Thanks Eddy,
Sorry, I haven't been on here for ages.
thanks for your reply. I think I need to pretty much strip all the electrcs out and start again with my machine now.
I now keep having problems with my twin ballscrew steppers losing steps sending the gantry out of alignment.
The physical wiring connections are ok, Velocity and acceleration on the motor tuning have been reduced.
I mostly use the machine for drilling shelf peg holes for kitchen cabinets, each panel has 20 holes approx, it usually gets through 4 or 5 panels but then drops steps !
Any clues ?
Because it is used for work, I could justify up to about £2000 budget on upgrading it particularly as I want closed loop steppers and a decent breakout board with a spindle speed control.

Many thanks
