I’d like to ask for help.
My JTech laser lost all the power (and it is not the PWM change).
I did some cardboard cutting, but after a while, the job was not finished.
I thought that I had some dirt on the lens.
It looked like that - the light was scattered in a strange pattern.
I tried to clean the lens with isopropanol very carefully (I found such advice somewhere on the internet).
But it did not remove the problem.
The light is still scattered in that strange way.
It looks like your lens has cracked. If you have debris on the lens for a long time it will heat up the lens when processing and at some point the glass lens will fail and crack. You can get a replacement here:
Help. Cannot get the initial test fire for JTech 7W to go. Have tried MDI settings (M3 S??) tap play - nothing. Flip the switch on JTech controller to manual and laser fires. Have a file in Lightburn loaded on 1F…hit play and no laser but the program runs. Start it again, manually turn on laser and it burns the file but includes the tool path lines. Running 1F version 1.1.1. Have watched vids in Forum/FB/Instagram/YouTube and JTech ___ I’m stuck Standin’ on a corner in Winslow Arizona with nothin’ but JTech on my mind : /
