must calibrate extrusion rate
This has nothing to do with extrusion rate. It is intersecting 3 lines on the same layer. The extrusion rate is correct.
The only way I see around this if you want to use triangle infill is to make it print each side of the triangle pattern on different layers. So, it takes 3 layers to complete a pattern of triangles. There is a check box to make this happen.
If they wanted to print the complete triangle pattern on one layer, the extrusion needs to stop when it is intersecting or something, but it does not seem to be setup for that. The second and third lines making up the second and third sides of the triangles, just rams through the previous line where they intersect. You basically end up with 3 thicknesses of extrusion smashed on one layer where the 3 lines intersect. When it does this you can hear and see the vibration/stuttering sound as it hits the intersections (on the second and third lines of the layers infill).
