    Reassembled my hexagon and everything is tight. Print speed is 50mm/s. Happens with ABS and PLA. The attached photo is rotated 90 degrees, so I feel confident that the odd ripple effect is on the x-axis.

    Any idea? I know print speed can affect this, but I've printed at 50mm/s before with no issues.

    Hi Geof - thanks for the quick reply!

    If you look above the hole, you can several "waves" in the shape of the circle. This can also occur in straight line across the x axis as well.

    My first thought is something is slightly loose. Check the belts to verify they are tight. Oil the threaded rods while your at it (pm work is good). Take an allen and ensure the pulleya on the steppers are tight and we can go from there

    Ok, I will check that out. I oiled the threaded rods during re-assembly and the belts felt OK, but didn't think to check the pulleys. I will,let you know what I find! Thanks for your help.

    Your welcome keep me posted. The x belt should twang when you pluck it not thud :)

    Also. If you have the R1+ with the z stabilizers make sure both z rods are in their slots.

    Maybe try slowing down your acceleration settings?

    OK, I checked the pulley and was able to tighten the set screws about an 1/8th of a turn. Checked the belt and it kind of twanged, but I seem to remember it being slightly tighter when I first received the printer. It makes sense that the belt can stretch over time, so I printed a cool belt tensioner that worked pretty well (maybe a tad TOO well, as I used it once then took it of for fear of messing something else up). I've been printing wire chain links, so I hadn't had a chance to check the rippling until I printed something larger last night and the problem appears to be resolved now, but I'm going to try one more part that might replicate the issue.
