Good morning everyone,
I have 2 cr 6 max printers with a problem:

After a few layers (about 3) the print lowers by about 1 layer; then squash the layer and continue printing.
Performs the same operation towards the end of the print.

I therefore find objects with crushed layers.

Has this happened to anyone?

I have already tried replacing all the components:
Motherboard, connection cables, leveling sensor, extruder block, axis motors, I also restored everything to the system. Firmware updated. Unfortunately he continues to do this crushing operation.

A thousand thanks
