I must echo that like Hood said it could be a number of things, usualy when i hear the tap-tap-tap, or clunk....., or tap-tap-tap i start to think it is a bad pulse signal ( from my experience ). On board graphics, poor PP...... Have heard similar sounds when the motors were not wired correctly. If it's bad pulse usualy you can't get much velocity.
When you run the driver test are you seeing a lot of spikes? Have any software which is running in the background when using Mach?
I don't know why it is varying for you, if a problem exists then would think it should be consitantly there, but, since you say it varies then could be something like a loose wire or something. Don't realy know ......
