Hi,
It doesn't do too bad in soft materials actually, but 3mm tooling in alu it didn't like. I assumed this was because the RPM was too low, but maybe it is just the CNC-3040 the spindle is attached to being too floppy for delicate tooling. Yes I think I should have gone for a higher KV motor; I had anticipated driving it with 30V.
Anyway here is a good tutorial I found about how to increase the PSU voltage - http://cyberfish.wecheer.com/blog/?p=769
