The "newest" addition to our collection of 3D printers is actually the oldest: The Lulzbot TAZ is actually, a Lulzbot TAZ 1.0 (according to the serial number on the back: KT-PR0010-5147).

The index.html at http://devel.lulzbot.com/TAZ/ says, among other things: *"B" - KT-PR0010 - TAZ 1.0

Using minicom, the speed was determined to be 115200. Sending G28 to home it made it grind gears.

$ pronsole

Eventually, I found http://download.lulzbot.com/TAZ/1.0/hardware/electronics/RAMBo/ which identifies the board as "based off of the Arduino MEGA" with "5 stepper drivers" and "5 MOSFET switched outputs" with documentation at http://reprap.org/wiki/rambo

As near as I can tell, the latest in firmware and other software lives at http://download.lulzbot.com/TAZ/1.0/software/current/firmware/Marlin/

Lulzbot offers instructions on re-flashing your 3D printer's firmware and see also RepRap's RAMBo firmware page.

Because we neither have the original paperwork for the TAZ, nor were the EEPROM settings previously enabled, we may be forced to determine the ESTEPS settings via, IMHO, a method fraught with inacuracy by trying to manually calibrate using the OHAI instructions.

Adding a dynamic symlink to the TAZ...

After massaging the OS with the procedures listed in Dynamic symlinks for 3D printers we see:

$ pronsole

Welcome to the printer console! Type "help" for a list of available commands.

Fixing Arduino

The Arduino IDE complains

Ignoring bad library name <@pronterhost>

The library "U8glib-new" cannot be used.

Library names must contain only basic letters and numbers.

(ASCII only and no spaces, and it cannot start with a number.)

Und zo, after tracking down the symbolic links and such...

sudo -i
$ cd /usr/share/arduino/libraries
$ rm U8glib-new
$ mv /home/demo/Taz/Marlin/ArduinoAddons/Arduino_1.x.x/libraries/U8glib-new /home/demo/Taz/Marlin/ArduinoAddons/Arduino_1.x.x/libraries/U8glibNew
$ ln -s /home/demo/Taz/Marlin/ArduinoAddons/Arduino_1.x.x/libraries/U8glibNew .
$ exit
