ABS Rough Edges in Z Axis


Hi All,

Any thoughts on the issues in the pics for ABS + ? I’ve tried the standard Bambu ABS+ profile and the esun ABS + presets (it’s esun).

Tried turning cooling off and slowing the print down and get approximately the same problem replicated each time.

Layer strength on the larger curved section is very impressive given it’s 3mm thick and there’s no signs of under extrusion there.

Should note nozzle is 270, K factor is 0.22 (based on manual calibration), flow is 100% and bed is 90DegC
