuses to perform boolean operation on shapes for unknown reasons. I wasted a lot of time moving parts back and forth, until FreeCAD does what it suppose to do. I felt like a pigeon in the Skinner experiment. [http://psychclassics.yorku.ca/Skinner/Pigeon/]

= Sat Dec 10, 2017 =
Uploaded improved elbow FreeCAD marco [[File:create-elbow.fcmacro]] with GUI. It can create some 40 Schedule 90°-elbows.
=== TODO ===
* Add more parts. Add progress information -- the macro needs some time to create an elbow, but the user does not have any feedback when clicks OK.
* All previous macros are experiments and not a finished work. Find out these Idea behind the macros is good enough. If it is, complete one macro.
* Maybe it is better to use a repository instead of loading each change to the Wiki?
* Find out what is Wrong with FreeCAD. Why cannot I do a cross section (easily)?)
= Sun Dec 9, 2017 =
Improved version of elbow-macro.
=== Problems ===
I tried to create a cross section of the pipe elbow for documentation. For some reasons I cannot cat the elbow by a large box. With small box it works. Very annoying :(.

= Thu Dec 7, 2017 =
Worked on new elbow macro. Now I used sweep for whole elbow. The work around from Dec 6 is no more necessary.

= Tue Dec 5, 2017 =
[[PVC_Pipe_and_Fittings_Library]]:
Improved FreeCAD marco [[File:Add-elbow.fcmacro]]. It creates now a single solid part.
===Problems solved ===
The Problem union of parts from Sun. Dec 3., 2017, I solved by changing the outer radius of the bent part. See [https://www.freecadweb.org/tracker/view.php?id=2831].

= Sun Dec 3, 2017 =
[[PVC_Pipe_and_Fittings_Library]]:
Created FreeCAD cad file for a PVC elbow[[File:Pvc-elbow-test-60deg.fcstd]].
Created FreeCAD marco [[File:Add-elbow.fcmacro]] to add an elbow to the active document.

===Problems ===
* I cannot make an union of three elbow parts.
===Problems solved ===
* FreeCAD ''sweep''-function cannot sweep a complex sketch -- for example with two circles. Spitting sketch into multiple sketches helped.
===TODO ===
Add gui to the macro and find standard dimensions for the elbows.

= Sat Dec 2, 2017 =
[[PVC_Pipe_and_Fittings_Library]]:
Created FreeCAD file for a PVC pipe [[File:Pvc-pipe-nps-sch40-1d8.fcstd]].
Created FreeCAD Marco [[File:Pvc-pipe-nps.fcmacro]] to add 40 or 80 schedule PVC pipes. Useful links: [[OSE_Part_Library]], [[PVC_Pipe]].

===Problems: ===
* I have no experience with FreeCAD macros and Python GUI-Library. The macro code is experimental. I do not know how to integrate my macro into FreeCAD .
===Questions: ===
* There is a note in the wiki-editor "Please note that all contributions to Open Source Ecology are considered to be released under the CreativeCommons". But I would like to release some of my code under public domain license. Is it OK?
* Where I enter hours, which I spent for the project?

= Fri Dec 1, 2017 =
I spent time looking for information about pipes. I tried to find answer to the questions:
* What are important standards?
* Is PVC really good material? Are there some environment friendlier alternatives?
* What are the appropriate technical terms in German? A verbatim translation PVC-Rohr seems not to a frequent term.

=Sat Nov 25, 2017=
I created the first working log entry.

Tried to connect D3D Australia to computer:

* Cura does not see the printer.
* slic3r crashes with "** (slic3r.pl:8312): CRITICAL **: 11:58:45.761: murrine_style_draw_box: assertion 'width >= -1' failed" as soon as I try to test the printer.

