Taz 6 not lifting back up after wiping

General LulzBot TAZ

Howdy,

I have a Taz 6 that’s been giving me a “failed to probe” error on occasion lately. At this point it’s happening almost every time. The nozzle will go to wipe itself off, stay at the height of wiping, run straight to the back corner washer, and roll over the edge of the scotch pad and bump over the probe button. Any ideas why this is happening?

Thanks,
Max

I am having this same problem. When I upgraded from 3.6.20 to 3.6.360win10, the start code changed. Instead of a list of G1 commands, there is a G12 command. The head fails to lift running into the switch at the home point. Will finish bed leveling and printing just fine. Did you find a solution? Thanks. Mike

I took the G12 out and put the series of G1 commands back in. The variables in the firmware don’t allow for any side to side motion so the zigzag pattern (G12 P1) doesn’t.

I also have the wider wiping pad from the dual extruder (3 pads wide instead of 1) so I increased the side to side coordinates to use that full pad when I’m not using the dual extruder.

I upgraded Curia and firmware and the lifting problem went away. Works fine now but only does the “new” linear wiping. Replacing the G12 command was going to be my next option. Thanks.

Do you have the G1 commands I can replace the G12 with? I upgraded and my printer keeps striking the end of the wiper :-/
