When testing version 1.2.1 the print head crashes into the print bed when using Z-offset. I've got mine set at 3.32mm. First layer is set to 0.4mm, but layer hight is 0.2mm. Since my PrintInZ plate is higher than that it's good I have springs underneath ;)
It goes straight down and then up again before doing the first XY move. This can be seen in the g-code:
G1 Z0.200 F9600.000
G1 Z3.720 F9600.000
The same STL file slices as expected in 1.1.7
@atleberg, can you provide full configuration? File -> Export config
Bugfix: a move below z_offset was performed when retract_lift was ena…
…bled and lift amount was less than z_offset. Includes regression test. #2349
I found one case where this could happen, it was not covered by a unit test. I now fixed it and added a regression test.
However, I still ask you to provide your configuration so that I can check whether your case is different or this fix is enough. Thank you.
@alexrj excellent! :)
You can find the config here:
Yes, I confirm this case is fixed.
Workaround until I release 1.2.2 is to disable lift on retraction.
