Hmmm…checked all of the GRBL settings and the log shows that they’re set per the original shapeoko 3 settings, with the exception of $14. That one is on the FAQ document, but didn’t show up on my log.
How do I reset all of my work coordinate system settings in GRBL?
Would it be /G10 P[1-9] L20 X0 Y0 Z0 using the MDI section in carbide motion?
