sjstein 0 Posted November 17, 2017 in Strange "dots" in cylindrical slices Hello community, I created a cylindrical shape to test different parameters of my Ultimaker 2+ and different brands of PLA. I use the tweakAtZ (4.0.2) plugin with Cura (15.04.6) to change the hot-end temp every 10mm up this cylinder. I opted to print out two of them to check for stringing issues - so just loaded the STL file twice. When I began printing, I noticed an odd behavior - which I also found by looking at the layer view in Cura. The gcode doesn't print out smooth circles for each layer - it first lays down a few dots on the periphery (within the wall) and then does the circle. See image. This isn't working out very well - when the nozzle moves back around in the "proper" circle, it hits the dots and the print bed then shudders a bit. Can anyone tell me why this is happening, and how to avoid it? Thanks! Share this post Link to post Share on other sites
Nicolinux 250 Posted November 20, 2017 in Strange "dots" in cylindrical slices Hi, this could be infill (the yellow dots). Maybe the thickness of your cylinders isn't an exact multiple of your nozzle size/width. You should set infill to 0 and increase wall/shell count. Share this post Link to post Share on other sites
