I’m a newbie. Lightburn finds my Ortur Lasermaster 2 Pro S2 but won’t connect. The Laser panel indicates “Ready”. The Console displays “Waiting for connection …” twice, and then about a dozen "G0"s. The Move panel is dead - won’t move the laser head. However, Lasergrbl is able to operate the laser. I can move the head and turn focus on and off. I’ve rebooted the PC and tried other USB ports, but it Lightburn still won’t connect. How can I diagnose this problem?
things to check in order
a) isyour machine setup as a GRBL device
b) are you selecting the correct COM port
c) is lasergrbl closed, you cant have dual connectiosn to the same com port
