Hey guys need some advice on an issue I am having. Primary issue is that if I try and raise the extruder with the Full Graphic Controller LCD, it doesn't stop where it is supposed to. It will auto home if I select that. Then if I turn the knob to 160, it tries to go off the rails and I have to shut off the power. If I go to 150 - it goes almost al the way to the top but stops. So it's almost as if it's lost. A couple of specifics: - Robo R1+ with full graphic controller - I have tried M502 and M500 already - G28 (home) and then G1 Z(value) works fine. So if I enter 160 for the value and send the command via S3D - it stops at 160 as it is supposed to. - The auto home on the LCD works fine. Thanks!
