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?
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.
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?
