Flashforge Creator Pro Extruder Block Upgrade for Flexible Filament

What are the mods on this?

Sorry for the blurry pics...But should give an idea on how they end up.

ALso have you wedged the tensioner lever open/down ?
That was all i had to do on my creator.

That said - green ninjaflex works great - red, not so much.
In fact our of a half dozen flexible filament samples - I've never got red filament to work properly. Green is the best, and white seems to work okay as well.

I ran the same file in Black and Red and got similar results. I think my settings are at 60mm/s also, however due to accceleration curves and the small part size I doubt it gets to that speed. Outlines are set to 50% speed also.

What do you mean by mods? The black plastic is all different than the stock plastic.

I am interested to know what you changed.

Did you somehow move the feeder gear closer to the PTFE tube, for example?

I am not familiar enough with the stock configuration to see what was changed.

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?

It really isn't needed, I don't clean my drive gear but about a couple times a month at most. I usually run a #11 xacto knife down the grooves, not a brush. Sometimes a quick blast of canned air is all that is needed. It would also take another perpendicular drive system since you would want to brush along the grooves and not across.

Yeah, ideally it would be along the grooves, but with a continuous action, across could be effective enough.

Might be better than taking it apart a couple of times a month.


Then again, if the brush were round and mounted at an angle and allowed to rotate, it could have significant across the grooves motion propelled by the gear motion.

You gotta check out my extruder mount. I can have a stepper out gear cleaned and back ready to roll in a few minutes. If I really tried I bet I could do it in under 3min. lol
