    Anyone have any ideas to what could be causing this. I can print a perfect XYZ cube with no issues or problems.

    However, my prints keep getting random layer shifts on larger prints. I even slowed my print speeds and still the same issue. Heres are a few examples. The one picture with the raft was a total mess. the first bottom layers were not even on the raft?

    Ive been printing with PETG and here is the settings in Simplify that I've been using? I have a E3Dv6 hotend.

    Check your belts and timing pulleys. Something mechanical could be loose

    That was my thought but Cant seem to find anything loose. All my pulleys seem pretty decent?

    Can someone show me a photo of where the 2 each pulley set screws are for the X & Y? I was told to check them by tech support but not sure what they are talking about?

    if you look at your belt you will see the pulley the belt drives on (shiny). there are 2 set screws in that pulley( not in the teeth section).

    this is a similar pulley, I dont have my machine with me to take photos at the moment but there are two of the little black guys that an allen wrench fits in. you want to check x, and y.

    You'll also want to check the belts on the axis that is showing the issue and make sure its tight enough. The x belt will make a twang sound not a thud when you pluck it

    All of mine only had one set screw so don't be shocked if that is what you find.
