This is great. I don't see how I can resist making one. I will probably 3D-print the hardware but use my own electronics and SW for controlling it. (I'm kind of addicted to writing my own software for controlling 3D printers and this looks like it would be an easy fit)
I suppose it's a stepper motor that needs to be moved to the right position? How is it homed?
The sensor is mounted on a PCB that can be physically shifted to apply minor adjustments to the home position. The adjustments could easily be done in software, but doing it physically "stores" the adjustment parameter for each module without having to reprogram the controller.
