1mm profile for Slic3r PE for MK3
Having some trouble getting good results on my Prusa MK3 with a 1mm Stainless Steel nozzle(short stubby) i bought off of amazon.
here's some pics after testing a 20mm test cube
printing with a 0.5mm or 0.4mm nozzle prints just fine for me. but using a 1mm nozzle seems to give me problems with delamentation, mostly on the top solid infil layers and bottom solid infil layers
perimeters it seems to do fine with on this cube.
layer height is about 0.7
speeds ive tried 50mm/s and 30mm/s
for extrusion widths ive tried various combinations between 0.95 - 1.25
here is another failed print of a slightly larger object with some various angles. this object prints fine for me with a smaller nozzle.
as you can see, it has many problems.. including the skirt coming loose and getting trapped into the object.
Im wondering if anyone has any experience with 1mm nozzle's and could provide me with a profile or screenshots of their slic3r PE settings?

Hi,
your problem is most likely the volumetric flow. Your hotend cannot get the material hot enough to melt to the printed object. I plotted the flow for the standard 0.4 mm nozzle and your settings (1.00 mm extrusion width) at 30 mm/s and 50 mm/s.
At some point, Josef Prusa stated that the E3D hotend can handle up to 15 mm³/s. In order to stay below that threshold, you have to:
- reduce your layer height accordingly, or
- go way slower, or
- upgrade to a more powerful hotend

Re: 1mm profile for Slic3r PE for MK3
What slicer are yiu using? Slic3r is the only one I've found that allows setting a max volumetric speed that will automatically limit speeds based on nozzle size, extrusion width, line height, acceleration and other factors. Set a limit for your extruder (I used 11.5) and it will ensure your printer will keep up. At 1mm, speeds will be very slow. I had some luck with a 0.8mm nozzle and 0.48mm line height. I suggest starting with lower layer height and work up as you have success.
