Would it be possible to add modular control of multiple ESP32 modals?
Adding this would possibly create a timing issue but would allow for distributed I/O and allow for tool changes with an independent ESP32 module for each tool (print heads/laser/spindle ect.).
A dedicated network would probably be ideal.
Axis could also have independent controllers allowing just power to be run, reducing the number of wires/cost.
Defining these in config.h would be an IP address ideally.
I look forward to hearing your ideas.
