Hi guys ive just run into an issue with my engraver it was running a job fine it was engraving lovely then suddenly stopped and there was a horrendous cracking sound coming from the back of the machine.
i pressed emergency stop and then investigated and when the laser if fired there is a massive bolt of electricity coming from the end of the tube and earthing out to the body of the machine every time the machine fires so i am now stumped

ive tried silicon sealant on the end as one of the other threads said but it is still arching

so any help you guys can give would be gratefully received

cheers
matt
