Great thank you just down loaded it... I got the torque wrong on reading the spec as I'm running windings in series the torque has increased from 3.5 Nm to 5Nm os its roughly 50 kg/cm.

I just do not know how much torque is required to drill PTFE with a 6mm drill.
Then how much torque is lost by running at 1K5 RPM hope fully this sheet will help.

I have the 500W supply up and working have programmed the Arduino board driving the 4.2A stepper controller, made an opto rev counter thing from half an Olham coupling.

Will post an updated picture up here http://www.mycncuk.com/forums/blog.php/2916-Bodgecurrently only one there at the moment.
