Nema 23 57mm Stepper Motor High Torque 3Nm (

Hello everyone. I am in the middle of the plans for upgrading my X-Carve with the screw drive, z-axis slider, and motors. I have the been trying to figure out which of the motors to buy, Nema 23 CNC Stepper Motor 1.9Nm ( or Nema 23 57mm Stepper Motor 3Nm ( would be best.


Manufacturer Part Number: 23HS45-4204S
Step Angle: 1.8°
Holding Torque: 3.0Nm(
Rated Current/phase: 4.2A
Phase Resistance: 0.9ohms
Recommended Voltage: 24-48V
Inductance: 3.8mH±20%(1KHz)
Weight: 1.8kg
Lead Length: 30cm


Manufacturer Part Number: 23HS30-2804S
Step Angle: 1.8°
Step Accuracy: 5%
Holding Torque: 1.9Nm(
Rated Current/phase: 2.8A
Phase Resistance: 1.13ohms
Voltage: 3.2V
Inductance: 5.4mH±20%(1KHz)
Weight: 1.1kg
Lead length: 30cm

Would the 425oz. work with the X-controller?

I carve mostly wood, the hardest being Osage, but also want to so some light metal work as well. I have the 1000x1000 orginal model and the upgraded x-axis makerslide.

Any help would be appreciated.

The x-controller is rated to provide up to 4 amps per stepper motor; it won’t be able to fully power the 425oz steppers.

Pulled from the FAQ section of the X-controller product page:

What stepper motors can be used?
The X-Controller can supply up to 4 amps per motor. You can safely use all of that power without over heating. Like a gShield, you can run bigger motors, but the current is still limited to the max of 4 amps. We recommend using Nema 17 or 23 motors.

425 oz-in is overkill for an Xcarve in my opinion.

I recommend these:

Lower inductance plays nicer with the 24V than the higher inductance of the 269 oz-in you linked.

Just note that for a Z slider, the wires need a little extension. I spliced excess from one of the other ones in and don’t have any issues.


Thanks. I overlooked the difference in the amps. Guess I just saw the 4 and moved on.

I’ll take a look at them. Thanks.
