Continuing the discussion from Homing failed error message alarm 9:
So I’ve now checked my limit switch and it appears to be working because it makes a click sound. Now, when I select home I hear a click but nothing happens. Here’s a photo of what Lightburn shows/says.
Not proof that it is good. It must be checked with a meter to confirm.
I had one that clicked, and the DVM showed it was good. It turned out the connector at the GRBL controller was loose.
Bad controller board input.
…The first three are most likely.
I got a call from Omtech support today and they are sending me a new laser. So hopefully I’ll be back up and running soon.
