I’m trying to print something artistic, so I’m trying to print really tiny features with a 0.2mm nozzle. I see that I can set all the extrusion widths to 0.25mm. So I figured that if I made a feature in my STL file that was 0.25mm wide, then I’d get a line in the slice. And that does seem to work for things that are at least 0.5mm long. But for 0.25mm x 0.25mm dots (which I need to print the right shades), they disappear entirely. Now, I realize that there’s no way the printer can be perfectly precise, but if I got a gap infill dot, I’d be happy with it. Any idea what settings I need for this?
What settings are you using with the 0.2 nozzle? Maybe your walls would be too think for the print to work. If your walls are 0.16 it woudnt be able to make a full circle as it would too big for the boundaries i think
Interesting. I would have assumed that a 0.25 dot would not be a problem with a 0.2 nozzle. At least in the slicer. Practice may be very different as the extruder needs to feed at least a single microstep (which I expect would be even lower though).
Does it help if you set the wall generator to “Arachne”?
Arachne doesnt help below 0.4 mm from what i know… Makes it worse.
When arachne is applied to walls, the line width of wall may be various rather than fixed. And then it’s difficult to calculate how much percentage of width of the wall extrusion line is unsupported.
Well, technically, there are no “walls.” I’ve set the wall loops to zero. This way, I should get just a little dot for the 0.25x0.25. I had arache on. I’ll try turning it off.
I did try setting the line widths to 0.125, and that managed to not lose my 0.25x0.25 dots. It turned them into U shapes. However, I don’t know how well this will work. It might do okay since the layer height is 0.04mm. Or it’ll mush everything together.
No worries. From my understanding of Arachne, it is related to the nozzle diameter. I think I remember it being mentioned as giving an adequate performance down to 60% of nozzle diameter but I expect that heating chamber volume, speed/flow and extruder limitations may come into play as well.
