thanks for the reply, yes i think im going to invest in the power supply from the link :) i think ive either got wiring issues or mach3 setup issues, there is i long starting delay (upto 5 seconds) when jogging (counters are going up but no motor movement initially) and motors run on a couple of seconds after, they dont seem to be smooth in motion, i will try and post pics tommoz as i have only done a test wiring, cables are not neat or in a box
