Lulzbot TAZ 1.0
From HacDC Wiki
2019.01.17
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.

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.
