It was working correctly on one board but the Z motors would not operate. replacing the board brought the Z motors into play but lost the X

Have tried 3 cables and 4 stepper motors. Still the same, vibration but not turning.

Hi, I replaced the stock board in a Chiron for a Duet2 WiFi. No matter what I did, I could not get the Z motors to turn, they would only vibrate. I had a second board so I just replaced it. Now the Z motors work but the X motor vibrates and moves in both directions for a few centimetres. I used the same SD card with each board. What am i doing wrong?
Thanks

Found it guys, Thank you for all your assistance. The connector had come away from the endstop. All working great again now.

Additionally. when trying to home from the paneldue the head is moving about 10mm each time i press it AWAY from the home position.

Hi, Machine has been running fine no problems. Finished a print and found the head was at the far right of the X axis, the limit switch is on the left.
When trying to home the X, I get an error message "Error bad command"

Manual move via the Paneldue will move the X away from the endstop but not more than a single movement towards it.

I replaced the micro sd card with 3 different working backups that were all previously checked and confirmed working ,but the problem still persists.
Any help would be appreciated.
Thank you.

Thank you for all your assistance. I feel rather embarrassed to ask for more.
I have the settings for my machine.

How do i put these values in my config.g please?

Thank you

@Rattlemycage, It is seemly random. On a single layer of an object perimeter, say 4 inches by 5, it might actually come to a stop 7 or more times. I tried to upload a video but my files are larger than the 4mb permitted.

I increased the speed. without success. Still stopping. What am I missing guys?
