My start/end layer looks messy, any idea to improve?
Cura 2.4
Direct 1.75mm
Retract 2mm speed 15mm/s
Can you provide some higher resolution photos?
It looks like it may be mechanical issues…
Have you imported or created a printer profile for cura?
Layer thickness?
Nozzle diameter?
Printer model?
Try printing slower, how about sound coming out of printer, pleasant whistling or annoying machine noise ?
