Make sure both the gib and the two shoes on either side of the slide are adjusted to be smooth without the motor in place. If the gib is not locked, that is both screws top and bottom snug, then the gib can slip and make it much more difficult to move the z-axis. If it's locked but too loose then the slide can cock to the left with the weight of the motor. The shoes likewise need to be held with hand pressure and locked in place so the slide doesn't hang forward.

I just purchased a Taig mill, and after putting it together I notice that the ability to rotate the Z-axis drive screw becomes difficult once the heavy motor is put in place. Pushing up on the motor permits the Z-axis screw to easily move, releasing the motor makes it difficult to turn the screw.
The system will be a CNC system in about a week. I'm concerned that the motor may not be able to move the Z-axis easily. My question is, is there a way to adjust the machine such that the Z-axis movement is less strained? Or is this how the machine is supposed to work?
Thanks,
