you might want to try a ball-nose end-mill instead of drill bit. it might leave a cleaner surface. check out www.TitanMan.com. they may not be a good source for you outside the US, but a great way to learn about cutting tools.
that thing you had on the servo with the little gear thing and that pole where it went forwards and backwards, does it have a name? and can i buy one or did you make it? thanks
I am not 100% sure excactly what of the things you are interested in. Can you perhaps make a drawing of it, take a screendum and draw on that or something, so I can give you a good answer?
Do you still have this setup? I want to see one done with two magnets and then three.
First–>
You set it up just like you had it with same settings using repel of two neo magnets. Using a smaller drill probe mm or smaller.
Then–>
Do it again with two magnets on the platform and one on the probe. Make sure to move the two magnets back so the surface of the platform magnets match the original single platform magnets. Also try to keep probe magnet unmolested*1.
Post some high def pictures of the sculptures in front of rule or measured grid board along with the weight(g) and dimensions(1/10 mm) of each magnet and location.
What kind of tab(cost) would that run me?

*1 I always laugh when someone so missuses a term when trying to give directions.
Very clever setup Frits! Do you have some foto’s of the machine? I’m interested in how you built the simple XY and rotate robot. Does the magnet rotate with the object that is being carved?
