Machine: K40 m2NANo
Problem/ Question: _Laser not firing from Lightburn after a few hours of use. Installed the Coehsion 3d board without problems. Instlaled lightburn and everything worked fine. Installed mA meter(- terminal on meter to L- on powersupply, + terminal on meter to black wire running to end of laser tube) to the K10 and the laser stopped firing from Lifghtburn. K40 laser test switch fires the laser as well as the small red button on the power supply but not from Gcode or Lightburn.
I have tried taking the mA meter off and wired back to factory setup and no laser firing from LB, also addded a jumper on the Coheasion board from the G to the L, reloaded all LB software, powered on and off both computer and K40 mutiple times… Read many articals on how to correct this to no avail please help!_
