Rotary Saga... Missing lines at beginning or end of engraving

Hey guys, did you ever figure out what was going on with your issues?

I’m having the same problems with the first letter of a word getting, for the lack of a better term, smooshed. Also have the Mansfield rotary and have already had trouble with it walking the tumbler left or right depending on the direction it spins.

It looks like the starting end is getting more power, or more than likely, not turning when it should. Everything else comes out beautifully after that though.

FYI, thanks for the idea for masking tape, I’m tired of ruining tumblers!

Thank you
Royce
