I’m not worried about first layer height. this was a test of temperature I was doing. there is noticeable over extrusion on the corners, that’s what I’m trying to figure out. I’ll get the bed level when I get the thing printing right. And the ripples are from the zinc I’m still wearing off. if you notice they are in the exact same place at each layer so it’s a deviation in the movement across that axis and i can hear the pipes grinding when the ripples are being drawn.
