hi boys, my printer has stopped working properly cause the z axis doesnt move when homing, but if i move with grbl it seems to work fine. if i use my old raspi3 i get suppresing duplicate logs message when start printing and printer doesnt work. with other raspi3 (newer) i get "undefined feed rate" error (remember it works properly with grbl). Wtf with my dammit configuration???
