Hey there,

Just replaced x axis ampon my VMC15xt (the old one was amc, the new one is glentek), everything works, I get some kind of sound from the axis motor (to me it sounds like a water running through some pipe). The noise is present as soon as I power up the machine, no matter if I move the axis or not.

Haven't try any machining yet.

My guess is it has something to do with those little pots, and tunning the amp. Any advices? Anybody has some kind of procedure? Thanks a lot, guys, you helped me a lot up to this point.
