I did not see a general thread where people could ask for advice on print settings so I posted this thread.
I am printing with ABS with a heated bed and enclosure (Prusa MK3s). When I print single objects everything goes fairly well. However, whenever I print multiple pieces at the same time I get bad vertical ridges and gaps -- I think this occurs due to the print head changing between parts. I also sometimes get strange spirals of blobs on nose cones - one blob per layer (you may be able to see this on the nose cone in the pictures but this is pretty subtle compared to what I often get). Note: Notch on edge of shoulder is in print to help with alignment on body tubes.
.4mm nozzle, .2mm layer height, 2 external perimeters, 5 top layers, 4 bottom layers, 15% rectilinear infill (most shells are around 3 layers thick), seam position = nearest, external perimeters first (I think this is the issue but when I did not set this flag on I used to get bad outer surface variation / irregularities due to changing shell thickness I think). Speed 45mm, small & external perimeters 25mm, first layer speed 25mm. I can share more settings.
Here is an example of something I printed alone on the bed...
I have just been sanding and filling parts but would love to get my setting dialed in a bit better so that I do not need to do so much cleanup. Thank you in
