Update 24.12.2019: Various information added to description. Update 23.12.2019: A large number of pictures added, as well as the originally missing y endstop holder and a simple reverse bowden coupling holder (Making filament feeding easier). This is my take on the Ender 5, a beta conversion that sheds a ton of weight by eliminating all default metal roller plates and the 20x20 cross beam. This beast of a printer easily outpaces custom direct extruder CoreXY builds. Print settings: 0.3 PETG prints slow enough for proper fusion. Parts: 2 pieces 400mm MGN12H 1 piece 450mm MGN12H 1 piece 40x40x10 aluminum heatsink for X stepper 1 PC BMG + pancake stepper clone (https://bit.ly/34TO7kw) Extension cabling for the hotend, using 12x0.5 Oelflex stranded wiring. (https://amzn.to/2EMiuyQ) SKR mini E3 1.2 board recommended due to noise levels; however, the standard board can also work surprisingly well. (https://bit.ly/2MoHIHM) 3 pieces 20 teeth 5mm bore idlers for 6mm GT2 belts. (https://bit.ly/2PT5TjR) Various M3 and M5 bolts for assembly (up to 45mm M3). A Raspi (at least 3b model) is necessary for klipper. 1m GT2 6mm belt, originally an X belt, which was unfortunately too short. (https://bit.ly/396AoKy) Screws and hardware: M3 T slot nuts (linear rail to Ender frame) M5 T slot nuts (Y idler to linear rail to Ender frame) 4x M3 nuts 4x M5 nuts M3 washers M5 washers 2x M3x15 hex head (y endstop mount) 4x M3x10 panhead (extruder Nema mount) 4x M3x35 hex head (extruder Nema mount) 4x M3x45 hex head (Y belt / X rail mount) 4x M3x8 hex head (X motor mount) 4x M3x25 hex head (X to Y mounts) 4x M3x12 panhead (X to Y mounts) 1x M5x35 hex head (X idler holder) 2x M5x40 hex head (Y idler holder) 3x M5x16 hex head (idler spanners idler gear holder) 6x M4x25 hex head (idler spanners / tilt adjust) Hints: The provided klipper config.txt is for an SKR mini E3 1.2 and dials in the stepper to usable heat/power/steps/mm outputs for this machine, featuring bed mesh leveling and M81 prepared. The mounting plate for extruder screws directly into the pancakes stepper front plate; you'll need to unscrew the stepper itself to mount it. You will require a carbide tipped 5mm drill bit to drill through the MGN rail for Y idlers if it is of respectable quality.

Mandatory bed braces can be found here: https://www.thingiverse.com/thing:3447280 You can use this: https://www.thingiverse.com/thing:4017068 to enable the preconfigured bed meshing. It's also possible to build the mod with 9mm wide belts, but if you attempt so, please contact me to alter the idler holders for 12mm idlers. Even though the build itself is rather painless, I advise only seasoned 3D printers to attempt it.
