Hi,
i have one problem that i couldnt solve since i started printing parts with my Prusa I3, the objects always have a gap where the printhead raises to the next z layer. i think it could have smth to do with retraction but i'm not quite sure if this is the problem. Retraction is set to 4mm at 40mm/s. any solutions on this? (see also pictures, left side everythings okay, on the right side is where the printhead raised i have this ugly gap)
