Don't do any modifications, it works fine, i use mine with galaad and old desktop with serial port. All you do you make the design on any pc and you load and run the file from older pc with serial port connected to the machine, there is a schematic in pdf for whole pcb, if you google it, you will find it, check images and all when you google, like search type all, and images

Thks MarMix, but i'll do it.
I don't have Galaad, and I would rather pay for a UCCNC license than Galaad.
I have the pdf of the pcb, but it does not bring me anything.
I'm looking for how to identify the wires that go from the Nema to the drivers.
