I have a Chinese 50W laser engraving machine.
Everything was perfect until today when i turned it on, the red tracer laser did not show up!
There doesn't seem to be any problems with the wires by the look of it and the whole machine works just fine except the tracer laser.
Could it be something with the wires since i simply have no idea how to play with wires and stuff?
I did not do anything to it since last night. I just turned it off after work.
PLEASE HELP!!
Thank you in advance.
