I have a (very deep modified) Creality Ender 4 3D printer. One of the biggest problem of this printer, and of the H-bot printers in general, is the twisting of the X axis when forces are applied by motors through the belt.

This problem involves print issue like oval circles, square shapes a little skewed, and bad printing precision.

I designed a very simple tool, to be printed in 2 pieces, that helps to align both ends of the X axis. This tool is useful also for CoreXY printers, and Ultimaker style printers.

This is the procedure about how to calibrate it :

Loose the belt tension, this step is important
Loose the X axis end screws (4 screws, 2 on each end of the axis)
Clip the tool on each end, check if the tools are fixed well to profiles
Tighten the screws very well and remove the tools
Tighten the belt and check that everything is ok

NOTE: i designed this tool based on my profiles measurements. It is a perfect design for Ender-4 profiles, bu
