So my issue is this- I installed repetier firmware on a RAMPS 1.4 board on my Printrbot metal with an autolevel probe. I got everything working except two things:
1. Y axis is mirrored thanks to the printrbot metal home position at the top left corner of the bed. I think I can fix that myself eventually (feel free to chime in if you know the easy fix), but it doesn't bug me as much as #2
2. I got autolevel working, but no matter what I do it starts printing exactly 3mm above the bed. The autolevel sensor triggers when the extruder is at the exact right printing height, but after autoleveling it goes up 3mm and stays there as it starts to print. I have a workaround in repetier host/slic3er where I can set the Z offset to -3mm, and it prints but the model shows as underneath the bed.
I have changed every setting I can find in the eeprom config to counteract this and nothing works. Z-probe height and max Z-probe to bed distance are both set to zero. Negative values kill the autolevel routine and positive values make the problem worse. What setting do I need to use to drop the extruder AFTER the autolevel routine?
