Summary

The Ender3X comes with two printing surfaces, the standard and glass .

When you'd like to use the other you'll need to re-calibrate the bed height because the glass surface is 2.2mm thicker - until now!

Here's shim plate allowing the quick swap.

Adjust the bed height with the standard surface. When you like to use glass bed place the shim on the Z-microswich.

The thickness difference of the surfaces is the same as a SDCard. Sand the shim's longer (top) section even with the SDCard and you are a quite right.

Please, check that the adapter allows free movement of the microswich.
