Automatic Tangle Cutter for ACE Pro

This is most definitely a work in progress.

I have an Anycubic Kobra S1 Combo, with the 1st generation ACE Pro. I have very few problems with the ACE Pro, but one recurring issue happens when I have backup spool enabled, and a spool runs out that has a bit of a hook or kink at the end of the roll. The kinked filament has a tendency to jam the extruder, which both interrupts the print and forces me to remove the nozzle and clear the jam. I tested this several times by starting a print and cutting the filament cleanly before it enters the ACE. It didn’t clog when I did that. Putting a small kink in the end after cutting caused clogs about 40% of the time. So, I wanted an cutter I could put into the ACE Pro, and thus this project was born.

This project is heavily based on the work of Дмитрий Воробьёв (Dmitry Vorobyov). I found the design on printables here: https://www.printables.com/model/1649825-automatic-filament-tangle-eliminator-passive-filam

I have made several modifications to better suit my needs and preferences, but the mechanism is virtually unchanged. That said, this is a work in progress. I have plans to make a version that uses a metal spring, assuming I can find one that is both strong enough and small enough…

I would also like to credit whoever made the ACE Pro ledge profile that includes a hole for the light. I’ve seen/printed so many projects with this profile, it seems wrong to single out one person when I don’t know who it was that actually developed it. So, thanks to the community for that.

NOTE: This device requires you to remove the “fins” attached to the lid of the ACE Pro. This has caused no issues for me, but your mileage may vary!
