Print speed (mm/s): 50

Support

Support type: None

Platform adhesion type: None

Machine

Nozzle size (mm): 0.4

Advanced

Quality

Initial layer thickness (mm): 0.3

Initial layer line width  (%): 100

Cut off object bottom (mm): 0.0

Dual extrusion overlap (mm): 0.15

Speed

Travel speed (mm/s): 150.0

Bottom layer speed (mm/s): 20

Infill speed(mm/s): 0.0

Top/bottom speed(mm/s): 0.0

    You have underextrusion. What material is this? PLA? Usually PLA doesn't peel off like that but that's common with ABS and easily fixed.

    Still - what material is this and what temperature (temperature is set on the printer, not in cura).

    I think the default temp is 210C and assuming PLA and with .3mm layer times .4mm nozzle times 50mm/sec that equals 6mm^3/sec. That's a bit fast for 210C and PLA. Try raising the temp to 220C and making your layer height thinner - try .15mm also slow it down a bit to 35mm/sec. That should fix much of the quality problems.

    I used a PLA not ABS. I try your settings.Thank you
