Upgraded Max Z Effector (Inductive Sensor, 30mm Fan and 30mm Blower/Part Cooling) by JAW

Last crawled date: 3 years ago

Description: The JAW Effector improves print quality by raising the hotend nozzle closer to the plain of the effector's arms. This isn't a unique idea, but my design is smaller in diameter than other designs that utilize ball ends. The result of this compact effector is improved print accuracy, while still maintaining the original build volume of a Kossel style delta printer.
Testing: Final design tested 2/27/18 without any clearance issues on my homebrew Kossel Mini delta printer using Traxxis rod ends. Works like a charm!
Hints for assembling perfect traxxis rod ends: First, glue the carbon rods to the rod ends using a printable jig found on Thingiverse. Then, hold the rod ends in a shallow pot of water at a rolling boil. After submerging the rods for 10 to 15 seconds, squeeze the circular holes gently with pliers (they should bend under pressure and seem to return after you stop squeezing). Next, push the balls into the rod ends (make sure to do this on the correct side of the rod ends, one side has a larger lip and the other has a shiny ring around the opening). If done properly, you will have zero play in your effector's arms 100% of the time (no throwing out ball ends that are loose after assembly). If you assemble a ball end that isn't tight, gently remove the ball from the rod end and repeat the assembly process again to correct the issue.
Print Settings:
-Print in PETG (or you can use ABS). Regular PLA will not withstand the higher temperatures around the heater block.
-Print with supports for the main body of the effector (under the radius/curve of the hotend arms so they print well and to support the center column of the effector where the hotend will go. The hotend clip will not need support.
Hardware:
-You will use various M3 bolts and will also need an extra m3 nut (besides the 12 for the effector's arms) for the inductive sensor holder.
-The effector is designed to be used with one 30x30x10 axial fan to cool the hotend, as well as one 30x30x10 radial fan for print/part cooling. (You can find these on eBay and sometimes on Amazon when they are in stock. They are 5-volt fans, which is perfect for a Duet board).
