Hotend crashing into bed again
TwoTone last edited by TwoTone
It's been a few months since we used the printer. Not sure what is happening.
Firmware 1.21 w/ IR probe
I've gone through the IR calibration. Heated everything up, brought the hot end down until it just grabs a piece of paper- set the Z height G92 Z0, then backed off 5mm and probed with G30 S-1 at entered that in the config file.
I have measured and remeasure the home height, even used the control panel to raise the hotend until it touched the stops to confirm my measurement.
Anyway, even after all that is done, if I manually bring the hotend back down until it just grabs the paper again, the Z height reads at around 85mm.
I just don't see what I'm missing.

I'm not a delta user but maybe this could help guide you.
