We have a shapeoko 3XL and Carbide Motion (build 640) randomly will change the “Machine Position” display from relative to where we have set the zeros to absolute coordinates from home. Rebooting will not change them back.
Does anyone have a trick to set them back to displaying the relative coordinates?
Note we never switch to absolute coordinates in the G-code. We’re always working relative to the offsets.
I too had to have this toggle effect pointed out. It’s very useful to know the Machine Position if you’re switching between projects which require multiple visits to the machine.
For a given project, write down the Machine Position coordinates for X and Y when homed. Do another project with a new home. When you return to the previous project, return to these coordinates and re-zero the X and Y. You can easily do this in CM’s MDI panel by entering:
/g53g0x-nnny-nnn
where “nnn” is the machine coordinate for that axis.
Some folks use the six rapid position buttons in the Jog panel but this is more versatile, you’re not restricted to those set positions.
Thank you as well for the information. So far I have only used the rapid jogs from the homing position to start projects. I’m a long ways from foraging into the Gode…
