I see a few problems with your setup

The max power input voltage on the 4035 is 42 volts, running it with a 48V power supply will damage it.

The max input voltage to the step & direction inputs is 5 volts. Trying to run them with 24 volts will damage them.

What controller are you using?

I have attached the manual

I am using a STP DRV 4035. I am using the 24vdc on both driver and controller. I am using a 1/4 watt 2200 ohms resistor to drop the voltage to 5vdc at the terminals -dir and -step.

I used the 2200 resistor with the 48 volts also. The test still works on the driver. I am now using the 24vdc on both.
