@theruttmeister said in Square Nozzle Orifice:
Before that, I'd be interested to see the results of printing more organic shapes and general things not aligned with the nozzle orientation. Because:
I was printing .50mm width.
The major dimension of your square nozzle is ~0.56mm (diagonal). My interest is can you get the quality of a smaller round nozzle, but using a larger surface area and hence lower force, square nozzle.
Can you try some prints at say, 0.45mm width?
I will print some more traditional parts this weekend. I see what you're saying now. I will try it with the part pointed "forward" and at 45*. I settled on going side to side because of the ideas presented in the original post, but I think you are onto something here.
I could also make another one at .40mm for the major dim, but that seems counterproductive. A squircle would also be possible.
lol, I hadn't considered it would be ringing from the extruder. Based on my jerk/accel settings I'm still inclined to believe it's from the XY. It's throwing a Hemera around without much regard for anything at the moment.
Its an axis like any other, and steppers act like a spring-mass. I see no reason why we shouldn't be thinking about the things discussed here:

For the extruder as well.
My hypothesis being that the square nozzle, requiring less force, generates less slip in the motor and so what looks like ringing being eliminated is actually cogging of the extruder motor as it accelerates the filament (less load, less cogging).
This explanation makes a lot more sense to me now. It's definitely changed the way I'm thinking about this.
