Hi Daniel and Guy,
Thank you for your input.
To clarify: My Shapeoko XXL has prox switches for homing. I also have the Z-Plus, zero probe and bit setter. My Carbon Motion is Build 513.
I entered Daniels code without any errors. But the Carbide Motion screen did still show the same XY location which I thought should have changed?.. Also, when I tried to jog, then any jog button made it move into the same direction (towards me and left), making the XY location on the screen more negative for both the X and Y axis.
Because my Carbide Motion is set for millimeters I also tried to enter G90 G21 G10 L2 P1 X-200.0 Y-200.0. That code also sent without any errors, but still no change of the XY location on the CM screen. However, this time I could jog normally afterwards.
I browsed to the links that Daniel provided and they are great. I just need time to study all that new stuff. I appreciate though if anyone could help me get started, suggestions for what I am missing and what I should try next?
