No laser fire. Possible wiring issue


(Michael Schupp) #1

Lihuiyu studio B1 board (Blue and white machine).

Cohesion laserboard

Firmware was on the sd and I have lightburn as software.

I didn’t have the option when in device setup (in lightburn) to choose cohesion3d from the options so I picked the Smoothie option. I have movement in both x and y but no laser fire unless I hit the fire button on my old lcd display and no led light from firing either. I’m guessing I have an issue in my wiring? (couldn’t find a pinout board) first pic is the old board connector and the second and third pic is the new one. So the power supply connector is lo 5v gnd and 24v. Any help would be really appreciated. Cheers


No pictures made it through. Please try to upload them again. We will need to see the machine, board, and wiring.

How are you trying to fire the laser from the software/ board?

Send some lines as explained here: PWM tuning for Smoothie Firmware such as the G1 X10 S0.8 F600

The head should move while firing. The “Laser Fire LED” in the lower left corner of the board should turn on during this time.
