I am running Lightburn connected to this board on multiple machines. All is going fine and now I want to install these limit switches.
After connecting the switches, setting $22=1 and sending $H, one of two things happens:
- No movement, machine switches to “busy” in Lighburn
- No movement, error <Alarm|WPos:2147483.648,-2147483.648,2147483.648|FS:0,-8|Pn:P|Ov:0,52,193>
GRBL settings: https://pastebin.com/UZJ0vz0T
I have tested the limit switches on another board (different brand) and they work just fine.
Any idea what might be wrong here?
