Hello. I am hoping that the wisdom of the crowd can help point me in the right direction. I have a UC300ETH-UB1 board using UCCNC and a newly acquired J-tech 7w laser. The laser has its own driver with power supply, and 2 wires that go from the driver to the UB1.
I have been successful at getting UCCNC to turn on/off the laser with "G1 F100 M3 Sxx" and M5 commands. However even at S100 the strength of the laser is very light, it does not etch into the wood. I can not seem to get 5volts to be sent to the laser driver by the UB1. When I change the Sxx to any lower value the laser intensity seems to stay the same.
I have to believe I don't have the correct wiring or UCCNC setting. Has anyone done this combination in the past? I have tried Cd+/Cd-, VCC/Cs-, AL1/AO1 with various results, but nothing I'd consider working.
Thanks in advance.
