Calibration pushing deep into buildplate

I got my new Snapmaker 2.0 today and assembled it already. As far as I can tell, everything is connected as it should. All axis move, filament loading worked well.

I feel like we need an update, spe…

A) Check to be sure that the Build Plate support framework is right side up. (it’s REALLY easy to install it upside down)
B) Check that the magnetic sensor is not loose.
C) Make sure you update to the latest firmware.
