My PrintrBot Simple Metal has long suffered the dreaded Z WOBBLE ! I have seen others postings of their solutions to the problem, but they all seem to miss the same contributing factor that PrintrBot themselves missed from the beginning, the free floating end of the Z axis lead screw.
I decided if I was going to fix the problem of wobble, I also wanted to upgrade my printer from the 1/4" imperial lead screw with a single thread, to an 8mm trapezoidal 4 thread (4 start) lead screw and reduce the rotation my Z axis stepper made per unit of vertical movement.
I am a fan of embedded nuts for mounting hardware, and my lead screw guide nut mount includes them. For those who do not like embedded nuts, I would consider them in this application, because if threaded plastic fails here your entire print head will come crashing into the print bed. The guide nut mounting holes can accept up to 3.5mm hardware, but I was not able to get the nuts to fit due to the collar size of the guide nut,