I tried to connect manually to usb device /dev/ttyACM0. It worked only with superuser permissions. I checked permissions of the device

ls -l /dev/ttyA*

crw-rw---- 1 root dialout 166, 0 Jan 1 12:32 /dev/ttyACM0

then I checked if I am in the dialout group

id -Gn ruslan

I was not. I added my self to the group

sudo usermod -a -G dialout ruslan

Reconnect. And it still does not work. But after reboot, the connection to/dev/ttyACM0 works. And cura can see the printer!

What is the orientation of the axis? [https://wiki.opensourceecology.org/wiki/D3D_Controller#Wiring] does not answer the question: Where the positive z axis points to?
I got confused by the motion of the z-axis. When I send positive z value, the printing bet moves down. This is the correct behavior, because if the bet moves down, then the printing head moves up.

Started to implement new positioning for pipe fitting in OSE-piping-workbench.

= Sat Nov 19, 2018 =

I bought some missing parts for Germáns printer: a bearing and two M6 bolts. I still need an Australia-Europe adaptor to switch on the printer.

==DONE==
* published [https://gitlab.com/rkrenzler/3d-printer-germany 3D printer CAD] files

= Sat Nov 10, 2018 =
The FreeCAD user Kunda1 helped me to setup FreeCAD debugger! [[Debugging in FreeCAD]]

Ask: by dev meeting:
* Is a BOM integration in FreeCAD interesting to us?

Like [https://github.com/openscopeproject/InteractiveHtmlBom] or [https://github.com/SchrodingersGat/KiBoM].

See [https://forum.freecadweb.org/viewtopic.php?f=8&t=31344&p=268109#p268109 FreeCAD forum].

=Sun Nov 4, 2018=
I started to learn physics to calculate mechanical properties of a 3D-printer. My motivations are

* Creating a decision support systems, which can suggest stepper dimensions.
* Technical efficiency through optimizations.
* Efficient use of human resources. Do important work which only view people can do.
* [[Mathematics of Classical Mechanics|Fun and Education]].

== BLOCKS ==
No support for mathematical formulas in the wiki :(.

=Sun October 30, 2018=
I am back. I am writing this from my mud hut, not :). There are couple of things to do:
#improve piping workbench - integration with Flamingo workbench; finish and forget.
#publish 3D printer CAD files
#repair Germán's 3D printer
#Improve the axis - automated generation of axes
#complete the OSE part library workbench
#learn cool physics for 3D printer calculations: Lagrangian mechanics.

==DONE==
* I tried to find out how to debug FreeCAD. It just does not work :(. FreeCAD crashed. How I suppose to teach someone to program under these conditions?
* I puslished ose-piping-library -- the prediscessor of ose-piping workbench -- under the CC0 license (Public Domain).

=Sun August 19, 2018=
Tried to setup Germán's D3D printer with Germáns help. Worked well. The D3d seems mostly to survive transportation well. But view parts are broken or missing.
Broken:

* One peg which holds pegs.
* A lot of magnets felt off.
* Y Stop felt off [[File:End_stop_y.jpg|100px|]].

Missing:
* One bolt which keeps a bearings in one end of the universal axis.
* One bolt which to fix heated bed
* One bearing.

I need to buy missing parts and then continue with assembly.

=Sun August 5, 2018=
* Improved CSV documentation [[OSE_Piping_Workbench#Customization|customization]] of OSE Pipe Workbench.

Rename Modules to prevent conflicts with other workbenches.

= Thu 07. June 2018 =
I met Michel from [https://collectiveopensourcehardware.github.io/about/ cos(h)] group -- a student group from Hamburg University of Applied Science (HAW Hamburg). I already met this group multiple times before -- they are nice and professional. One of their projects is [http://libre.solar/ Libre Solar]. They build [https://collectiveopensourcehardware.github.io/hardware/solarbox_intro/ Solar Box] - a device which you plug between solar panels and electrical devices. The Solar Box optimizes power conversion and stores excessive energy in batteries.

The cos(h)-team goes beyond just Open Hardware -- they make good assembly instructions [https://collectiveopensourcehardware.github.io/education/ https://collectiveopensourcehardware.github.io/education/]!

It is possible to work together on the 3D-Printer!

