Hey @NilartPax , no my SM2 works perfect, you checked the bed screws from below?

It’s important that assembled carefully, and step by step.  
Then, update the [firmware V1.7.1.1](https://forum.snapmaker.com/t/snapmaker-2-0-firmware-updates-and-downloads/5443/5) and take the newest [Luban 3.4.2](https://forum.snapmaker.com/t/snapmaker-luban-downloads-and-updates/4949/11) software.

And let us know.  
Sorry when my english isn’t perfect.

check all taht things, if the error still occurs, send a message to snapmaker support.

regards Bilzer
