TAZ 5 with E3D V6 I am having many problems lately. I got my configs back to normal by flashing the firmware but while testing for extrusion calibration I noticed that when it first starts extruding (for say the first 10-15mm) it comes out real fast (like it use to) but then even though the gear is spinning the same speed the extrusion looks like it slows down quite a bit. (the idler is tight).
Now, I have had several bad jams in the E3D and I am wondering it either plastic on the inside of the heat break tube or fine scratches in same would cause this?
I took my entire extruder apart, made sure everything was fine, took the hotend apart to do the same and even put on a brand new nozzle and did the whole test again and it came out the same. If I push the filament in by hand it seems harder to push than it use to with the Hexagon hotend and the Buda style hotend and all this with a .35mm nozzle.
I also stuck a Fluke temperature probe down inside the filament path all the way to the nozzle (the probe is round stainless and the exact same size as the filament so it’s snug all the way down) and it shows at 245 the temperature is low but only by 2 degrees which I think is fine.
