Hi folks,
I am having some strange issues with the g-code from the skirt/brim generated by Simplify3D when the extruder pressure advance is active. On round corners and circles, the movement is extremely slow, sometimes when the outline is really complicated, it takes ages to complete. Once it gets to the g-code of the part itself, there are no issues there, no complains. If I issue a M572 D0 S0 during the skirt printing, it returns to normal printing speed.
I noticed that the only difference in the g-code of the skirt/brim is the fact that it contains a lot of small movements with extremely small extrusions, like 0.0005, sometimes even 0.0001:

Can someone test this? The only workaround I found is to manually edit the g-code and deactivate the pressure advance at the beginning of the skirt and activate it back when it starts printing the part itself. Any other solution ?
Thanks !
