I recently installed a 10W diode laser on my ShapeOKO4, using pwm as laser power control and an additional power supply for laser. Software is Laserweb. It works fine on cutting jobs, except that it does not turn laser off between shapes, and left traces between them. It does, however, turn off laser at end of the job. I tried to send $32=1 before each job as people suggested online, so the controller knows it is in laser mode and turn off laser for G0, but doesn’t seem to work.
Adding the $32=1 should have solved the laser on/off issue. Also make sure that you have the $30=1000 and $31=0 so the pwn has the power range. $31 set above 0 will leave the laser on even when you don’t want it. You can confirm that it was added by typing $$ in the software console. I’m not familiar with the Laserweb software but there could be settings within the software causing the issue. Also check that all of your wiring is secured, loose wires at the pwn will cause the issue as well.
You could also try using something like Lasergrbl (free software) and see if you have the issue with that. If so it might be a wiring or hardware problem.
