Control box wiring: cables, terminals, connectors etc.

Ok I don't see anywhere in the BOB manual that you connect all the pul, dir and step to the enable pin. So not sure where you are reading this.

Oh wait, that's right, sorry, I mean that all STEP+, DIR+, PUL+ are going to pin 5V+, which makes a total of 1 pin on BOB going to 12 terminals (3 on each driver). Excuse my mistake :) There are still 4 wires (on for each driver) going to 1 screw terminal, I don't think that can fit easily, looking at the size of the screw terminals.

You link all the +ve on the driver as you only need one wire to carry the +ve to the driver as it shows on the BOB manual page 3 Hope this helps

I see what you mean :) It does help ! I need wire splicers to split the 1 to 3 cable once close enough to the driver then, is that correct ?

No just connect the +ve to the first terminal then with a short link connect that terminal to the second and then the same for the third.

No power reduction will happen ? Weird, seems like a parallel connection to me, but that's where I am a total beginner :) Thanks for the advice !

It is a parallel connection as it would be if you connected all the cables to one terminal. As regards power reduction the driver signals are only in mA say about 10 so you can use very small dia wires Cat 5 is ideal
