Can anyone explain to me why I'm getting regular over-extrusion patterns on this extrusion calibration cube?
Just upgraded the extruder from stock to Flexion HT on my Balco Touch (Wanhao i3 plus) and now I'm getting a strange pattern on my prints.
The photos below show me trying to calibrate the extrusion multiplier after completing the extruder install. The first is with a factor of 1 and the second with an adjusted factor of 0.86 (which I suspect is the reason for the change in pattern?).
I guess this is some kind of mechanical issue causing the over-extrusion? Any ideas?
Note: during the second print (below) I was playing with the Flexion extruder's Cam set screw hence why it stopped extruding all together. I tried it set tight and loose and other than when really tight and stopping the extrusion there was no real difference in the pattern when extruding.
