After the last homing, before a print starts, my extruder will quickly go through all the points where it would normally auto-level via the IR sensor; however, now the bed doesn't move into place in order for the auto-level to function. How do I bring back the auto-leveling? I've tried going though S3D and inserting a G28 and G29 script, that was tragic. . . Then I reloaded the boot sd card with the original files, I also reset controls and reset EEPROM. After re-calibrating the Z-offset I tried another test print and it's still just going through the motions. I even tried pushing a .stl through the onboard slicer thinking maybe I had something wrong is S3D - nope, still no auto-leveling. Hope all is well, and thanks in advance!
