Hello,
Thank you for taking a look.
I have a 5x10 router running mdrive steppers on x and y. They work great, the drivers are married to the motors and are super simple to set up/wire.

I'm installing a new standard type nema23 on the z axis. It has the normal separate driver. I need help figuring if it needs to be wired with resistors and if so their values.

I'm going to run this stepper:
Manufacturer Part Number: 23HS45-4204S
Motor Type: Bipolar Stepper
Step Angle: 1.8 deg
Holding Torque: 3.0Nm(425oz.in)
Rated Current/phase: 4.2A
Voltage: 3.78V
Phase Resistance: 0.9ohms
Inductance: 3.8mH ± 20%(1KHz)

and this driver

Input Voltage: DC24V~60V
Continuous Current: 7.5A
Max Pulse Frequency: 200K
Default Communication Rate: 57.6kbps
Overcurrent Protection: Peak 10A±10%
Over voitage Protection: Peak 90VDC

with his power supply:
48V/7.3A Switching CNC Power Supply (KL-350-48)

I'm running step and direction only, no enable

I'm thinking I need a resistor on PUL+ and DIR+ ?? I have spent a few sessions/hours on the interwebs searching for specific info. Any help is much appreciated!!
Any help in figuring the values would be great if this system needs a resistor.
Thanks Again
