Stepper mottor not working on Delta G2s

[stiop]

Hi, I have a problem with the x stepper mottor. It won't move up properly just jerks around in its place. I adjusted the tension on the belt, no help, also switched the x motor connection to the y motor and that one started to jerk and stay in its place. I double checked all the board connections, there is something definitely wrong on the board. Anybody had this problem before?

And did you try to regulate the current for the stepper motor?

I think you can increase the voltage of motor driver board A4988
