Last week I had an issue with my Nice Cut 100 watt laser, the emergency stop switch failed. I ordered a new switch and installed it expecting the laser to come back to life but it didn't. I have taken my volt-ohms meter and traced power through the machine. I have power coming into the machine, I have power through the breaker on the machine, I have no power at the emergency switch I just installed. Before I had power coming to the emergency switch but not on the downstream side of the switch, the contacts in the switch had gone bad and switch was extremely hot. I don't understand why I have no power to the emergency switch now. What else do I need to look for? I thought about the power supply but I expect it to be downstream of the emergency switch so I don't think that is the problem. Any ideas?
Thanks
