Hot End Effector Setup for Cherry Pi III with 10 mm ball bearings (Or 8 mm balls) by maso27

Last crawled date: 3 years ago

Edit 5/12/2015: I updated "Z_Probe_Effector_Just_the_Spring_Mount_End" with a "repaired" version. Nothing has changed in the design.
Edit 12/4/2014: I have added 8mm versions, so that there can be a straight-across replacement for the current Cherry Pi III setup.
I Rebuilt the end effector for my Cherry Pi III to use the sprung-string approach.
I opted to change my 10mm magnets out for 10mm ball bearings (instead of the pre-drilled 8mm balls implemented originally), and made some other changes.
I can verify that this just fits an E3D Mark6 fan and clip below the platform. There are new holes for the springs on the J-head mount, as well as two corresponding holes on the platform.
I also moved the hinge for the rod carrier to the top of the carriage, giving back most of the z-height lost by moving to a top-mounted effector design. This is done by flipping the mini V-wheel mounts upside down. The holes then line up.
Also, note that the diameter of the balls, or many other measurements, can be edited within the OpenSCAD files to adjust them as necessary. So a version with 8mm balls can be used as well.
