It does seem that powder coating could be the issue since some of them came out pretty decent and others didn't.
I'm thinking I have the hot-dog roller type of rotary attachment. See photo.

That looks like a nice four wheel design. Definitely not what most of us think of as a hot dog roller type. Hot dog roller usually refers to the cheaper rotary units that usually have three long knurled metal rotating tubes. So named because they kind of look like the hot dog roller often found near the cashier stand at the local 7-11 convenience store where hot dogs rotate/roast for hours and hours and hours under a heat lamp.

Thank you for the explanation. At least now I know what I have. Are the powder coated polar camel tumblers any easier to engrave then Yeti's?

Gary is right. You need the cone version to do accurate repeat engravings. I am doing so many of the Yeti/yeti type cups now I can pay for the rotary cone device every week. I can't think of a single tool that has paid for itself so fast or so often.
Color on these cups is the wave of the future--that often means multiple passes.

The cone is an option with Trotec. I wish I had a chuck but for the cups and most other cylindrical work, the cone tool is dead accurate.

Tim, this is the cone version. The cones are supposed to make swapping pieces as well as centering them faster and a bit less fiddly while also providing good grip.

Wieke makes the following set of optional cones to install on their chuck rotaries. You could make your own to fit your current chuck rotary.

The good four wheel design with its rubber covered wheels are a bit more accurate due to less slip compared to the hot dog roller with its bare metal wheels. The four wheel rotary usually has a built in height adjustment function that is nice too. Liesl, for items with decent sized openings, especially lightweight items, have you tried inserting weight of some type (e.g. small sandbags)? That can help reduce slippage/inaccuracy.

No, I haven't tried some sort of weight although the thought did cross my mind once. I will have to try and experiment some time with small sandbags or some other sort of weight.