= Sat 03. June 2018 =
Worked on PVC-pipig work bench. Oriented elbow as in flamingo.

Add a video tutorial, how to connect two pipes with an elbow. The elbow geometry can be changed.

== Problems ==
The channel in the middle part of an elbow is not displayed correctly :(. You can see it, if you make the elbow transparent.

= Sat 02. June 2018 =

Access to https://wiki.opensourceecology.org forbidden. Why?

Today I worked on PVC-piping workbench. I changed orientation of the parts and solid elbow from x-z plane with to x-y plane with symmetry to x-y bisectrix. This corresponds to flamingo elbow orientation.

One freecad user asked me to write a ''howto to create fitting'' [https://forum.freecadweb.org/viewtopic.php?f=8&t=27641&p=237023#p236929]. I will do it.

== TODO ==
* position and rotate my flamingo elbow the same way as flamingo-flamingo elbow does. (x-y plane with x-y bisectrix symmetery instead of x-z plane).

= Sat 12. May 2018 =

Start to create new workbench. It is easy to work directly with FreeCAD Module directory.
<pre>
cd ~/.FreeCAD/Mod
</pre>

== Setup repository ==
I use Stephen's [https://github.com/skaiser/FreeCAD_Workbench_Starter FreeCAD_Workbench_Starter].

I could not fork it, because I already fork it for [https://github.com/rkrenzler/ose-piping-workbench ose-piping-workbench]. Instead I made clone of it with a new name.

<pre>
git clone https://github.com/skaiser/FreeCAD_Workbench_Starter ose-part-library-workbench
cd ose-part-library-workbench
</pre>

I create a github remote directory where I can make my code accessible for the public.

The cloned repository is still bound to Stephen's repository. I want to bound it to my github repository. I rename the Stephen's ''origin'' as "upstream".

<pre>
git remote rename origin upstream
</pre>

and add my new git-hub repository as an ''origin''.
<pre>
git remote add origin https://github.com/rkrenzler/ose-part-library-workbench.git
</pre>

Now I push my recent created repository to my github repository

<pre>
git push -u origin master
</pre>

== Adjust files ==
* edit ''README.md''. Add new project description.
* Rename OSE_ExampleWorkbench to OSE_PartLibraryWorkbench in InitGui.py, adjust text.

<pre>

class OSE_PartLibraryWorkbench (Workbench):

MenuText = "OSE Part Library Workbench"
ToolTip = "Add parts from Open Source Ecology project"
#Icon = """paste here the contents of a 16x16 xpm icon"""

</pre>

edit the last line in InitGui.py too
<pre>
Gui.addWorkbench(OSE_PartLibraryWorkbench())
</pre>

rename OSEBase.py and rename OSE_CommandButton.py to something else to prevent conflicts with other workbenches. Adjust dependent files.

= Thu 10. May 2018 =
== Looked for standard ==

[https://www.astm.org/Standards/plastic-pipe-standards.html]
* A brief list of all dimenensions and their minning is here [https://www.astm.org/Standards/D2749.htm| ASTM D2749 - 13].
* More detailed list: ASTM D3311
What we do not need:
* D 2665 – 0: Designation: D 2665 – 04, ''Standard Specification for Poly(Vinyl Chloride) (PVC) Plastic Drain, Waste, and Vent Pipe and Fittings'', This standard is more focused on material and mechanical properties of pipes and fittings.

== Thoughts ==
* Support Open Source standards.
* Use metric system.

= Mon 2. April 2018 =
Rewritten [[OSE_piping_workbench#Elbow]]. Now it uses PThk (pipe thicnness) instead of PID (pipe inner diameter). It does not create 2D drafts any more, this simplified the composed (non-solid) version of the elbow. The Flamingo version is has now the same orientation as the normal version.

AAAAAAAAhhh. I got confused by the CST-USA time. Went to the meeting 1 hour later 😭.

= Mon Mar 12. 2018 =
Programming OSE piping workbench.

