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: The frame is all E3P. 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. The deck is easily printed in 4 sections. 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. 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. This configuration also worked without too much modification to the stock E3P wire lengths. 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: Deck: [a]_deck_y_chain_anchor deck_front_right deck_front_left deck_rear_right deck_rear_left Electronics: [a]_ps_clamp [a]_ps_hanger [a]_rpi3_mount [a]_rpi3_shelf [a]_rs_25_hanger [a]_skr_mini_e3_mount 2020_ziptie_clip (quantity as required to suit your wiring organization) Grill: [a]_grill_endcap_x4 grill_front_left grill_front_right grill_rear_left grill_rear_right XZ-Axis: [a]_xz_cable_cover keybak_mount_plate_a keybak_mount_plate_b x_motor_mount_a x_motor_mount_b xz_block_left_a xz_block_left_b xz_block_right_a xz_block_right_b z_bearing_block_left z_bearing_block_right_generic z_carriage_stop_x2 z_motor_mount_a z_motor_mount_b [a]_xz_tensioner_x2 ** [a]_upper_idler_support_b_right ** [a]_upper_idler_support_b_left ** upper_idler_support_a_right ** upper_idler_support_a_left ** keybak_gantry_anchor ** keybak_idler_bracket ** Y-Axis: [a]_y_axis_anchor_x2 [a]_y_axis_frame_chain_anchor [a]_y_axis_ls_mount [a]_y_front_belt_mount [a]_y_front_belt_slider [a]_y_motor_mount_a [a]_y_motor_mount_b y_axis_bed_carriage Misc: 2020_MGN12_guide_x2.stl ** 4040_rail_tool ** Denotes STL files that have not been modified from the baseline Switchwire design and are located in the Switchwire repository

This mod adds a y-tensioner to the Gizzle Ender 3 conversion. You will need a base conversion for your Ender 3 in addition to these files. You can find Gizzle's Ender 3 conversion in the VoronUsers github page. HARDWARE: m5x30 BHCS, m5x16 BHCS, m5x10 BHCS, m5x12 SHCS, m5 Nut (x2 optional), m5 Heatset (optional)
