I am having a problem with Cura adding brims on all quality levels. As the brim gets closer to the center, the nozzle isn't moving far enough per loop, so about halfway through the filament is jamming (even with a nice gearhead extruder) because the nozzle is completely covered by the previous loops and it's squirting out the sides. I can't seem to find any Cura settings to adjust the first-layer line width, which would hopefully influence the spacing of the loops. I set the nozzle diameter to 0.3mm, which is according to the Printrbot Simple specification on their website, and if I don't use a brim the print comes out nicely, if not for the curling... Help please?
I have most definitely set the nozzle diameter correctly, I believe that Cura does not account for the increased line diameter of the first layer due to squishing onto the plate for good adhesion. I cannot raise my extruder any higher because the filament will not stick. I think it's a software problem, it's not accounting for the flattening of filament on the build plate while advancing toward the center!
I have also tried fiddling with the extrusion multiplier, but it just makes the loops have ragged edges and when it finally gets to the model itself, the lines are too thin and the layers are not sticking together. I have no printing problems with PrintrBot's cloud slicing, but their brim functionality is broken so I thought I'd try Cura with the manufacturer's recommended settings, which brings me to the problem described in this post.
Please Help!
