T6 1.1.9.x + BLTouch...

OK figured it all out - here it is if you want to give it a try - you will need to edit Config_LulzBot.h for you toolhead, change the temp sensor in Conditionals_LulBot.h and the temp sensor pin in pins_RAMBO.h unless you’re using a k-type thermocouple on pin 3 for the hotend, and change the z-probe offset values.

Bilinear auto-leveling is the method in this version - there’s no point in probing more than 4 times for linear. The FW is set up to probe a 3x3 grid.

Use at your own risk - install instructions can be followed loosely here: https://forum.lulzbot.com/t/taz-5-bltouch-project/5227/1

Thanks for posting this. I’d like to try it but it appears to be incomplete - there’s no Config_LulzBot.h for example. What am I missing here?


Same here, an issue is posted on GitHub.

Never got Auto bed leveling working reliably, so bought a BLtouch for our TAZ 6 with flexydually V2.
