#  Ender 3 Pro and V2 to Switchwire Mod

This is a conversion of the Ender 3 Pro and V2 to a Switchwire type coreXZ printer.  My goal was to use most of the Ender 3 components while maintaining the core Voron design look and feel.

## Overview
- This mod uses most of the key components from the Ender 3 Pro (E3P) while providing a coreXZ capability.  The highlights of this include:
1. The frame is all E3P.
2. The electronics are the stock Switchwire ones, but the E3P 24V power supply is used.  I wanted to get all the electronics under the deck as this follows the Switchwire design.  I had to get a little creative with the mounts to make this work.  I did not include the LCD display.   Mainsail (MainsailOS) is so amazing, I never use the LCD on the Voron 2.4 so I left it out.  It can easily be added.
3. The deck is easily printed in 4 sections.
4. The XZ and gantry are slightly modified from the Switchwire baseline.  The X axis rail is 300mm and is a tight squeeze on the shortened 2020 extrusion.  I wanted to keep the standard rail length in case I wanted to build a stock Switchwire.
5. The Y axis uses 2 rails.  I liked the look of it and it seemed more stable that way.  It also simplified the Y belt routing through the extrusion.  I also removed the springs on the bed corners and replaced them with spacers.  The spacers come off the E3P V-wheels.  With the bed mesh probing, this seemed like a better approach than worrying about the bed changing positions if the knobs rotated/loosened.
6. This configuration also worked without too much modification to the stock E3P wire lengths.
7. The E3P motors can be reused if you can pull off the gears.  Thingiverse has a printable gear puller (I haven't tried it).

## Images / CAD
I have included several images and the Fusion 360 CAD model.  CAD files and images are included in the repository

## BOM
A BOM has been added that is based on the baseline Switchwire.  This will not be perfect as the Ender 3's get a lot of mods by their owners.  It should help with most of the key items to make the MOD. 

## Firmware:
Use the baseline Switchwire configuration available in the Voron-Switchire repository.  The Voron-documentation has excellent instructions for making the adjustments.

## STL Files
This mod uses a combination of original Switchwire and modified parts.  Most of the parts are modified/new as the Switchwire and Ender 3 frames are much different.  I kept all the Voron naming conventions to provide consistency. The following is a listing of the STL files, organized by location:

	- [a]_skr_mini_e3_mount
	- 2020_ziptie_clip (quantity as required to suit your wiring organization)

3.	Grill:
	- [a]_grill_endcap_x4
	- grill_front_left
	- grill_front_right
	- grill_rear_left
