    While prepping for some usage today I noticed my Z was really loose.  I discovered that the part cracked so the bearing was loose.  There was one strand of PLA holding it from falling off completely.  I am trying some epoxy to repair it, but this might be an opportune time to upgrade to the newer parts (I am running the older style MPCNC ).

    Originally I purchased all of the parts from here, but I now have a 3D printer so figured I could print the new parts.

    My question is, what are the parts I need for a new middle assembly?  I have the 5/16 “lead screw”, and 3/4 EMT conduit rail.  I get a little confused with all of the parts and want to make sure I print the correct ones.

    Also, I just recent finished printing a bunch of tool mounts based on the Hicwic quick change mounting system.  Is there a version of this that works with the new middle assembly?

    Thanks

    You need all the center and z axis parts to upgrade. If you get the chance the new rollers are a big upgrade as well. Keep that printer busy! On the C versions you can keep the same corners and feet. The other two versions I screwed up and it is best to change the corners as well (they are off by a little more than a mm….not huge but still).

     

    There is a hickwic for the new one, I am not sure if the mounts are interchangeable between them. I doubt you will use it though, the newer mount is way easy to swap and it is more rigid that way.

    Thanks, I did notice that the rollers look much nicer.  I have a few of these that cracked and have been repaired as well.

    Are these all of the middle parts with only the nut lock that is appropriate for my z-nut?

    Also, what infill do you suggest for the parts?

    I am almost tempted to re-print everything for the stainless tubing.  I have access to some stainless conduit “drop” that I could use.

    You have to measure your znut to know, I have shipped both. The infill is listed on the parts page.

    You also need the XYZ parts.

    Had another bearing break off my old middle assembly so I am making the jump to the new middle assembly parts.  Question I have is regarding the XYZ part.  I have the 5/16 threaded rod but the XYZ part has the T8 in description.  Will this still work with the 5/16 threaded rod?

    Yup
