I think I found my extrusion issue

I took apart my extruder today to see how its going, and it not going well.

So it looks like a bearing was missing on the idler axle here, and it caused some uneven torsion that ended up cutting a notch into it. I ordered up some replacement parts, and found that the original parts I got were really sub par. The new hardware has much better teeth on the filament contact. We’ll see how things go.
