80 Watt Omtech Laser - OMTech Laser Machine Available
Using the test button on the Laser PSU shows 5-6 mA, and a small arc at the end of the tube close to the first mirror. Placing tape before the mirror does not reveal any laser actually leaving the tube. It doesn’t appear any laser is leaving the tube. The tape never shows any marks. Looking for some pointers on where to start troubleshooting.
