  1. Hello community,


      I am a routine user of our Ultimaker S5. Up until now, I have only used PLA and PVA for supports. However today I switched to nylon for strength reasons (all consumables are Ultimaker branded). After changing materials, I ran Cura (v4.4) and it updated the settings within the software. I sliced my model and dutifully sent it to the printer, then went on with my day.


    After a few hours, I went to check and saw something really odd -  not only was my shape printing (along with PVA supports), but there was a "phantom" shape in the corner. A cylinder of (apparently) the same diameter of my model. 


    Going back to Cura and viewing the preview, I now see that it (Cura) did indeed make a shape off in the corner. 


    Is this a feature specifically for nylon? If so, where do I find that defined or documented in Cura? 


    If this is not supposed to happen, can anyone explain what is going on?


    I've enclosed images of the cura windows - both the model alone and the preview pane.




  2. 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?