== Problem and solution ==
* There are also not much examples of pivy to understand how it woks. Coin website suggests to use documentation of open inventor API. For main idea see [http://www-evasion.imag.fr/Membres/Francois.Faure/doc/inventorMentor/sgi_html/ Inventor Mentor Book]
* dir(obj) does not display all attributes. Try to guess them from C++ API in ''Open Inventor C++ Reference Manual''. If you need to get a possible list of arguments you can call something like ''obj.translation.setValue(invalid data)'' to provoke an error message with some suggestions for arguments.
* I do not know how to make hideable ports. They are always displayed.

How to test coin code:

from pivy import coin
sg = FreeCADGui.ActiveDocument.ActiveView.getSceneGraph()
sep = coin.SoSeparator() # add other objects here
cyl = coin.SoCylinder()
sep.addChild(cyl)
sg.addChild(sep)
# Remove object from the view.
sg.removeChild(sep)

== Some thoughts ==
* 3D printer with PVC frame has disadvantages: once built, the frame cannot be disassembled;
:*It can be taken apart with heat gun. Best way is to cut near the corner, heat the pipe, and then take it out. See [[Removing PVC Joints]].
* what about all PVC waste;
* Teach to build. What about basic didactic skills? What to do if something will go wrong: accident, missing part, broken part, participants with not sufficient fine motor skills.

= Sat Mar 11. 2018 =
Try to create create pipes as a pipe as [https://www.freecadweb.org/wiki/Scripted_objects Scripted Object] with special positioning and rotation commands.
== Done ==
* Pipe as a ''Part::FeaturePython''. Be careful, in Freecad [https://www.freecadweb.org/wiki/Scripted_objects examples] there are ''Part::FeaturePython'' and ''App::FeaturePython'' are used. They are not the same.

== Problems (and solutions) ==
[https://www.freecadweb.org/wiki/Pivy] points to the wrong documentation. It is [https://bitbucket.org/Coin3D/coin/wiki/Documentation here]

== To do ==
* Different view with drag and rotation points.
* Command for moving parts around.

It looks like T-Profile version for the 3D printer is not much more expensive than the PVC version.

Add all fitting to [[PVC Pipe and Fittings Library#OSE Piping Workbench]]. Tried to find out where to by in Germany PVC pipe crosses, which are not very expensive.

* Amazon: FORMUFIT F0013WE-WH-4 3-Way Elbow PVC Fitting, (Pack of 4) EUR 35,99 + EUR 11,52 shipment. WTF?
* One can also use "PVC-U T-Stück 90° 4fach", but I found them starting only with 50mm [https://www.pvc-welt.de/PVC-U-T-Stueck-90-Weiss-4fach-Klebemuffe_1]

The development of a pipe frame macro was a failure [[How piping macros are made#Failure analysis]]. [https://www.freecadweb.org/wiki/Sandbox:Flamingo|Flamingo]. Developer meeting.

= Sun Feb 11. 2018 =

[[How piping macros are made]]. Added Macro to create a complete frame box from pipe and corners [[File:create-frame-box.FCMacro]]. It is not possible now to select pipe and corner names from a list. The user must put the part names into corresponding edit fields.

One needs recent [[File:pipe.csv]] and [[File:outer-corner.csv]] to use [[File:create-frame-box.FCMacro]].

=== Problems ===
I should definitively make a pipe workbench. The customized macros for complex part like a frame box costs too much time.

= Sat Feb 10. 2018 =

Formulas to translate Formfit dimensions at [https://assets.formufit.com/tsd/TSD-F0013WE.pdf] to Macro dimensions. We use lower case letters for Formfit dimensions, then it holds:

H = a - g/2

M = g

G = H-e = a - g/2 -e

POD = d ( Note, the dimension "d" of a 1" corner does not correspond to the outside diameter of a NPS 1" pipe)

PID is unknow, just take a value from the NPS pipe dimensions.

