I have had my Ender 3S1 for a year or so. I use it occasionally. Today I just cannot get it to print right. I am using creality filament through the normal head. I use Cura as my slicer. I am trying to print a 15mm diameter disc. What it looks like to me is that when the printhead gets to where it wants to start printing, there is a delay in the filament being extruded. So it starts to print the circular wall but no filament comes out for the first half of the circle. Is this delay normal? If not how tomI rectify it? Thank you for your help. Chris
