Log:

Spindle-assembly.jpg

  1. End Mills for HydraFabber were ordered. ETA is Aug 15th 2013. Updated HydraFabber CNC Mill Spindle BOM
  2. Ilan Moyer comments on milling bits used: I don't have good data on this because I usually am milling circuit boards (copper-clad plastic) with a 1/32" or 1/64" end mill at around 10in/min and a depth of 0.006". However I have cut plywood with a 3/32" cutter at around the same speed and a depth of maybe 0.05." You can see that I've only done pretty light milling. A friend of mine has used the same spindle to mill steel, but very slowly with very shallow passes.

Task 17, Questions posed to IIan Moyer about shaft and coupler mating

Log:

  1. What was the solution for mating 6061K107 (Hardened Precision Steel Shaft 1/4" OD, 10" Length) with S51CAYM050050 (1 RIGID COUPLING WITH BoreS OF 5(H7) / 5(H7)MM ON OPPOSITE SIDES )?
  2. The shaft is larger than coupler bores. Can we assume that the coupler was drilled larger to accommodate the shaft. Verse grinding the shaft down to fit the coupler?
  3. If the coupler was drilled how precise was the enlargement?


Spindledrawing.jpg*Shaft and coupler.png

Solution.

  • Corrected BOM to reflect the correction.
 SDP-SI	 A 7X 1-08021	 1	Shaft, 0.2497"ODx2.125"L	 $2.63	$2.63	
           S5147Y-G50-7	 1	Shaft Coupler, 0.125" Bore	 $10.95	$10.95	 Other bore sizes avaliable.

Task 13, Software and spindle holder Test 1 under working conditions

Log:

Fundamental pieces of software required to run the Taz.

  • Arduino software: this application allows you to install the printer firmware onto the ATMega microprocessor. This installation is required each time you want to update the firmware.
  • Firmware: there are several firmwares available for RepRap printers. The firmware is installed on the ATMega microprocessor and handles the G-code instructions received from the PC. Part of the configuration of the printer has to be done in the firmware.
  • Skein software: the most popular application to slice STL files into G-code is called Skeinforge. You need this piece of software each time you want to print a part.
  • Host software: there are also several host application available for RepRap printers. This application is responsible for communicating with the electronics of the printer before and during print jobs. It prepares the printer before starting a print job and then also starts the actual print jobs.

Task 8, Setup 3D Printing System for Linux(Ubuntu 12.04)

Log:

Installed: Ubuntu 12.04, Python 2.7, Cura/Replcatorg/Pronterface/Printrun/Slic3r

Software downloads

Printers were not able to connect to printers. This was fixed using the resources below. RepRap IRC

  1. [13:01] <stager_> how do I connect to either ultimaker or lulzbot taz with ubuntu 12.04#
  2. [13:01] <ScribbleJ> Use Pronterface.#
  3. [13:01] <stager_> I get connection timed out when I try to connect to either printer#
  4. [13:02] <teepee> check if your user is in group dialout#
  5. [13:02] <iXce> are you specifying the right baudrate ?#
  6. [13:02] <iXce> that too#
  7. [13:02] <teepee> right if baudrate is 250000, that might be a bit problematic...#
  8. [13:03] <teepee> 250000?##
  9. [13:03] <kthx> 250000 is problematic on linux, see https://github.com/ErikZalm/Marlin/issues/205 for some details about the problem and is also possible with a patch to pyserial, see https://groups.google.com/d/msg/ultimaker/BNjPpoJpfrE/gGSKAdhY5VwJ#
  10. [13:03] <stager_> yes 250000 baudrate for ultimaker and 112500 for lulzbot taz#

This is the fix by Martin Renold :The Fix Patch

THANKS to Martin Renold

Thanks for pointing this patch out, I've just upgraded my baudrate now.

I think the better way to install is:

  1. svn co http://pyserial.svn.sourceforge.net/svnroot/pyserial/trunk pyserial #
  2. cd pyserial #
  3. patch -p0 < ../pyserial.patch #
  4. cd pyserial #
  5. cd pyserial #
  6. python setup.py install --user #
  7. python3 setup.py install --user #

So the next distro upgrade won't override your local version.

Task 7 Work plan for getting CNC Circuit Mill Spindle working on TAZ:

Log:

  1. Document final BOM including spindle motor, bit holder, bearings.
    1. Embeded Google Spreadsheet for HydraFabber CNC Mill Spindle BOM to OSE Wiki
    2. Added an Edit link at the bottom of the embedded Google Spreadsheet
  2. Generate exploded part diagram in Sketchup or Solidworks referencing numbered items in BOM spreadsheet
  3. Verify and purchase parts
  4. Prepare and avail all the files for the spindle holder. Upload to wiki.
    1. STL file
    2. RAMPS gcode file
  5. Let the RepRap IRC know about this, and let Marcin know that we can add printing file and Spindle BOM to a blog post - to encourage others to develop the CNC Circuit Mill in parallel.
  6. Print Spindle Holder
  7. Secure a 5V power source
  8. Take photo and document all spindle parts and when you build it, do a Dozuki build procedure.
  9. Build out spindle, connect spindle motor to power, install an on-off switch for mill
  10. Source proper milling bits and buy them
  11. Prepare a milling bed - 1/4" plywood taped down.
  12. Level the milling bed
  13. Whenever you have free time, reach to RepRap IRC for code for milling on a RAMPS system, or search web
    1. Document all the examples you find on this - write down links
  14. Download CNC mill software and upload to OSE wiki
  15. Determine a strategy for uploading CNC Milling code to existing TAZ
    1. Use a different Arduino/RAMPS? Upload new software/firmware
    2. Document your path before making any changes.
