I repaired an Epilog Legend EX. It had a fire, works great now. The interlock on the Epilog is magnet based and set up so the laser stops when the lid is opened. This is a safety issue.
I always thought that the magnet completed the circuit and when the lid was closed, the circuit was closed and the machine would run.
Since my repairs, I see the two sensors near the lid, but the laser does it's works lid up or down.
Recently I had someone use the laser and had a flare-up. They lifted the lid and the laser did not stop, a flame up occurred and the lens cracked.
So now I am motivated to figure this out.
Epilog is understandably vague on what to do as this is a safety issue and liability.
Other than looking for shorts or opens in the wire, are there any ideas on how to debug and get the interlock to work. We were even thinking about putting a toggle switch to set off the sensor to stop the laser using the sensor wires present.
Am I on the right track, or does Epilog do something tricky.
Maybe the sensor melted in the closed position? Does anyone know the proper operation?
thanks,
