Flashforge Creator Pro Extruder Block Upgrade for Flexible Filament

[jfkansas]

The tolerance between the filament drive gear and plastic is much tighter. The filament is fully supported after the drive gear.

The stock plastic is 4 pieces, and 3 screws. This design is 2 plastic pieces and 1 screw. I also beefed up the preload on the spring to have more pressure on the flex filament.

There isn't any PTFE in the feed mechanism.

Thanks for your explanation.

What do you think about including a wire brush to continuously scrub the drive gear?