* Added corner dimensions from Formufit. The dimension G from Aetna Plastics for the 1" -corner Part Number 413-015 seems to be wrong. 3/16 is too small. I replaced it by 13/16. On the OSE wiki, the dimensions are now from Formufit.
* Fixed pipe names in [[File:Pipe.csv]] from 'NPS xy"' to 'NPS xy in'. FreeCAD cannot edit names of the created parts if they contain '"' symbol.

=== Problems ===

* To champfer edges of the corners is easy to do manually in FreeCAD but I did not find a way to do it programmatically from a macro.

* Assembly2 stops working after I used about 4 circular constraints.

= Fri Feb 09, 2018 =
Disqus - https://disqus.com/. Developer Meeting. Started to devolop pipe corners for 3D printer frame. Next 12 weeks:
#Corners for a 3D printed frame -
#Finishing 3D corner
#Start building a PVC based printer - 12"?

Created [[File:create-outer-corner.FCMacro]], added dimensions from Aetna Plastics to [[File:outer-corner.csv]]. Added a section [PVC Pipe and Fittings Library#Corners]

=== TODO ===
I want to add corner dimensions from [https://assets.formufit.com/tsd/TSD-F0013WE.pdf Formufit], they could be more suitable for our purpose.

Add dimensions check for [[File:Create-tee.fcmacro]]. Developer Meeting.

= Sun Feb 04, 2018 =
Updated [[File:create-pipe.fcmacro]]. Now the macro is customizable and uses [[File:pipe.csv]] like the other macros. Updated [[PVC Pipe and Fittings Library#Pipes]].

Created instruction video [https://youtu.be/9FlW4C4nk68] which explains how to install pipe macros.

Updated ellbow macros [[File:create-elbow-90.FCMacro]] and [[File:create-elbow-alpha.FCMacro]]. They hide now not more auxiliary sketches.

=== Problems ===
* Why the wiki always shows a strange screenshot of the pipe: [http://opensourceecology.org/wiki/File:Pvc-pipe-cad-screenshot.png] even if I tried to updated it multiple times?

=== Problems Solved ===
From Sat Feb 03, 2018.
* The bushing uses the outer pipe dimensions for the larger dimensions of the bushing.

= Sat Feb 03, 2018 =
Created [[File:Create-bushing.FCMacro]], added bushing dimensions from Aetna Plastics to [https://github.com/rkrenzler/ose-piping-library-data https://github.com/rkrenzler/ose-piping-library-data], created [[PVC Pipe and Fittings Library#Bushings]].

=== Problems ===
* '''SOLVED''' (See the entry on Sunday, next day) There are some inconsistent dimensions for the shape of bushings which I use. See the picture below:

[[File:bushing-dimensions.png]]

If dimension "PID" is smaller than "POD1" then this bushing shape is not possible. This problem occurs for example in a 3/8"->"1/4" bushing with the part name "437-052" from Aetna Plastics.

* There are no dimensions or shape for the hexagonal or octagonal part of the fitting. There are also no dimension with the conical inner socket part. I just invented these dimensions and they should be considered to be symbolic and do not resemble the real parts.

= Fri Feb 02, 2018 =
Improved in [[File:Create-cross.FCMacro]] added cross dimensions from Aetna Plastics to [https://github.com/rkrenzler/ose-piping-library-data https://github.com/rkrenzler/ose-piping-library-data].

Looking for the bugs in [[PVC Pipe and Fittings Library]]-Macros. Found and fixed bug in [[File:Create-elbow-90.FCMacro]] and [[File:Create-elbow-alpha.FCMacro]] - which
does not create elbows in FreeCAD 0.17. All the macros worked in OSE 1.0 with FreeCAD 0.16 and FreeCAD 0.17 with default settings for Macro-directory.

= Tue Jan 30, 2018 =
Developer meeting.

= Sun Jan 28, 2018 =
Rewrote [[File:Create-elbow-90.FCMacro]]. Added [[File:Create-cross.FCMacro]] and the corresponding
[[PVC Pipe and Fittings Library#Cross]] section. Update [[File:pvc-coupling-test.fcstd]] (it was created by a buggy create-coupling macro).

