I have a problem with my banggood laser that everyone has been getting. I can get it to turn on, the button on the driver board reduces the laser power. So The hardware appears to be working correctly. The problem I am having is with the spinpwm port on the longmill controller adjusting the power. I get 100%power no matter whatever command I send in either lightburn or UGS. I have sent the setup commands ($30=100, $31=0, $32=1) to enable laser mode and set power range.
I can burn a project using light to control the laser position but not the power and the same with using UGS and gcode. The gcode clearly adjust the power but I am not seeing that on the laser side. I am getting 2.5V at pwm/ttl pins on the driver board and at the spinpwm on the longmill controller no matter what commands I send. I’m not sure what else to do? Any suggestions. Andy from Sienci suggested I look for answers here. Any help would be aprreciated.
