+
+## 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.

+## See how it works

+
+## Good to know
+
+Please be aware:
+
+**!! THIS IS A WORK IN PROGRESS !!**
+
+- 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)
+- Based on the setup 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)
+
+## What you need
+### Print list
+- 1x SB Dragon cutting Printhead back
+- 1x SB Dragon cutting Printhead front
+- 1x SB Main Buddy Cutting with ECAS
+- 1x Cutting arm
+- 1x Knife holder
+
+### 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)
