are you sure that your Motor Connections are right?

A+/A- and B+/B- checked with Ohmmeter?

test with disconnected ENBl+/ENBL-?

if you do "Manual" steps (5v) to PUL+/PUL- the Motor must do a single step.
anything is possible, just try it.
if you find some mistakes, in my bad bavarian english,they are yours.

Attached is manual of the DM860A
Check your max. current (SW! SW2 SW3) and microstep (SW5 SW6 SW7 SW8) settings too.

What are they set now?

Motor connections are right.
Manual steps not working.

That manual I already had but it can’t fix my problem.

SW1 to SW7 are off SW8 is on.
Motor is 5.6A

It may not be the issue
But current sw 1-3
 on off off is better you should not supply more current than motor to avoid burning the windings.
If motor is  1.8deg 200 pulse give 1 rev.
So usually people use 8 microsteps
Switch 5 -8 should  be  on off on on

Your setting of 51200 steps per rev may be the reason the motor cannot turn.
1600 steps per rev. Switch 5 -8  on off on on
is likely to fix your problem if you have a 1.8deg per step motor.

That seems to be the solution. Now it runs perfect!!
Thank you :)
