Marlin was not recognized on USB

Setting up Lightburn on my Marlin was a nightmare:

  • the laser was recognized as a grbl M3 (that was wrong and I was just able to cut when I edited the gcode).
  • I created an other laser in lightburn as a Marlin-device manually but was not able to connect to it (even by updating the drivers in Win11 and on the SRKpro-Board).

Solution: close Lightburn, open the Laser in PonterFace (!!!), close Ponterface and reopen Lightburn - then the Marlin was accepted and connected!!!
