I forgot to factor in Limit Switches in my planning of my build. I have a dual y axis cnc with the panucat gradus m1 pro. the controllers only has 1 input for each access for limit switchs. problem is i need 8 total 2 for x, 2 for z and 4 for y i was wondering can you chain the limit switchs so that they go into one input on the controller? from what i understand there are two types of limit switchs always on or always off which one of these types is the limit switch that is sold in the openbuilds store and also does anyone know what type the gradus is designed to work with?
