    I may have found the culprit:

    The plastic assembly that holds the x axis rods/motor and the Z axis bearings has hairline cracks in it.

    This HAS to be it. Just HAS to. I hope.

    What exactly is that part called? Is there a known good file out there to print my own, or is a call to ROBO best?

    Picture and we can say what you are talking about...
    The Z bearings are in the crossbar and I doubt that is what you mean.

    Almost every plastic part in that machine is printable and on thingiverse... Let's see a picture of what you have broken.

    Its a hairline crack, still seems solid, but it has to be fixed one way or another.

    You can always use superglue and see if it gets better
    That part is fairly critical since it holds the entire X axis in place.

    I'll try and print one. Wish that thingiverse file had modeling files instead of just STL, as while the profile is good for injection molding, it could use some simple tweaks for 3D printing.

    Sadly, the one Robo provided does not. Almost all of the other user contributed ones do.
    I thought @Mike Kelly had one on there: https://www.thingiverse.com/thing:729956/#files

    That had step files for everything (in the ZIP)

    Yep: X Motor.SLDPRT is in there.

    edit: mike put in a heck-of-an-effort in remodeling that whole thing for sure...

    Well, I'll make the mods and get it on the printer. Since its a low Z height print, it should turn out good.

    If you have issues shoot me a message with your file, I can ship it out to you.

    I gave up last night trying to modify that file for 3D printing, since Fusion 360 can't do .sldprt files.

    I'll take everything apart and super glue the OEM piece, see if there is at least improvement.

    I belive Mike Kelly's version of the entire printer can be opened in Fusion then you can pick the part you need and export it at .stl. I think thats how I printed my spares.

    With some experimeting I've found a way to update the 3D model imported into AutoCAD from another application such as Solidworks (i.e. if they have been further modified in the other application).

    When using the "Import" command the imported 3D model becomes a block, it now has a block name.
    While that drawing is open create a new drawing.
    In that new drawing Import the the "solidworks" model again (which has been updated).
    Go back to your original drawing.
    Use the "Viewcenter' command to update that block.
    On the "Viewcenter" dialog box select open drawings and choose that new drawing (you can choose it even though that new drawing hasn't been saved).
    Update the block in your current drawing with the new block from that new drawing.
    Close that new drawing without saving it.

    Could some smart programmer please write a macro to do the above steps with one click.
    Then we would be working with live models in AutoCAD and if they are chaged in the other application (eg Solidworks), the changes can be updated in the AutoCAD model.
    And they suggest that if you upload the SLDPRT file in the data panel to the cloud, it will convert in the cloud and be ready to use.

    I've been able to bring in and modify STL files in Autodesk Fusion 360 on my MacBook but you have to turn off the journaling (time line) feature to see the convert to Mesh->BRep menu item.

    I can't believe I missed that <facepalm> THANKS!!!!!

    It was already cleaned up for 3D printing, I made just a couple minor changes. Whomever did this, buy him all the beers!

    So while I'm waiting the 4 hours for that to print, I think to myself how else can the Z rods be wobbling? Since the pattern of the wobble is matching the pitch of the lead screws, they MUST be related. As the Z lead screws rotate, it is throwing the whole thing out of position. While this part has hairline cracks, it still seems solid. Is there anything else that makes sense why this is happening?

    Well, new X motor mount piece with new bearing, no change.

    What in the WORLD is next?

    ETA: And now the wobble is on both X and Y axis. Got worse, actually.

    That is very odd. Can you look at your middle plate( whateverything bolts to) is it cracked or loose? Kind of at a loss without being able to look at the machine hands on ya know. lol. I cant imagine what would be causing all those issues, but if X and Y and Z are all doing it there are only a few things that involve every one of those things. 1: Middle plate that everything bolts to. 2. hotend being loose(affects everything) 3. Ramps/Arduino issue 4. Slicer issue (maybe)

    I honestly cant think of anything else that may cause the issue?
