That’s the exact failure that happened on the bend test for Zak on JerryRigEverything. Crazy it’s happening without the full-muscle stress test.

I get he’s a 3D printer beginner and it’s not really his thing, but I wish he’d learn which slicer settings to adjust!

Potentially rig up some PTFE tube holders that stick to your wall to ensure the filament enters the AMS motors’ yellow areas at a perfectly straight angle, I bet the filament is just getting “sticky” with any drag on those parts.

That’s a really cool upcycle! Nice!
