The X & Z access auto home smoothly. Whenever the Y axis is supposed to move, it jitters in place.

With the power off, we can manually move the Y axis and it moves smoothly, no jittering.

This only happens on the Y axis while the steppers are powered.

Please tell me this is something fixable.

Can you move the bed in the Y axis by hand smoothly and not binding anywhere. Then I would recheck all the cables are connected securely.

If all fails then you may need to adjust the Y-Axis stepper motor current.

Check those concentric wheels I know sometimes people remove the middle ones to reduce drag

Here's that assembly video where she checks the wheels...good reference

The Y physical components are just fine. We moved the Y cable to the X axis. Any time we told the Y/X axis to move, it did it's epileptic thing.

It has to be the main board.

This is the second EFFING board we've blown in a month. And the same exact way.

Are CR-10's not for having feeble boards?

What can we do to avoid blowing another board? (Assuming we want to throw good money after bad.)

Thank you.

Never had a problem with mine, but I bought it from Hictop (through Amazon). I have since heard that they replaced the stock board from Creality, but I haven't opened my control unit to verify.

One more thing....make sure the power supply is set properly (110). My friend just bought one and had some weird issues....turns out it was set to 220
