Hey all, So I've got 2 issues left with my C2, one of them new. The new one is this weird jamming issue I've been having just lately. A print will fail, looking like a jam or filament break. I check and the filament is ok, and when I push down on it into the extruder it feels like it's hit a wall. Then with a little pressure it breaks through and extrudes fine. What the hell could this be? I've already printed a replacement carriage so I can replace the stock hotend with a spare E3Dv6 I have laying around, but I haven't gotten around to it. This may be what I have to do. The second issue I've had ever since my first print. Random layer shifting. I'm having to print at 40mm/sec and move at 80mm/sec. I've aligned and properly lubricated the hardware. It still freaking happens even at that slow speed. What could be causing this?
