My A10M performs beautifully until I attempt to print part(s) with separate vertical areas. At which point the stringing that I get from the E0 primary side (left side) of the hot end is horrific. The E1 side (right side) is pretty much perfect. That is in real world use as well as toggling from extruder to extruder with the FW mixer within the same exact print with the same exact settings. I've tweaked the print settings over and over again with little to no improvement in the E0 performance. I've also ruled out potential differences in filament by swapping one roll from E0 and E1. I've cleaned the hot end numerous times with "atomic pulls" etc. and the nozzle is not clogged but has been changed as a precautionary measure. The truth is with the E1 side working correctly it really rules out a lot of stuff.
So, that has led me to try and diagnose a mechanical difference in the E0 and E1. With the OEM extruders I could hear a difference between E0 and E1... it sounded like E0 was just working harder to push/pull the filament through the bowden set-up.
- That led to my first purchase of new PTFE tubing and couplers. I ordered enough to do both sides and installed the new set-ups without realizing any change in performance.
- That being the case, I began working on the extruders themselves... took them apart, cleaned them, lubed them and reinstalled them. No change.
- I then decided that I would order and change out the OEM extruders with dual drive Bondtech clone extruders. Just go them installed and absolutely no change.
