Hello,

i have a hictop i3, and have been printing for quite a while with great results. It was only until yesterday I put a 9 hour print on my printer and by the end I was having underextrusion and the small circles (screw holes) were not round at all! (But large arcs are perfect) I have tried tightening my filament holder, increasing the extrusion multiplier, and slowing down the print. My belts seem tight and I have never had an issue with missing steps before. I’m really stumped and could use some help with ideas on what I need to do to fix it.

Hello,

Maybe you can try to do a layer start on a random point.

Hope it help
