(1) I’ve been trying to search through the forum topics to answer my question. Many discussions come close, but I haven’t found a solution for my laser head homing to back right corner and grinding after I upgraded my Ruida 6442 to a Ruida 6445G controller.
Controller: Ruida 6445G
Limit switches? Yes, back (top) right – this is where I have set “home” to be.
Read/Open/Save/ Write config files - yes.
Display: X:10000 and Y: 10000.
Whenever I hit “Home” in Lightburn, the laser head goes to back right and grinds away. And whenever I boot up my laser cutter or press the Reset key it does the same thing. And whenever I try to position the laser head anywhere in the workspace using the set laser position tool / icon, it either does not respond or moves and starts grinding at the front of the machine.
I’ve tried various settings for the limit trigger, limiter polarity, and direction polarity under Lightburn’s Machine Settings. Now, I’m afraid that I may have changed too many different parameters that I’ve really kludged things up, but even when I disconnect the laser from the computer, I get the same problems – so I don’t think that Lightburn is the problem, but I was hoping it might be the solution.
