Ender 5 X and Y Axis Endstop re-orientation

Endstop relocation for X- and Y-Axis for Creality3D Ender 5

WARNING!

If you don't do this correctly, you might damage your printer!

USE AT YOUR OWN RISK!

When installing, DO NOT, I repeat DO NOT USE AUTO HOME!

first try: disable steppers, or turn off printer, and SLOWLY! move the carriage/gantry by hand. (moving quickly will generate too much current and may damage your mainboard)

when satisfactory, turn on printer, and use the menu to move the axes with 1mm steps, and carefully listen for the click (that activates the switch) so you know it functions.

then, and ONLY then, when both switches activate properly, only then use auto home.

validate the position of the X-carriage. 0 should be on the edge of the bed, or a little to the center, never on the outside.

AGAIN! USE WITH CAUTION, AT YOUR OWN RISK.

It works beautifully for me, but that does not guarantee ANYTHING.

I will NOT take responsibility.

edit (may 11th, '19): extended version in 3 variants are now available. the orientation of the holes limit the way the plate can be rotated.

1. Why?

The X-Axis endstop is triggered by a wheel, at speed it even lifts the carriage somewhat. That cannot be good for the switch. I wanted to have a static portion of the hot-end carriage hit the switch.

The Y-Axis does use a static portion of the gantry assembly, but the bump against it is really strong, possibly damaging the switch and/or original switch assembly.

2. How?

The switches can be used to bump against, but they have a slanted strip of metal, which can be grazed. With precise orientation, the metal plate of the X-Carriage and Y-Gantry can graze the switch, activating it at the exact right moment.
For this, however, the switches need to be physically flipped to put the metal strip in the correct orientation.

3. X-Axis

The X-Axis requires the most attention.
The new plate needs to be very precisely positioned to

• not have the metal plate bump against the side of the switch, but barely miss the bend of the metal
• activate the switch around 4 mm in.

• keep a valid x-zero-position after homing. Use the original screw and Hammer nut.

  The switch assembly is screwed directly on the part with the original screws, or with 2 m2 bolts and nuts.

  If using the original screws, use an M3 tap to create a thread, or widen the entrypoint with a file, and pre-fit the screw using the "tighten 1 turn, loosen 1 half turn"-method until about three quarters of the way in.

this is the X-plate mounted

Please note the part left side in the photo is rotated lightly away from you, the viewer of this photo, and the right side is all the way rotated towards you.

this way, the left side of the metal strip, where the bend is, where it is attached to the microswitch, misses the X-carriage, but the strip itself is pressed enough to make the switch work.

This is what it looks like after homing; about 4mm in, switch activated

4. Y-Axis

The Y-axis is easier. The plate fits perfectly in the corner of the frame, just place it flush against the 2020 extrusions, and bolt it down.

Use the original nut as it has rubber to prevent loosening.
You will need a new M4x20 bolt.
