Creality Ender 5 Plus – CoreXY Capybara Conversion

CREALITY ENDER 5 PLUS - COREXY CONVERSION (8MM RODS & 10MM BELTS)

This project is a complete engineering overhaul for the Creality Ender 5 Plus, transforming its kinematics from the stock Cartesian system into a high-performance CoreXY motion system.

By utilizing heavy-duty 10mm GT2 belts, 8mm linear rods, and LM8UU bearings, this modification significantly increases print speeds and accelerations while maintaining the massive build volume of the Ender 5 Plus. The main design philosophy was to minimize structural changes to the original frame while maximizing rigidity.

--- PROJECT STATUS & SHARED FILES ---

- Work in Progress: The Bill of Materials (BOM) regarding the exact count of screws, nuts, and heat-set inserts is currently incomplete.

- Files Included:

- A folder containing only the printable plastic parts.

- A comprehensive assembly model provided in .step format, featuring the frame, pulleys, toolhead, and partial insert placements for easy reference during assembly.

--- REMIX INFORMATION & TOOLHEAD NOTES --- This project includes a remixed "BambuLabs SB Adapter" based on the following publication: https://www.printables.com/model/323196-voron-stealthburner-for-bambu-lab-x1cx1-hotend

- Modification: The positions of the mounting screw holes have been changed.

- Important Compatibility Note: The Stealthburner housing from the linked model (as well as the original Voron model) is NOT compatible with the bed probe mount (BLTouch) used in this project.

--- KEY FEATURES & SPECIFICATIONS ---

- Kinematics: CoreXY conversion with minimal frame modification.

- Frame Requirements: Requires removing stock Cartesian motion brackets and installing the provided frame-stiffening mounts. No drilling or permanent frame destruction needed.

- Motion System:

- Y-Axis: 4x 510mm linear rods (dual rods per side).

- X-Axis: 2x 440mm linear rods.

- Bearings: 8x LM8UU linear bearings in total (2 for the X-carriage, and 3 per side for the X/Y gantry mounts - arranged with two back-to-back on the lower rod and one on the upper rod).

- Drive Mechanics: High-torque 10mm wide GT2 belts.

- Toolhead: Custom Stealthburner toolhead housing a Bambu Lab X1C Hotend, Orbiter 2.0 Extruder, and a BLTouch probe.

- Electronics Relocation: Requires relocating the mainboard and power supply from the stock bottom box to the side of the frame. This mod is fully compatible with this external enclosure project: https://www.thingiverse.com/thing:4790166

--- TECHNICAL COMPONENT LIST (HARDWARE BOM) ---

Motion & Frame:

- Motors: 2x LDO Nema 17 (42STH48-2504AC) mounted in the rear corners.

- Belts: GT2 10mm open-ended belt.

- Linear Rods (8mm diameter): Y-Axis 4x 510 mm, X-Axis 2x 454 mm.

- Bearings: 8x LM8UU linear bearings.

- Pulleys & Idlers (10mm width, 5mm bore):

- Front Corners: 1x smooth idler on each side (2 total).

- Rear Corners: 3x smooth idlers on each side integrated with the belt tensioning system (6 total).

- X-Axis Gantry Mounts: 2x idlers on each side (4 total). Note: Since the belt flips in this section, you can use smooth idlers or substitute one on each side for a toothed pulley.

Toolhead, Sensors & Electronics:

- Hotend: Bambu Lab X1C

- Extruder: Orbiter 2.0

- Z-Probe: BLTouch (mounts alongside the ADXL345 accelerometer on a dedicated bracket).

- Part Cooling Fan: SUNLU 24V Blower Fan.

- Mainboard: BigTreeTech SKR Mini E3.

--- RECOMMENDED PRINT PARAMETERS --- Since this modification bears structural load and handles high accelerations, parts must be printed with high-strength, temperature-resistant materials.

- Material: ABS, ASA, or PC (Polycarbonate) but remeber to bake PC-printed parts

- Perimeters (Walls): 6-12
