Gday All,
Ok since 3 days ago all my prints off either extruder are nowhere near as smooth as previously, yet have changed no filament or settings..Any suggestions ?
Secondly both extruders have build up of black ? on outside of them, could this be affecting my heating / cooling which in turn is affecting print quality.
Thirdly have noticed if printing a vertical tube, there is an uneven seem the entire way from bottom to top in one straight line ??
Have no idea whats happened
Steve
