Does anyone know which pins to use on a generic Prusa i3 (from Alunar)? The board is a HY_BASE_L V1.0. It has a few free connectors labeled ICSP, ICSP2, A11, A12, D11, D12. When I measured between pins 0 and 1 on D12, I saw a close when I manually emitted an m80 (through OctoPrint), but when I connected my PSU's PS_ON to it, I could not put the PSU into standby.
The board's firmware defines this board as a type 33 (#define MOTERBOARD 33).
Any help is welcome.
Thanks,
Stefan
