Extrusion values for high layers are too low #16

Closed nguyri closed 5 years ago

Fairly sure that some compensation is in place for fixing the extrusion lengths for higher radii, but it doesn't stop the layers from separating at around 20+

nguyri commented 5 years ago

This can be confirmed by comparing rings at layers 2 and 20, the extrusion values are both around 15 where the extrusion value at layer 20 should be 1.5x, also it can be seen nice and clearly in Cura! At least that makes debugging easier

Simple enough problem, didn't actually add z to the drum_radius when doing the extrusion calculation
