One thing I have noticed is the ripple is always negative material, perhaps it has to do with the density of the infill, I was using 20% or 10% on this part.

I don't know if this helps, but my machine is a refurbished UM3 from Matterhackers. Has anyone had good experience with refurbished printers from them?

Hello everyone. I recently bought an Ultimaker 3 and started making inspection kits for work. I am printing in Tough PLA with the default Cura profile. I am getting ripples (left side of block) on the bottom of the print where it meets the glass. I see it along the X axis surface but not on the Y axis surface. I get the same ripples when skewing the part 5 degrees from parallel with the X axis. Machine firmware is current and Cura is updated to the latest version. I checked my short belts and they are tight, long belts maybe could be tighter but they are the same in X as they are in Y. Has anyone experienced this type of artifact?
