#End Mills for HydraFabber were ordered. ETA is Aug 15th 2013. Updated [[HydraFabber CNC Mill Spindle BOM]]
#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.

# 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?
# If the coupler was drilled how precise was the enlargement?

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.

This is the fix by Martin Renold :[https://groups.google.com/d/msg/ultimaker/BNjPpoJpfrE/Xmbp0XxTWXEJ The Fix Patch]

THANKS to [https://plus.google.com/u/0/116103643227897667972/ Martin Renold]

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

I think the better way to install is:

#svn co [http://pyserial.svn.sourceforge.net/svnroot/pyserial/trunk http://pyserial.svn.sourceforge.net/svnroot/pyserial/trunk] pyserial #
#cd pyserial #
#patch -p0 < ../pyserial.patch #
#cd pyserial #
#cd pyserial #
#python setup.py install --user #
#python3 setup.py install --user #

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

== Task 1, LulzBot TAZ ==

Convert Taz FreeCAD files to Sketchup

Incorporated and continuing from [[Nate Log]].

Basic Idea: Incorporate Carriage with X_MillSpindleMount. Spindle mount is removable, so we can also mount the laser diode head.

=== Goal: ===

Find relevant TAZ parts. Convert TK0_Assembly.fcstd To Sketchup. Make groups, components and cleanup Taz sketchup file.
