So last night I wired my machine back up following my notes on how it was before I took it apart…and apparently I messed up my notes because after re-wiring all I get now is steppers juddering so something is miswired. So much for my notes, must have got something mixed up and am going to have to figure it all out manually again.
So figure I may as well give serial a go.
But I want to confirm as it’s not entirely clear from your initial post…did you switch to 16th stepping when you switched to serial? It sounds like you did but I’m not entirely sure even after re-reading that post a few times 😀
