Hi, just received my A30T this WE.

I faced the same issue while printing the 3Dbenchy boat.
After many tests, I found that reducing the speed to 80% using the printer panel (during the printing) has solved the issue.
It seems the acceleration is too fast.
I will check to reduce only the acceleration to not have to much impact on the printing time, but also to have a permanent fix.

Hop that can help.

Solved my layer shifting problem by repacing both the X- and Y axes stepper motors with S42B closed-loop stepper motors (and installed a smoother on both axes while I was at it). Never seen any shifted layer anymore.
Cheers!

Can you share a link to these motors?

As Mlauber says, please can you share a link for these steppers.
I'm having problems with my A30T Y axis.

I ordered some s42b V2 but when I installed them my machine started freaking out. Installed on the y-axis and the z-axis motors all the sudden start acting independently and grinding and all this other stuff. Did you change anything in your firmware to make these things work? Any help you can provide would be appreciated

Hello, everyone, if the motherboard of your machine cannot replace the driver, you can try the following Cura configuration file to see if the layer shift phenomenon still occurs.
