Indeed it would be!
Unless that message shows a distinct error condition giving us something more to analyze, here’s the situation you’ve described:
- The home switches correctly detect metal objects (when dismounted)
- … and the gantry / laser head (when screwed in place)
- The controller correctly sees the input signals (active and inactive)
- … on the proper inputs (
X-andY-) - … with the proper polarity (active = “red indicator”)
- The controller is set to move the laser head toward the home switches when it resets
- … and does so
- But the controller does not react to the switches while homing
@jkwilborn had a situation eerily similar to this:
- An input to the Ruida controller had the proper voltages
- And activated the diagnostic panel’s indicator showing the controller “saw” it
- But did not trigger its function
If that’s what’s happening to your machine, then IMO you have eliminated everything outside the controller that can be contributing to the problem, which means you’re in need of a new controller.
Not the happy ending any of us wanted, but …