= Sat Jan 27, 2018 =

Updated [[File:create-elbow-90.FCMacro]] macro. Now dimensions are stored in a separate CSV file. This macro was previously named [[File:create-elbow.fcmacro]]. Updated [[PVC Pipe and Fittings Library#Macros]].

= Thu Dec 28, 2017 =
Updated [[File:create-pipe.fcmacro]], [[File:create-elbow.fcmacro]] and [[File:create-tee.fcmacro]] macros.

Tried to create 2D documentation pictures for fittings dimensions, but:
=== Problems ===
* I have problems with the cut-function in FreeCAD.
* I tried to create 2D drawing in FreeCAD, it is not easy. I started to use LibreCAD, maybe it is better for 2D than FreeCAD.

= Sat Dec 23, 2017 =
Tried out FreeCAD library and Flamingo FreeCAD add on.

* FreeCAD library contains some pipe fitting objects but no macros. The FreeCAD library can be used as for ideas how to make FreeCAD or fittings.
* Flamingo is interesting, maybe I will contribute to it.
* I added a warning message with a suggestion for a solution to [[File:Create-pipe.fcmacro]] when no documents are selected.

= Fri Dec 22, 2017 =
A github user luzpaz asked me on github if it OK to add my macros to
[https://github.com/FreeCAD/FreeCAD-library]
and also mentioned [https://github.com/oddtopus/flamingo].
I am thinking about doing this.

= Wed Dec 20, 2017 =
Fixed bugs in FreeCAD macros

=== Problems ===
* During the macro development, I used a FreeCAD command line for testing. The macro works, but it crashes next day or it crashes on a different machine.
:* The reason for the crash are objects which I create with the command line. My macros can refer to them but during the next run these objects do not exist any more.
* Before I run a macro, I create a new document. My macro assumes that such a document exists. I know, why I need this document, but other users do not know this. The user runs my macro and is :(.

=== Solutions ===
* Test macros after FreeCAD restart.
* Testing by other users is important.
* On a failure, Let the macro show a hint to the user, what went wrong and what the user should do.
* Instructions are very important.

=== TODO ===
* (Video) instructions how to install macros and how to use it.
* Add instructions to the macros.

= Sun Dec 17, 2017 =
Add new version of a pipe FreeCAD macro [[PVC Pipe and Fittings Library#Pipes]]. Better code and GUI.
Add new version of a 90° elbow FreeCAD macro [[PVC Pipe and Fittings Library#Elbows]]. Better code and GUI.
An angle between 0° and 180° is possible but I have GUI and parameters only for 90°.

=== TODO ===
* improve integration of various macros into FreeCAD
* separate data from the logic to prevent Licensing Problems. The Macros will be published under CC0 public domain.

= Sat Dec 16, 2017 =
Created git hub repository [https://github.com/rkrenzler/ose-piping-library] for the macros. Added a macro for tee-parts [[PVC_Pipe_and_Fittings_Library#Tees]].

= Fri Dec 15, 2017 =
Looked for literature about technical standard in a library.
Some interesting German documents are:
* DIN EN ISO 1452-3 Kunststoff-Rohrleitungssysteme für die Wasserversorgung und für erdverlegte und nicht erdverlegte Entwässerungs- und Abwasserdruckleitungen - Weichmacherfreies Polyvinylchlorid (PVC-U) - Teil 3: Formstücke (ISO 1452-3:2009).
* DIN EN ISO 1877-3 Kunststoff-Rohrleitungssysteme für die Warm- und Kaltwasserinstallation - Chloriertes Polyvinylchlorid (PVC-C) - Teil 3: Formstücke (ISO 15877-3:2009 + AMD 1:2010); The same as DIN ISO 1452-3 but for PVC-C.

Some documents with possibly useful information:
* DIN EN ISO 3126 Kunststoff-Rohrleitungssysteme - Rohrleitungsteile aus Kunststoffen - Bestimmung der Maße (ISO 3126:2005); It describes how to measure pipes.

