> How much play in your motor shaft is there? How much runout is there on the bit at the collet? How much at the end of the bit? How much at the front and back of the collet pocket?
Enough that I can move it about .5(?) mm side to side with my finger. When I try to make a dot on my copper clad board I get a circle that's roughly the same diameter. What's a collet pocket?
> Ideally there should be zero play in your shaft, but on cheaper stuff that isn't always the case. (Like, literally zero: bearings should have some preload from installation.)
Yeah, this is a super cheap motor. I'm using one of these.
> Other possibilities: Are you using the right size and type of collet, properly installed? Is everything clean and free of dirt, dust, debris, etc.?
Yeah, I'm sure I'm using the proper collet, but I've ordered another set just to be sure. This is the collet set I have, and and these are the bits I'm using. I know these have been successfully used by others. I chose my parts off this home brew machine, but actually designed my own setup.
