Is there a spot on devel for the firmware? I’m guessing one of the TAZ 7 Aerostruder files on http://devel.lulzbot.com/software/Marlin/ would work? Seems like the hardware files haven’t been updated in a minute so I’m looking at printing the Z + X parts to start modifying my 24v Taz 1 (taking the smooth rods from the X to put on the Z then grabbing the other parts then commenting out autoleveling, wipe, LCD, adding in endstops, etc)
The pre-compiled hex files can be found at the devel location that you linked. You can find all our source code for Marlin here: https://code.alephobjects.com/project/profile/6/
At the moment, the Quiver firmware is still in flux and could be a little while until we have a final version for Quiver. YMMV!
