we made some circuit bored or the first time on the other mill. It was very satisfying. Starting we made a beak out bores to connect our 8 limit switches to a IDC 16 pin ribbon cable. We made a 4 stepper to IDC also. we got the tool and made the cable our selves and it was relay fast with no soldering.
we used KiCad to make the circuit.
total mess at first.
