Hey guys, I've got an E3Dv6 Chimera, and I've been having a lot of issues regarding extrusion, for whatever reason it seems to only want to easily extrude PLA at temperatures of 220c, I am able to get it to extrude around 200c however it results in significant under extrusion at higher layers when the fan kicks in. I have yet to do a PID autotune because I've attributed a majority of this to the fact that my resistance in the firmware is wrong, it leads me to believe the temperature readouts I'm getting are well off (or I could be wrong). I wanted to clarify if there's a recommended value for this. I've read through the E3D wiki and I found the values to enter, but those don't seem to be proper. I've never used the chimera before, so, in your own experience is it normal for them to under extrude at 200c with PLA? I wouldn't think so but maybe I'm wrong. Anyway, any help with this would be appreciated.
