Creality (20x40 Extrusion) Z-Axis Alignment Block

thingiverse

These precision alignment blocks ensure accurate calibration of your printer's Z-axis. Designed specifically for 20x40 extrusions like those found on the Creality CR-10, one block features a notch to clear the left Z-stop switch. To utilize them effectively, first raise the Z-axis about 10cm above the height of the blocks. Next, firmly attach the blocks against the upright extrusions, removing or cutting any rubber inserts if necessary for continued use. Disable your steppers and lower the Z-axis until it comes to rest on the blocks. Once in place, you can then raise your now levelled Z-axis, remove the blocks, and proceed with levelling your print bed. Follow this order carefully to ensure accurate alignment of your print bed with the Z-axis.
