Oh dear, it was going so well! This machine I have built has tested me at every chance. Having got motors running etc I am now at the stage when I can fire the laser for the very first time. But nothing happens.
I have disabled door and water interlocks just in case but if I press the pulse button or the test button on the PSU itself, nothing - absolutely nothing. I have an EFR F2 80W tube and an ES-80 psu. I have thoughly checked the connections to the controller (RDC644G) and all seems correct. Unless of course I have interpreted that wrong. The power supply itself powers up as the fan starts running. The Vendor settings ask to define low or high signal and I'm not sure what it should be. So in desperation I have tried both settings. To no avail.
I'm getting desperate now. Any ideas?
