1 I had read so many good things about the Bowden extruders I thought I would try one.
2 I bought an e3d hot end and new all metal extruder parts with a new drive gear.
3 I played with different settings for five days and could never get the filiment to feed right.
4 The first half of the print would go just fine...
5 By the time I got to the second half of the print the extruder would start skipping and grinding and of course the under extrusion ruiend the print.
6 I would pull the filament out, trim the end, and put it back. I could push it through the hot end by hand with no problem.
7 I tried everything, new tubing, hot end temp, flow rate, feed rate, new fittings, nothing worked. I finally went back to the direct drive and have had no problems since.
