I am doing a retrofit on a bridgeport and am having some issues.

This is what I have: original servos with US digital 500 encoders, gecko 320X, CNC4PC C10.

The table and spindle moves in the wrong direction X- when trying to move X+. I tried swapping the armetur pos and neg but the motors start to self drive with no signal to tell them to move. Is there a parameter or setting that can be changed to switch this?

With the 500 cpr endcoders and the pullies and lead screw that is stock I have to set the steps per unit at 20000 to achieve 1 inch of movement. ANd I have verified that I am not using the pulse multiplier on the geckos. When I input that information into the motor settup my speed is limited to 75 IPM. How can I change this to achieve more speed through Mach?

Thanks