Book:

The standards contains too much information spread in many documents. They are also expensive to obtain. Maybe books are better.
* Piping databook, Nayyar, Mohinder L., McGraw-Hill 2002. It containments measurements for some pipes and fittings in one place. It is not clear, if this information is sufficient for CAD-files.

=== Problems ===
I tried to make a simple tee-fitting in FreeCAD. It is simple only theory -- the FreeCAD refuses to perform boolean operation on shapes for unknown reasons. I wasted a lot of time moving parts back and forth, until FreeCAD does what it suppose to do. I felt like a pigeon in the Skinner experiment. [http://psychclassics.yorku.ca/Skinner/Pigeon/]

= Sat Dec 10, 2017 =
Uploaded improved elbow FreeCAD marco [[File:create-elbow.fcmacro]] with GUI. It can create some 40 Schedule 90°-elbows.
=== TODO ===
* Add more parts. Add progress information -- the macro needs some time to create an elbow, but the user does not have any feedback when clicks OK.
* All previous macros are experiments and not a finished work. Find out these Idea behind the macros is good enough. If it is, complete one macro.
* Maybe it is better to use a repository instead of loading each change to the Wiki?
* Find out what is Wrong with FreeCAD. Why cannot I do a cross section (easily)?)
= Sun Dec 9, 2017 =
Improved version of elbow-macro.
=== Problems ===
I tried to create a cross section of the pipe elbow for documentation. For some reasons I cannot cat the elbow by a large box. With small box it works. Very annoying :(.

= Thu Dec 7, 2017 =
Worked on new elbow macro. Now I used sweep for whole elbow. The work around from Dec 6 is no more necessary.

= Tue Dec 5, 2017 =
[[PVC_Pipe_and_Fittings_Library]]:
Improved FreeCAD marco [[File:Add-elbow.fcmacro]]. It creates now a single solid part.
===Problems solved ===
The Problem union of parts from Sun. Dec 3., 2017, I solved by changing the outer radius of the bent part. See [https://www.freecadweb.org/tracker/view.php?id=2831].

= Sun Dec 3, 2017 =
[[PVC_Pipe_and_Fittings_Library]]:
Created FreeCAD cad file for a PVC elbow[[File:Pvc-elbow-test-60deg.fcstd]].
Created FreeCAD marco [[File:Add-elbow.fcmacro]] to add an elbow to the active document.

===Problems ===
* I cannot make an union of three elbow parts.
===Problems solved ===
* FreeCAD ''sweep''-function cannot sweep a complex sketch -- for example with two circles. Spitting sketch into multiple sketches helped.
===TODO ===
Add gui to the macro and find standard dimensions for the elbows.

= Sat Dec 2, 2017 =
[[PVC_Pipe_and_Fittings_Library]]:
Created FreeCAD file for a PVC pipe [[File:Pvc-pipe-nps-sch40-1d8.fcstd]].
Created FreeCAD Marco [[File:Pvc-pipe-nps.fcmacro]] to add 40 or 80 schedule PVC pipes. Useful links: [[OSE_Part_Library]], [[PVC_Pipe]].

===Problems: ===
* I have no experience with FreeCAD macros and Python GUI-Library. The macro code is experimental. I do not know how to integrate my macro into FreeCAD .
===Questions: ===
* There is a note in the wiki-editor "Please note that all contributions to Open Source Ecology are considered to be released under the CreativeCommons". But I would like to release some of my code under public domain license. Is it OK?
* Where I enter hours, which I spent for the project?

= Fri Dec 1, 2017 =
I spent time looking for information about pipes. I tried to find answer to the questions:
* What are important standards?
* Is PVC really good material? Are there some environment friendlier alternatives?
* What are the appropriate technical terms in German? A verbatim translation PVC-Rohr seems not to a frequent term.

=Sat Nov 25, 2017=
I created the first working log entry.
