To what value have you set that?

23

I set my Vref to 6.40 on the xyand z stepper drivers

24

According to this:

you have a current of 8A.

25

I would start by setting VREF to 0.8V (1A current). 8A will destroy pretty much any non-high-current stepper driver (and some steppers too).

26

I adjusted the Vref form 0.64 to 1.16 V which is the max voltage for the motors and they still won’t move

27

Did you mean 6.4 volts or 0.64 volts the first time?

28

I meant 0.64 volts sorry for my incorrect value

Did you compile the Marlin firmware yourself?
If not can you send a link to the firmware you used?

If you revert to Marlin do the motors move?

30

I complied the firmware myself and marlin only works if I use the stock mainboard I treid marlin with the manta and the motors also wouldn’t move

31

Please attach the Marlin config-files that work for you for comparison to your next post.

32

here are the marlin config files that I use for the stock mainboard I have sent them as txt files because the website doesn’t allow me to send them as h files

Are you sure, that this board

// Choose the name from boards.h that matches your setup
#ifndef MOTHERBOARD
  #define MOTHERBOARD BOARD_CREALITY_V4
#endif

is the same as the

If I read correctly the motors have never moved when connected to the M5P with the A4988 drivers.

It seems to me you have a hardware issue NOT a configuration issue.

Where did you source the A4988 driver boards? BTT no longer offers them for sale. Are yours actually compatible with the M5P?

Hi there no I am not sure that the drivers are compatible so I guess that must be the problem thank you all for your help I will buy some tmc’s from btt and get the board working
