# sorted's Filametrix Mod
|
|
This is a mod of the Voron Stealthburner which adds a filament cutting possibility!
|
|
|
|
|
|
|
|
## Motivation
|
|
I was looking at the ERCF MMU for several month now. What always kept me from starting the project were the discussions about issues and problems with filament tip forming. Suddenly a new company showed us how they do it quite reliable. They just cut the filament. Further motivated and inspired by the design of @pure100kim who has built the [ERCF_Filament_Cutting_MOD](https://github.com/pure100kim/ERCF_Filament_Cutting_MOD) I started to build my own version of it.

## Good to know
|
|
|
|
Please be aware:
|
|
|
|
**!! THIS IS A WORK IN PROGRESS !!**
|
|
|
|
** After my holiday trip I will mount the toolhead for another proof of concept in the printer. Once this is done I would appreciate if someone with an working ERCF unit could check it.**
|
|
|
|
- This is my very first repository on GitHub. Please be paitend with me :D - Any hints are welcome!
|
|
- We will need to use one of the ADXL mounting threads
|
|
- I designed it for main body without tool head sensor as I am planning to go with [Happy Hare](https://github.com/moggieuk/ERCF-Software-V3)
|
|
- Depending on the setup and position of the cutting point we will most probably not lose any build volume
|
|
- Currently the design is only available for the Dragon hotend
|
|
- As my ERCF is under construction I tested it with roughly 100 cuts by hand not seeing any wear or fatigue
|
|
- For the main body i remixed the ECAS version from [Alexanderor](https://www.printables.com/de/model/433797-clockwork-2-ecas-fitting-for-ercf)

### Parts list - considering you already have a Stealthburner with Dragon Hotend
|
|
|
|
#### Toolhead:
|
|
- Loctite
|
|
- 1x M3 nut (DIN934; ideally a countersunk tool to modify the nut for proper filament insertion)
|
|
- 2x M3 washer (0.5mm)
|
|

|
- 1x M3x8 SHCS
|
|
- 1x M2.5x16 SHCS (15-18mm works)
|
|
- Spring of ballpoint pen (L=15mm; D<=4,5mm) (I've ordered some for testing, to have a "defined" spring)
|
|
- Typ 4 Sharp Metall Skalpel (we will cut it to length) [Link](https://de.aliexpress.com/item/1005005117830095.html?spm=a2g0o.order_detail.order_detail_item.9.47c26368QwSbBr&gatewayAdapt=glo2deu)
