GRBL Report (?) Axes Reset Possible?

LightBurn Hardware Compatibility GRBL

I’m using Grbl 1.1f on an Eleksmaker A3 (no end stops) and would like to be able to clear the coordinate offsets returned by the report (?) command.

Send: ?
Recv: <Idle|MPos:-140.000,100.000,0.000|FS:0,0>

I’ve come up empty. Even soft reset ("\x18") doesn’t work.

I’d like to be able to use those results to maintain state for a relative home position in a plugin (for OctoPrint) I’m developing.

G92 X0 Y0 will set the current location to 0 on X and Y

I have tried G92 X0 Y0 and it does not clear G92 nor does it change the axes values reported from ?

G92.1 clears out G92 but Report (?) still shows the offset.

Try setting $10 to 0. You are reporting your absolute machine coordinates, not workspace coordinates. Then you can use G10 L2 P1 X0 Y0 to set the current workspace offset to zero.

that did it… MPos changed to WPos as well. Thanks for the pointers.
