Controller hardware suggestions for first DIY build

Sorry when I said Logic power, I should have said field power. Yes just connect the power supply to the BUS board and then patch across to the field power inputs. I used massive bus bars I could get locally as I had no idea those little Mesa parts existed. Its now super simple to wire in various relays and inputs via the bus bars

Ok, so go from the 24v PS to the Mesa BUS bars, then from their to field power?

If that is correct, how then would I then connect an PNP-NO proximity sensor? I looked at Norbert's schematic for the PNP, but it only shows connections based on NC.

So a prox sensor needs +24v and -24v so put them to the bus bar and then the output goes to an input. It does not matter if its NC or NO.

I mounted all my sensors on the moving gantry so I bought a couple of DB9 break out board thingies in the control box and used 9 core shielded cable to run common +24V and -24V up to the gantry ends and to the Z axis assembly and ran the inputs back on the other wires. On the Z axis, I made my own breakout board
See my spaceship:

And revised later

And becasue I bought NPN sensors, I added pull up resistors on that board.

I cheated on the gantry ends and just used a terminal strip on both sides. You can see a cable going thru the gantry rail to the other side to another similar setup

The spaceship is awesome! Also, FWIW, I enjoy telling my coworkers that I chatted with 'the Australian' and he explained it like this... me doing my best Australian accent

Would you mind sanity checking this for me? The blue and brown are the 24+ and 24- ... does it matter which is which? The black is the output wire that connects to the input on the Mesa card, right?

I am going to take the field wiring from the Mesa 7i76e and connect it to the Mesa din mounted 'common' bus bars. Then I will connect those bus bars to the 24v PSU. AND THEN I will connect these blue and brown wires to the 'common' bus bars, sound good?

I also do that a lot, for plenty of Australians and from other countries, but i can not do accents, except say : iminem!

hahaha ... glad I am not the only one!

Where abouts are you located?
