Atomstack A5 pro and Metal mugs

1st let’s assume I get an enclosed space so the laser reflection doesn’t hit me. Before I go all out and buy rollers and stuff is the Atomstack A5 pro able to engrave metal tumblers or is it a waste of money to try? Also what about ceramic coated metal mugs?

I bought the rotary attachment from Atomstack and have been doing the tumblers. Fairly straight forward and simple UNTIL you try to use it with Lightburn. Now I have a hot mess. I messed with the settings trying to use Lightburn to put a name on because LaserGrbl does not have text capabilities. Now nothing it working right. Searching here for answers…
