Stepper Issue

Hi there,
the steppers of the X / Y axes of my MPCNC jerky in paired (serial) operation. It works in single operation, i.e. one stepper per axis. Setup is Arduino UNO R3, CNC Shield, 3 x A4988 stepper. I programmed the control via EstlCam. What’s going wrong

You should include a screenshot of your settings so someone might be able to help, include the the stepper screen and rapids screen.

It could be a mistake in the series wiring. Are you using the V1 wire kit or did you make your own?
