It doesn't resolve my problem. The motors are ejects filament up.

Hello. I didn't hear anything from you two days. What I need to do? Can I to modify something in the firmware?

This is my old board IMG_2651.JPG And this is my new board IMG_2652.JPG I was upload the firmware that you send me. Externally board is different location of the ports of endstop of axes. On the old board they installed parallel to ports of motors, on the new board they installed perpendicular to po...

I connected all wires like on old control board. I can not to connect wires, because the jack can connect only in one direction. The settings in Repeiter-Host like in instructions. I upload the firmware that you send on my e-mail.

Hello. I replace the control board and extruder motors came alive. But if I press the button "Extrude" in the Repeiter-Host the motor ejects the filament up. If I press "Retrarct" - the motor pulls the filament into extruder. And when I want to print anything the motor ejects the filament up. What I...

I wrote to you my results of voltage test above.

And what I need to do? Replace the control board?

I tested voltage like shows on picture. Voltage on all four wires is 12,86V, when motors on extruder stopped or moving. Voltage on wires of axes motors varies from 0,17V to 3,65V, when motors on axes stopped or moving.

Yes, when motors is moving, when motors is stopped. Always.

Voltage between GND and other pins is 0V. AC-DC transformer: input - 219V AC; output - 12,45V DC.
