Very interesting project :)
Do you know if it is possible to get 3.3V somewhere inside the MaraX? Since the power consumption of most ESP8266 based boards is very small, it would be very convenient to use it without an additional power adapter and just pick it somewhere. Especially if considering to use the very small ESP-01 board whith Wifi, the "extras" can stay inside the MaraX.

1. I don't think there are prefered variants, as long as it has an esp8266 the code should work
2. the oled displayed used in the wiring diagram, is a diagram, that was the one I used to show the wiring. ofc, you need to use an oled display tha tis compatible with the 3d printed case. as long as it has i2c any oled display should work
3. I think it's normal open

I'm not sure, where you can get that power from.I did not search, because I didn't want to risk damaging the electronics of the machine.
