If there is a choice, I prefer sourcing outputs and sinking inputs

IF, big if, I read some other posts correctly, a sinking input on the board would need to be fed a sourcing output "on the other end". Is this correct?
So, thinking ahead to perhaps buying some new limit switches, they would need to be PNP for sinking inputs on the board...?

On that same note, if the board outputs are sourcing, the inputs on the servo drive would need to be wired in the sinking way?

Yes and yes, probably, it is 8:20AM here and i have not slept yet, so i might be hallucinating.
As for switches, i never worry about them, usually a single resistor is enough to make them work, whatever the type and input.
