Question #: 14550

Question: I am building my own laser and have watch your trocen videos.....but laser wont fire...double checked wiring and all seems correct to diagram....but the kit i bought was for a 40 watt and i amd using a 60 watt power supply and tube.....What size does the power switching unit need to be ....I think mine is too small for the trigger mA

Current Solution

Is there a test button on the laser tube power supply? You can test the laser output by using the test button. This will help you determine if the laser tube is bad, or if you have wiring issues. Sometimes, wiring to he TL may not work as some controllers are set to active low, so you may need to wire the controller to TH instead.

Additional Information:
Additionally, the mA on the high tension line does not have any relationship to the digital trigger signal from the controller to the power supply.
