I switched to cohesion board in July, it has worked fine with my machine so far. I tried to cut something on my laser today after two weeks of holiday - the machine worked two weeks ago without problem, only to find out that I can’t. First thing - is my tube or psu gone? Checked that and when I take out main connector - that hooks up the board with psu - I can fire the laser using test button on psu.
So looks like the board stopped sending the signal to the laser when to fire as movement and homing works fine.
Any recommendations or tips on how to debug what is going on, please
