Hi All,

I have been having issues with very sporadic and unpredictable fill engraving. From reading through a few other posts here, I started wondering if my laser tube was shot. I have bright purple on both ends of the tube and the middle is a dull or light pale purple (crude pic attached).

AT TIMES I am also getting a “split” laser beam dot at the top of the nozzle when doing alignment. Not all the time but sporadically.

Is this a sign of a bad laser tube? Thanks all for your help!
