Stepper Splitter Box - Dual Stepper Z Axis
Description
This is a splitter box to split the stepper drive output to a dual stepper system. Steppers can be connected either in parallel, or the preferred serial connection (as I show in my build). This uses common JST-HX vertical pc mount connectors. This is based on the cable method described in Instructable [https://www.instructables.com/id/Wiring-Your-Z-Stepper-Motors-in-Series/], except substituting female connectors, making a cleaner installation. I used a piece of standard perf board I had laying around, but a board can be printed using enclosed file. When assembling, I found it easiest to install connectors into cover first, then overlay the board for soldering. This makes it easier to solder, as parts are in correct position and are fixtured. Note that the board is not symetrical, so use caution to make sure parts are in correct position before soldering. Base is modeled with M3 threads, but I always run a tap through to clean threads before assembly. Assemble with two 15mm long M3x0.5 screws
