I found it. Unfortunately switching it to 5V didn't change anything.
However I realised that the red LED of the drivers are blinking one time every three seconds, in the manual it says "Over-current protection activated when peak current exceeds the limit."

What size motors are you driving with them?

For X-axis and Y-axis it's Nanotec 4H5618 C0408

For Z-axis it's ISEL MS110 (473030)

I am not familiar with those exact motors. That said, I just want to make sure that none of the motors will move at all?
Do they make any kind of noise when a move is commanded? Like when a stepper is stalled? Do they get hot?
If none move at all and they all trip with the exact same problem check your drives amp setting.
It may also be possible that the motors need to be wired in bipolar series for those drives to work
with them.

If your getting over current alarm, most probably the motor wires are miss wired.
Stepper motor wiring is very strict, no mixing of coils, that is something most drives will not survive.
To check wiring, connect any two motor wires together (disconnected from the drive) and turn the motor by hand, if you feel resistance = that is one winding and those two wires MUST go to A+ and A- <<<OR>>> B+ and B-, never ever between any A and any B.

I checked the motor cables for continuity with a multimeter, I didn't mix A and B.
How will I know if a drive didn't survive? The green LED lights up continuously.Stepper motor wiring is very strict, no mixing of coils, that is something most drives will not survive.

Thank you all very much for your help!

It actually was this switch. Now everything works fine.Stepper online drivers have a 24v and a 5v logic switch at the top. It needs to be 5v for the mesa
Thank you all very much for your help!
