G33 correction grid z-offset
Hi Forum members!
I have a Geeetech G2S pro (delta printer) with repetier 0.92.9 and I am trying to get the auto leveling and distortion correction working.
I have followed the instructions here: https://www.repetier.com/documentation/repetier-firmware/z-probing/
I have it working to were it levels the bed (using G32 in grid mode) nicely. I determine this with the paper test at the center. I assume this means that I have a pretty good Z_PROBE_HEIGHT defined.
However, when I run the G33 command the resulting z-correction values are not close to zero. They are all around -1.5. This means that the print head slams into the print bed at z=0.
Is there some z-offset value for G33 that I should be tweaking? I thought that once I had the Z_PROBE_HEIGHT calibrated it would apply to both G32 and G33.
