I just got my second UM2 last week. My first one doesn't skip and I run it at 210C default w/o an issue. On my new one I have a couple of issues including this one. My older one I can run .1mm layer at 60mm/s w/o an issue. With the new one I have to run it at 50mm/s with a layer of .15 or else I get skipping and under extrusion issues. I've done the atomic pull cleaned the nozzle but it still doesn't run as well as my 1 year old UM2. My second issue is the long screws that hold on the had don't fully tighten. The back left screw sticks up almost 6mm. The hole is tapped but it still doesn't fit. I can't believe it made it to shipping with this obvious flaw.
