Okay so here is what I was able to figure out tonight, still not up and running but I feel like im close.
I read over the Sainsmart directions which are linked here:
Genmitsu 3018-Pro 5.5W Laser Module User Guide - SainSmart Resource Center
After looking over these I learned included with the package I purchased was an aftermarket PWM inverter. This took the signal from the Shapeoko board and converted it from 0 to 5. I measured prior to this inverter and got results of 0 Vdc and after the board it was 5Vdc. This was the reason the laser was always in the “fire” state I assume.
So one question is does a shapeoko require an inverted PWM signal? If not I can take this portion out and wire the laser up per the instructions from the link I sent. I tried to do this tonight and had to rewire the connector to make this happen. I then turned on the Shapeoko and using lightburn homed the machine, which worked properly. I was also able to use the move features to move around. Knowing that worked I then pushed the PWM button on the laser driver to the “on” position. The led power light turned on as planned, laser did not fire as it had before, but it appeared very weak as the LED was flickering and would not fire the laser when I pushed the fire button in lightburn. It was at this point and confirmed with my voltmeter I realized the laser was only getting 5V instead of 12V.
So I guess my next question is where would I get 12V from the board to connect the laser to? I tried searching for schematics on the board but didn’t come up with much.
Do you think I am on the right track with this or does it still seem im lost?
