Hi everyone,
Ive recently bought a taig mill that ive converted to cnc. Ive finally got round to cutting some parts on the machine, however ive run in to a problem thats concerning me. Im peck drilling some holes in 6mm aluminium, it works fine for the first couple of holes, but after a while the z-axis zero point seems to get progressivly higher. Also after running the sam g-code a few times this holes first made seemed to become slightly elongated along the y-axis, is this perhaps a related problem?. Im using a xylotex board, mach 2 and the 1/4inch 180ncm shaft steppers from arc euro trade.

If you've got any ideas on whats causing this, your suggestions would be much appreciated.
Thanks alot,
Roland
