Update 24.12.2019:
- Added various info to the description
Update 23.12.2019:
- Added a lot more pictures and the originally missing y endstop holder
- Added a simple reverse bowden coupling holder ( Makes it easier to feed Filament )
First of all, this is in beta, there might be smaller changes to it along the way.
This is my personal take on the Ender 5, the conversion sheds a ton of weight ( Including getting rid of all the default metal roller plates and the default 20x20 cross beam ) and results in a beast of a printer, easily outpacing custom direct extruder CoreXY builds.
Print settings:
0.3 PETG, print slow enough that the petg properly fuses
Parts:
- 2 Pcs 400mm MGN12H
- 1 Pc 450mm MGN12H
- 1 Pc 40x40x10 Aluminum heatsink for the X Stepper
- 1 pc BMG + Pancake stepper clone ( https://bit.ly/34TO7kw )
- Extension cabling for the hotend, i used 12x0.5 Oelflex stranded wiring. ( https://amzn.to/2EMiuyQ )
- SKR mini E3 1.2 board is advisable due to noise levels, but the standard board can ( surprisingly ) keep up aswell ( https://bit.ly/2MoHIHM )
- 3 pcs 20 teeth 5mm bore idlers for 6mm GT2 belts ( https://bit.ly/2PT5TjR )
- Various M3 and M5 bolts to assemble ( Up to 45mm M3 ! )
- Raspi ( Atleast 3b Model ) for klipper
- 1m GT2 6mm belt, to original x belt ist to short unfortunately ( 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 and has several features like bed mesh leveling and M81 prepared.
- The mounting plate for the extruder screws right into the pancakes stepper front plate, youll need to unscrew the stepper itself to mount it.
- You will need a carbide tipped 5mm drill bit to drill through the mgn rail for the y idlers if it is of any respectable quality.
- For hotend cooling use either this: https://www.thingiverse.com/thing:4058403 or if you want to use the stock parts: https://www.thingiverse.com/thing:3434018
- Mandatory bed braces: https://www.thingiverse.com/thing:3447280
- You can use this https://www.thingiverse.com/thing:4017068 To enable the preconfigured bed meshing
You can build the mod with 9mm wide belts aswell, if you attempt so please contact me so i can alter the idler holders to fit 12mm idlers in there.
Even though the build itself is rather painless i would advise only seasoned 3D printers to attemp it.
Depending on feedback ill add more info here.
