I have a really cheap one that seems to apply uneven pressure across the bed. Has anyone worked with any sort of spring loaded holder that could help that sort of problem?

A common trick (also often needed when using non-gel ballpoints) is to add some extra weight to the pen (for example, put a small glass jar/cup upside down over the pen, or use some large machine nuts).

Beware that this is harder on the servo lifting the pen, so you may want to order a few extra of those (also at TaoBao/AliExpress). I've switched from the cheap SG90 servos that are often used to the only slightly more expensive MG90S with all metal gears that seem to do better.

I’m having the same issue. Which model do you have?

		Mine is an ultra cheap “hand writing” machine off taobao. There’s not really any specific model since there’s a million clones of them floating around I’ll probably have to make the holder myself but good to know others have had the same problem!
