Summary

This Y Axis Limit Switch Mounting Bracket for the Creality CR-10 S5 is different then the OEM bracket supplied with the printer to overcome two major shortcomings. The OEM bracket cannot be adjusted far enough back to center the table on the Y Axis, and it will not allow full 500mm table travel.

WARNING: One very important thing to note: The distance from the top of the aluminum extrusion the bracket is mounted on to the underside of the table carriage is very small, under 0.150" on my printer, yours may vary. The thickness of the top of the new bracket thet sits on top of the rail is 0.125". Yes not much clearance. If you are going to install this bracket on your printer make absolutely sure the carriage does not hit and/or get stopped by the bracket before powering up your printer.
