• E34M1 Toolhead - https://jon-harper.github.io/E34M1/ 

• Endorphin Mod - https://endorphin3d.com/ 

Compatibility 

Compatible with Single, Dual 5015 inlet, 'Owl Eyes' variant and UHF Beacon. https://jon-harper.github.io/E34M1/modules/rear 

Use with 300mm MGN12H for Ender 5 (& Pro) and 450mm for Ender 5 Plus for X and Y Axis.

Print Area

Usual print area for the Endorphin EVA 3 with 'Stage 3' on the Ender 5 is 220 x 190. This mod restores the usable print area to stock 220 x 220 with no offset.

V- wheels have less Y travel than with rails but should be less than 5mm offset towards front. Most Ender 5 Linear rails mods that place the rails on the outside will be compatible.

Ender 5 Plus - Use with Mercury One.1. bed risers available here -

Parts Details

• 6mm Belt Front & Grabber - Remixed for a single 6mm belt. V1 directs belts out the sides like stock. V2 has been altered to direct the belts out the back making the belt path 3.4mm closer to the X Gantry.

• Endstop Anchor Left & Right Switch - Bolt holes moved forward so the entire toolhead sits further back on the MGN12H carriage. This moves the belt path closer to the X gantry by 4mm and increases the Y Travel when using rails.

• X Axis Stop & Rail Block - For actuating X axis switch, 10mm adjustability. Rail block stops carriage coming off rail. 

• Z Rod Drop Brackets - Drops the Z rods 16mm allowing extra Y travel on Ender 5 and X on the Plus. For Ender 5 Plus use with the Mercury One.1 Bed Risers (link above).

• Y Axis Stop Block Arm & Switch Mount - Ender 5 & Pro only. Adjustable switch mount and arm that mount on X Gantry.
