Under extrusion of small perimeters

Recommended Posts

Posted · Under extrusion of small perimeters

Hi, I've been having some issues with a particular print due to under extrusion of small perimeters that are extruded right after the thin lines (thinner than the 0.4mm profiles for my nozzle size)  that seem to fill small gaps in the top surface (I'm not sure exactly what these are called). It seems that right after the extremely thin lines are extruded and retraction occurs, the outer walls are under extruded for a short period of time(which is enough to entirely weaken smaller perimeters). Any solutions? Thanks.
