When I do the upgrade, Lightburn (rinning Win11) stops communicating with my OMTech CO2 laser. I am connected via USB. If I revert back to 1.04.05, it starts working again. Anyone else having this issue?
Could you provide a bit more data please
a) have you tried a intermediate update from 1.4.05 → 1.5.02 for example
You can obtain it here
b) on latest version, in the laser tab, drop down in front of devices do you get (auto) or you have the USB serial showing
My laser connects to COM3 - the newer versions of LB (on my computer) set the COM12 by default.
Check this part of your work screen: DEVICES - click the drop down to select COM3
