ERCF AutoRewinder

I used the Filamentalist MOD shared on printables.com to inject the filament from the front like a bamboo AMS, but I redesigned it as follows using the step files provided.

1. the nylon nut shape was changed to a circular shape because the filament tensioner spring could not be inserted, so a spacer was modelled as a way to tighten the nut, and then printed out to make the tensioner work properly.

2. the black part of the ECAS pneumatic fitting should be used without disassembling it, so that the PTFE tube can be securely fixed. In the future, we will change to threads so that M4 fittings can be used instead of ECAS fittings (M4 fittings have a tighter clamping force than ECAS fittings).

3. Since the beginning of ERCF production, GEAR Motor is using OMC (SteperOnline) 1.8 degree 48mm 2A, and only used 0.8A for measuring the distance from ERCF to Stealth Burner Extruider Gear, and then used 1.8A, and there is no torque shortage when loading and unloading the filament.

4. ERCF filament cutting is still using the same method that minimises unnecessary movement and is more compact than other cutting methods, as shown in the previous video.

5. Damn!!! Happy-Hare updates are a mess, especially inconsistent variable changes that make me hesitate to update, so consistent updates like the Voron-design team should be continued so that TRADRACK, ERCF, etc. are easier and more convenient multi-filament replacement tools than devices like Bamboo AMS.

6.Unidirectional clutch bearings can be printed with ABS+ etc. instead of buying ready-made ones.

that's it all. just you gonna keep head up and cross fingers!
