1/24/2024 0 Comments Woodpecker 3.2 grbl![]() I just not sure I believe the chines laser pin out. If i put a multimeter on the PWM and GND pins the voltage varies between 0 and 5V as you would expect. The woodpeck laser pinout is 12v - PWM - GND and the laser pinout is 12v - GND - PWN if I connect the laser up as you would think 12v - PWM - GND the laser is on all the time even whilst running Laser GRBL, if I swop the PWM and GND the laser holds off but the fan speed modulates as if it was varying the laser power. or use this woodpecker32schematic.pdf from 2 posts up if you have same version and search for. Wondering if Limit Switches can be connected to the stock controller card if yes, does anyone have wiring and GRBL programming instructions. I have two questions, the first I think I have answered myself. Using GRBL v1.1f The card in question is the Woodpecker CNC GRBL. I'm also using for the first time Laser GRBL, I've been using a woodpecker GRBL 0.9 to control my CNC miller and recently purchased a chines 3 pin laser, when I recieved it I released that the woodpecker 0.9 would not support the 3 pin laser so I bought the woodpecker GRBL 1.1 which does support the laser. ![]()
