Control box wiring: cables, terminals, connectors etc.

Here is the BOB manual. It seems to me that there is only one enable pin. Otherwise you have to use the 4 pin serial connectors, which I have no idea where to get the matching males..



Also, I have done a search on the forum, but the search engine is not so good. I haven't found a thread that explained that type of information :/ You know the forum better than I do ^^ I have had this search problem since I started using the forum. I mean, honestly, even using the advanced search with "control box" returns 20 pages of threads among which the first 3 pages haven't given me any clue...

I have a schematic diagram on its way, not ready yet. But wiring is not really my issue so far, as I understand quite clearly the big picture and have ready the AM882 manual, BOB manual, and the thread talking about the 2.2kw chinese spindles (so I got most of the info needed on that side). Once it's ready I will post it on here to get it checked by you guys.

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 !
