As a newbie to CNC I’m hoping to get some helpful advice on setting up my laser. I’ve gone through all the forum posts on this and so far nothing has helped. Here’s the issue and the particulars of my situation.
I have a Mostics 2 in 1 desktop CNC router and laser machine running GRBL 1.1
My laser is a 5500mW Mostics laser that came with the kit.
My computer is a MacBook Pro running macOS Mojave
LightBurn successfully discovers the machine and all the axis movement controls work properly…including the z axis.
The fire laser button is set to green in LightBurn but does not activate the laser.
The laser is functioning because I can push on the pressure switch on the laser control board to turn on the laser…and the laser fires properly. With my version the laser control board is not attached to the laser itself.
I have tried 1000 and 12000 for $30…no change to the issue
I have ensured that the $30 setting equals the S-value in the device settings
The spindle motor is removed and the wiring is unplugged from from the control board.
I have tried the functioning with both the external controller attached and removed.
The wiring from the laser is plugged into the correct terminals (fan and laser) on the control board. I have confirmed they are not switched.
The control board is connected to the correct terminal on the control board.
The control board is turned on.
Can anyone help determine what I have done wrong here and help me to get my laser to fire?
