first off, thanks for the wiring Tweakie!! I have been high and low trying to find a pinout for this power supply, contacted the seller and the manufacturer. apparently they only make them and its up to others to figure out how to use it...
anyway, did you ever figure out how to fix the firing problem? Mine is doing the EXACT same thing, the laser fires on Z down, and sputters on Z up leaving little trails on the rapids and it's driving me crazy. My wiring is exactly as in the diagram except on my board its pin 6 for Z direction. Any suggestions would help a lot. Thanks in advance...
