Hello everyone, I hope there is someone here who can help me? I had built a heavier frame with heavier externally driven motors. I use a GRBL board for this (will add a photo of the board below). I connected a blue diode laser to this. I use the S30 Ultra 33W laser from Sculpfun. As soon as I turn on the machine the laser also turns on and I can’t turn it off. the laser beam flashes very quickly when it is on. The board has a 3-pin 24v laser connection with PWM. I have tried everything but can’t figure it out, does anyone know a solution???
Considering this is a DIY project, you did not give us much information.
There are 3 laser sockets on that board. Which one did you use?
Did you use a 48v supply to feed the board?
Have you changed any GRBL parameters? If so, which ones?
What do you mean “externally driven motors”?
Did you check the +24v to the laser to see if it is oscillating?
Do you have a DVM?
Do you have an oscilloscope of any kind?
Do you know how to use electronics test equipment?
I recommend you unplug the laser until you get everything else fully operational.
