The main issue I have now is that I think the hotend cant keep up with the print speed. I am not sure yet. I can extrude full speed all the way through the bowden tube without a problem, but while trying to print at that speed on the longer runs it the Extruder stales every now and then. You can hear it making a loud noise in video.
All in all I am relatively happy with the print quality, I just need to sort out a couple of minor issues.
