Good Day,

I have taken my Laser Cutter out from storage and decided to start using it. Its a 90x60 60w Laser Cutter with a Leetro MCP6515 Control Board thats probably about 15 years old.

I have replaced the laser tube, and the Power Supply, The water cooler is working and flowing. Everything seems to be working normally, I can even send files to the machine and start the cut , it will move in the pattern send but the laser won't be firing.

The only time the laser did fire is when I took the 6pin connector out from the PSU and pressed the Test button directly on the PSU.

Is there anyone that Might be able to assist with this?

Looks like your Leetro MCP6515 controller is communicating with the machine but not triggering the laser.
Since the laser fires when you press the Test button on the power supply (PSU),
the issue is likely in the wiring, control signals, or a missing safety interlock
