Hi...
Has anyone run in to similar problem...
When using E3D volcano with the 1.2mm nozzle, 0.9mm layer height and 1.44mm extrusion width and simplify 3D v.2.2.2 Material PLA.
All the holes become way too small like the path compensation dosen't get that large nozzle/extrusion width? My bet is that the compensation formula wasn't designed for this kind of big nozzles.
Is the Simplify 3D formula something like this? http://reprap.org/wiki/ArcCompensation
Some basic answers:
Yes extrusion width is on 0.01mm tolerance.
Someone ask printing too fast=No been printing calibrating prints slowly.
All the axis on the machine are direct balls crew driven for maximum accuracy.

Larger extruders will have more trouble with small arcs. They will overextruder more which will make small holes come out smaller than intended. S3D just added a size compensation feature that you could use. For example, if your holes are coming out 0.1mm too small, then change the XY horizontal size compensation to -0.1mm.
