We have an XYZ-tech.com 1325 Laser with an 80W Reci Tube and Power supply and a 6535 controller. Today it was cutting a job and it stopped cutting but keep moving. I checked the coolant flow...it is there...I bypassed the flow switch...still did not fire. The Power Supply fan is not running. Any suggestions on what to check next? The machine has been used pretty steadily for the last 5 months.
