[problem] Trouble printing dice

Anyone know what I need to adjust here?

  • Top Left: The scroll is on bottom, printed on top of raft

  • Top Right: Scroll printed on heated bed, no raft

  • Bottom right: This is what the scroll looks like if its on top
  • How can I fix it?
    Printer: Prusa i3 MK2 Material: PLA Temps: 1st Layer 215C / 75C 2nd Layer 210C / 65C
    (Nozzle / Heatbed)

    I would say that the top right is close to correct - looks like the center part didn't stick to the bed correctly though - did you clean the bed with Isopropyl Alcohol (99+%)? I find that works extremely well for smaller objects.
    The top right looks like it might be slightly too close to the bed, but difficult to tell from that view - it's definitely merging the lines together, but you can normally tell as you start the print.
    I very rarely use rafts as they add additional cleanup after the print. In this case it looks as if the raft settings include quite a gap between that and the start of the object which might be too large.

    You will normally have an air gap between raft and part to enable the part to be easily removed and therefore your top left image is to be expected.

    The top right is definitely too close to the bed; the lines are way too squished so you don't have a clean pattern laid down.

    The bottom right is of the side (not the top) and again is as expected.

    The concern is the top right where the higher layers have not properly bridged. As well as increasing the first layer gap, can I suggest setting your extrusion width to 0.4mm (or the same as the nozzle diameter); I think that would give better results. Also ensure that you have 3 bottom layers selected and with all layers set to 0.2mm
