Searched the forum and saw some similar issues, but was unable to parse the solutions. Feel free to poke fun at me, as you tell me how to fix this.
30 month old Shapeoko 3 XL with some miles on it. I flashed to grbl 1.1 this afternoon. When I start the homing cycle in CM4, the z-axis drives DOWN and it errors out.
I followed the procedure – I think – of sending the default XL configuration files (nothing happen on the screen after selecting “XL” from the drop down and clicking the >send< button).
I recall that this machine had a reversed Z when it was new, and that I had to modify some code through the MDI.
When I failed to find that procedure written out in simple language here, I thought I might ask for help. So “help please?”
