Topic: Problems with ABS feeding once again.
Thought I had the ABS feed problem fixed. Turns out I was wrong. Before I started, I took the entire print head apart and made sure it was clean with no blockages or blobs of PLA in it.
Put it back together and videotaped the priming of the extruder.
Sorry about the blur, my camera phone couldn't focus right.
Note that there are index markings on both the toothed feeder gear and the bearing, so that you can see when it is and isn't turning.
When first started up, the toothed gear turns, but not the bearing, I didn't have it set correctly to feed.
Once I get it feeding, it took 150 mm of the filament to (1.60 mm) to get any filament to extrude.
Notice that the bearing stops turning, at which point I tighten the feed tension screw. This helps for a few moments, then I have to tighten it again. Eventually I have it as tight as it can go.
Please also notice that I have to manually push the filament down to get it started again.
I have no idea why this is occuring, as the feeder works fine with PLA and PP.
Any help will be greatly appreciated.
