Hi there, 

New member here from UK 🖐️ 


I have been using my laser for quite a while now with no problems.


However, I have just installed a new programmer driver for my Arduino Programmer and it has all gone runny…..

in the past, the laser has always shown up in device manager as a separate item under BJJCZ LM2. Since installed the programmer driver (which has nothing to do with the laser), the laser now shows up as a com device and EzCad cannot find it….


Can anyone offer some help as I have too much on my PC to allow me to reset everything


I am really struggling here and I cannot update the driver by any was I know….. HELP!!!!!


Thank you in advance

It looks like your programmer installation replaced your USB driver.  Reinstalling EZCad should do it.  There are also some videos in the LaserEverything channel on youtube about the drivers.
