Mike, can you give us some more details on what Drivers your using, what power supply, are you using mach 2 or 3? Can you post up some pics of your machine ?

The others will be alog shortly im sure to help you out, the above things are questions i think they will want to know.

When you say "but clicks in places" whats giving the clicking sound ? Confirm your drivers for me and we can take it from there, i know that the MCP drivers need a good supply of power when one driver is giving a fault light (red led) and adding an addtinal power supply fix's the problem 98% of the time.

Hopfully some of the more qualified chaps will be along soon.
