Ultimaker Original+ Under-extrusion

Recommended Posts

I built my printer about a month ago, and it has been having some pretty consistent under-extrusion. My settings so far have been:

Layer Height 0.25 mm

Shell Thickness 0.4 mm

Bottom/Top Thickness 0.8 mm

Speed 70 mm/s

Flow Rate 110%

Infill Speed 80 mm/s

Top, bottom, outer, and inner shell speed 70 mm/s

Temperature 220ºC

Bed Temperature 70ºC

I tried printing the V29 Whistle, and it has some layer gaps, and at the top, there is space between the lattice (pictures below). The whistle (needless to say), does not work. Have any of you experienced this?

Thanks,

Caleb

Maybe someone else can give you input on that, my umo+ uses 1.75mm so I print much cold. Anyhow it depends on the mm3 of filament/speed. So it's something you need to play with, and changes from pla to pla (even same brand different color). Just before of going 230+ aince pla can burn inside and make a nasty clog. Also remember to do atomic.

If your printer can print hay at 50% speed, them the problem might be somewhere else.
