Just purchased and built a Folger Tech Prusa i3 2020 kit. It seems to be doing well and I've dialed in most things but one problem. My lines are a bit wavy. I can visibly see the flow pulsate from the nozzle. I'm printing with 1.75mm ABS. This happens in all layers. I've tried slowing down print speed, and changing the extrusion multiplier higher to 1.05 and 1.1. Nothing seems to change anythingby fallsgeek - Prusa i3 and variants
