DOWNLOADED LATEST LIGHTBURN ON MY PC HP WINDOWS 11 TRIED CONNECTING TO MY LONGER GRLB LASER ENGRAVER V 1.9,11. UPDATED DRIVER CH340
LONGER LASER WORKS FINE WITH THE LONGER FREE GRBLSOFTWARE
I FOLLOWED THE SETUP INSTRUCTIONS TO CONNECT LIGHTBURN TO MY LASER
LIGHTBURN DOES NOT FIND IT. I MANUALLY SELECTED IT FROM THE MENUE
WHEN I TRY CONNECTING IT SHOWS LASER READY BUT SAYS LASER IS BUSY AND SHOWS 100%
i HAVE RUN THROUGH THE STEPS A DOZEN TIMES FOLLOWING THE SETUP INSTRUCTION VIDEO. IT WILL NOT WORK.
I BOUGHT THE PROGRAM BEFORE I TRIED THE FREE TRIAL.
ANY HELP WITH THUIS WOULD BE GREATLY APPRECIATED
I bought the program before I bought my laser. There are lots of Longer brand lasers running the latest version, so you should not worry.
So we know what we are working with:
- Laser model, and type (10w diode, 40w CO2, etc.). = 10w diode
- Computer, PC or MAC? = HP PC
- Computer OS version. = Win11
- CH340 driver installed? = Yes
- Does the OS “ding” when the USB cable is connected?
- Does the USB connection appear in the System settings, like Win Device Manager)?
- What COM port does the System report?
- Is that COM port selected in Lightburn?
- Did you try replacing the USB cable with another?
- Is the USB cable shieled and have a ferrite (big knot) supressor on it?
- Is the PC connector USB-A or USB-C?
