Greetings!

Been using the ERCF / ERCP for I think like 9 months or so and the StealthBurner / ClockWorkd2 on my Voron 2.4 since it was released to the Public with my own MODs to make the CW2 ERCF compatible.

Two exhaustive printing weeks must have worn down my Beta 0/1 CW2 Toolhead Parts down to the point where - I assume - The Guidler and/or Latch may have gotten bent out of shape just enough for the Gears to not be digging in enough anymore to overcome the always present friction in the ERCP > ERCF > CW2 Filament Path thus resulting in frequent Filament Grindings and failed Prints - With the necessity of printing new parts I decided to give the recent CW2 Beta 7-11 Parts a try which turned out to be even worse but while I was it I went ahead and traced the cause of the friction back to the off tangential Filament Exit Port of the ERCP:

Basically... Whenever the Filament was stuck and ground to an Hourglass shape in the Toolhead I checked where it may have been stuck by pushing it back but couldn't feel any resistance but pulling it beyond the point where it became stuck was almost impossible.
Taking the Buffer Zone out of the equation would mostly solve this so the issue must be there ( my wheels are spinning freely and the Spools too have been placed on bearings.
For the time being I've resorted to not be winding the Filament onto the wheel and instead just use two PTFE Tubes with one connected to the ERCP PTFE Entry Block and the other to the ERCF Filament Block causing them to split apart if the Filament is being retracted and butt together when the FIlamen is being Extruded.

I'll probably do a DIY MOD of the ERCP to see if this can be solved by printing a Buffer Cross with the Entrance / Exit ports pointing perpendicular towards the Wheels Inner Diameter and thus not introducing that kink in the Screenshot.

I've also noticed certain Filament having a tendency of liking to get pushed out between the rear and bottom Cross sections thus spilling outside instead of coiling up inside - Maybe a wall connecting/closing those two could help with this? 🤔
