Bed calibration tools - Easy to install

Easy to install spacers. Just print closest one you will get from bed autolevel system.

There is also simple tool to level Z axis against bed slinger rods (V3 KE (They are 8mm in diameter and axis are 100mm parallel to each other.

There is no need to dissasembly whole bed. Just lose screw, lift original spacer and insert under it your new spacer.

Printing settings for spacers:

Print these solid

Use first layer 0.16mm and than every layer of 0.08mm.

Or just use precise Z height.

I recomend printing all 4 at the same time .. Z offset and other settings can ruin your final calibration if you dont print them at the same time.
