Hey Steve, real quick, clear the TLO for the selected tool for the Z. in the tool page you can select 1 or 0. I believe it's 0. Are you already @ the travel limit for the Z axis? I would say the Z moving manually takes both of your arms pulling on it right? The machine allows you to move it off the limit but not advance beyond it.
For X, Y. make sure the table locks are free. Snugged locks might be bogging the motors. At Retrofit I think they usually take them out. Once the servos are enabled you will not be able to manually move the axis, the motors now control them, this is a good thing!! I noticed the motor noise as well and I think it's just because their not enclosed like on a VMC. Do you have the Manuals? I like the Anilams alot! Bridgeport, Hoo Rah!
