I have the gantry working through lightburn but the laser is constantly on i have tryed all the different wirings i could find on line all have the laser on what seems to be 100% the moment the controller turns on. The mks dlc32 is running stock firmware i could not get fluidnc to work correctly wha…

MKS DLC32 laser always on - LightBurn Hardware Compatibility - LightBurn Software Forum

Through playing with the laser power at 0% its on and at 100% its of so i need to reverse the output if i flash it to fluidnc and import the config i can do that and get the laser to work correctly but the gantry doesn’t work with stock firmware fluidnc wont load the config for me to reverse the la…

I tried one of those boards and went back to Arduino based board.

Be careful when asking AI about the pinouts of a controller board - I’ve been burned before. There are many versions of this PCB. It’s best to look for the correct one here: MKS-DLC32/MKS-DLC32-main/hardware at main · makerbase-mks/MKS-DLC32 · GitHub You’ll find a PDF with the name PIN in the resp…

[image] WhiskeyRebellion1791: tryed all the different wirings i could find on line all have the laser on what seems to be 100% the moment the controller turns on Could you post the wiring diagram you used? If you pull L on the LPS low, it will lase at whatever the IN pwm/voltage is. This is…

@WhiskeyRebellion1791 Wait, I see, you are using the “Spindle” output of the DLC32. And I don’t see a ground wire going from the spindle connector to the PS. [image] Also, it’s entirely possible, that you need to connect the LPSU using the TTL output instead. From the Wiring Manual : [image] I…

If you have a diode laser with only two connections (wires) it’s likely you can use the spindle. Most of us have diodes with some type of pwm control. You probably don’t want to use the spindle connection with one of these. [image] Reference the board and see what it’s doing. This is after the…
