Trying to enable homing cycle with GRBL

LightBurn Software Questions
1

I’ve got a Sculpfun S30 Pro Max hobby laser cutter, and I can’t seem to get homing to work correctly in Lightburn with GRBL. The laser cutter has x and y limit switches. I can move each axis though the move tab just fine, but the homing button results in the infamous “error:5 Homing cycle is not enabled in your Grbl settings” log message.

I’ve looked thought a bunch of doccumentation including forums on this site and the lengthy GRBL github configuration page, without success. “Auto home laser on startup” is dissabled in the devices menu, and if i enable it I get the same error message. Let me know if you need any more information about my situation or setup.

Thanks, Sam

In the Console window (edit box below white space), enter $22=1 and that will enable homing.
