Hi, i have to do a little bit of digging in this old topic. I have 3D printer with backlash (and i can't fix it mechanicaly). Script above works quite nice, but generater another problem. Because it's another move added to gcode, printhead stops for a second in place, where backlash is compensated. In this place small blob is appearing. Would it be possible, to add retraction before backlash comby kiriki-kun - Skeinforge
