I am going to run just about every material I have in stock through the R2 and see how they all look. Up first though is a Cura spliced test on something I have printed hundreds of, so it is a file I know well and oddly one that Cura has never done well on. Essentium PLA 215 Nozzle, 60 Bed More images can be found here - https://www.dropbox.com/sh/l2lkkr9h4v3kw9c/AAB2w-jXSKqCTSnZyQqYB2qVa?dl=0 (Dark Blue is Essentium PLA, Grey and Red are Matte ProtoPasta, Black is HTPLA V3 ProtoPasta, Light Blue is MakerGeeks PETG - everything other than the Essentium were printed on a FlashForge Dreamer at the same layer heights, speed is within 5mm/s on both machines) I am seeing something that I would call stepper ringing, not sure if this is Cura or the machine yet. For the material tests I will run some sort of cube or object. Might run one each with Cura and S3D - will post more pictures soon. Edit: wanted to also point out I am seeing some really minor changes in the layers, in the light it almost looks like the X/Y is shifting(belts), could also be extrusion temp I guess. Or it is Cura!
