EnderXY - Triple Z (Ender 3v2)

****This design does not currently include the optional support arm holes - Will update when I have that change made****

I LOVE the design the original creator made, however, I have a 3v2 EnderXY, which means I did not have to relocate my PSU. I also have a 12032 aux fan mounted to the rear of my printer. The original design would require me to relocate the PSU and the aux fan, which I did not want to do.

This design simply mounts the motor above the PSU via a 250mm 2020 extrusion (you can find them for cheap on Amazon), and shortens the offset of the lead screw from the bed. You will need a 300mm lead screw.

Per the original design:

This upgrade will require a mainboard that has 3 independent stepper drivers available for Z.

PARTS for this version:

• 250mm 2020 extrusion (1x)
• M3x6 Screws (4x) - To Secure Motor to Motor Mount
• M5x10 Screws (4x) - To Secure 2020 Mounts to 2020 Extrusion
• M5x12 Screws (2x) - To Secure Motor Mount to 2020 Extrusion
• M5x16 Screws (4x) - To Secure 2020 Mounts to 4040 Extrusions
• M5 2020 T-Nuts (10x) - For Securing 2020 Mounts and Motor Mount to 2020 and 4040 Extrusions
• 300mm Lead Screw (1x)
• Lead Screw T-Nut (1x)
• 42-34 Motor (1x)
• 8mm to 6mm Coupler (1x) - I prefer flexi-couplers

----------

Assembly:

1. Using (2x) M5x12 Screws and (2x) M5 T-Nuts, start by mounting the Motor Mount to the 250mm 2020 extrusion, making sure to center the mount on the extrusion. The Motor Mount should measure 83mm from the edge of the 250mm 2020 extrusion (this number could vary per your machine/print quality - just make sure this mount is centered!). The Motor Mount includes lines on the back of the mount to make sure the mount is not tilted on the extrusion. There is also a small hole on the back to help push the motor out of the mount if needed.
2. Using (4x) M3x6 Screws, mount the motor to the Motor Mount, with the cable pointing outward, to you.
3. Using (4x) M5x10 Screws and (4x) M5 2020 T-Nuts, attached the Left and Right 2020 Mounts to the 250mm 2020 Extrusion.
4. Using (4x)M5x16 Screws and (4x) M5 2020 T-Nuts, attach the 250mm 2020 Extrusion assembly to the 4040 Extrusions on the printer. The 2020 Mounts should be FLUSH with the rear extrusions (if you have plastic caps, do NOT make them flush with those, but the extrusions themselves - see pictures). Secure the assembly to the printer

The rest of the steps pretty much match the regular build. You don't necessarily need to follow the steps listed above, I just found this order of operations useful for making sure things are centered.

For the Bed Brace:

• I found that all of my Lead Screw T-Nuts I have on hand have varying mounting hole spacings. I have provided a T-Nut Test Fit file so you don't have to print the entire brace to find out it does not fit. If yours does not fit, CONTACT ME, as I can provide a version with your desired spacing. Please measure from the edge of each mounting hole.

Print Settings and Material:

• I recommend, at minimum, printing in PETG. I've printed this in PETG-CF. Consider ASA or ABS for higher rigidity/heat resistance.
• I HIGHLY recommend printing to Voron spec:
  • Layer Height: 0.2mm
  • Infill Percentage: 40%
  • Infill Type: Grid, Gyroid, Honeycomb, Triangle, or Cubic
  • Wall Count: 4
  • Solid Top/Bottom Layers: 5

If you have any issues with tolerances, please let me know so I can make revisions!
