Hello,

I have an S1 with the RA2 and am trying to engrave a tapered pint glass using the rim of the glass on the rollers and the bottom on the support module.  This is the only way I can think of to get it level glass level for the laser.  When framing the glass will slide up the roller.  If I frame it multiple times it keeps sliding 1-2 mm per framing until the bottom falls off the support.  

I've thought of putting something against the rim of the glass, but afraid that would impede the rotation.

Any ideas how to correct it?  

Thanks,
