@phaedrux said in Duet Wifi - G29 causes extremely rapid Z movement and head crash:

Are you running a G30 before doing G29?

Bingo. That fixed it.
Thanks for the help. Got a new heightmap generated and printing away.

G31 X22 Y-21 Z1.582 P25

change the z offset to increase by 1mm
G31 X22 Y-21 Z2.582 P25

First thing I tried. Didn't have any effect. The problem is solved, have done several prints all perfect first layer without any slicer adjustments.

I think what happened is that the crossbar that holds the Y axis in place had slipped out of joint, throwing the XY gantry out of level. Once I snapped that bar back in, no more problem. Going to mark this one solved. Thanks for the help everyone.

Lowracer. I'm interested in converting my um2+ extended to DUET Wifi as well. Did you follow a tutorial or just figure it out yourself?

I'm scared to mess things up.

Thanks!
