Everything working great till yesterday.
I was ready to engrave text image, but when turning on power, laser blowing up at maximum and no response from axes.
I tried everything I have read here till this morning (EU time) laptop restarted due to a new WIN 10 update.
After that I restarted everything: removed and reinstalled driver from Elekscam softaware, updated firmware from EleksROM 3.8, both successfully. Board is EleksMana V5.2
I can see the port on device manager, but Elekscam 3.1 cannot find COM port
T2 last registered version is able to connect tomy COM6 but not getting the GRBL greeting
So I tried to flash firmware as default getting the attached result i.e. avrdude not is sync
