What to do with stock print head if upgraded to INDX
I will be getting a Prusa Core one or Core One L. I will be upgrading to the INDX system. My questions is, would it be easy to use the stock Core One print head on another non Prusa printer? I have a couple older printers, and even have one running klipper. I can figure out the mechanical part of mounting the print head. What are the electronics like? Is this running a CAN bus? If so, does a CAN board exist that I could buy to integrate the print head? I am assuming that the whole Prusa extruder and hot end is replaced with INDX. It would be a shame to have a quality print head go to waste, especially since it is probably superior to what I have on my old printers.
Thanks for your help fellow polymer squirters.

RE: What to do with stock print head if upgraded to INDX
The Nextruder does not use a CAN bus. It has analog readouts for the two temperature sensors, PWM control and tacho signals for the two fans, and the chip-specific serial protocol for the HX717 differential amplifier (load cell and filament sensor). Switched/modulated heater power is provided by the main control board; connections to the stepper motor windings go directly to a Trinamic driver chip on the main board.
With the exception of the filament sensor, it's all pretty conventional, so the Klipper firmware should offer suitable drivers. But you will need to find matching available ports on your control board. Prusa has published the schematics if you want to look into connection details. The "Loveboard" is what you want to look at, that's the small PCB which sits directly on the Nextruder head.
