Re: 6040 CNC Router Stepper Motor Help!

The x axis moves freely when the motor is off of the machine but with the motor on the machine it has rough spots. What got me looking at this is I was running a program and the toolpath was all over the place. I don't think it is the controller. Does anyone know where to get a new stepper motor?
Stepper Motor: 57HD5401-14SB 1.8degrees 3. OA N1405
Does anyone know what NEMA number this is and how to interpret what the motor is?
Thanks in advance.

Not sure on roughness, but doesn't sound good.
Nema is just the physical size of the mounting, so replace with the same size.
There are various parameters for power, but main ones are the holding torque and amps etc. Lots of information on the net, though it can be confusing at times.
