Question about Prox Sensor Wiring on DIY Acorn Controller

Build Logs
1

Hello all. I recently received my custom order of the PRO4824. What’s different? I had my own closed loop stepper motors I wanted to use that ended up not being compatible with the EX Controller, so I instead ended up getting Core Centroid Acorn separately.

I’m currently in the wiring stage of everything and I’ve kinda hit a small roadblock.

The custom kit I purchased came with all the proximity sensors, but now I’m a little unsure how I should wire everything up to the Acorn.

Typically the Acorn has one of two ways to wire up Homing/Limit switches. Either “Home All” or you can wire them all separately on a per input basis on the Acorn. Input 1 would be for the X Home sensor, Input 2 for the Y sensor, Input 3 for Z. But since there’s a total of 5 sensors (1 for X, 3!?! for Y and 1 for Z) that came with the kit, what is the best way to wire these up and what settings to use in the Acorn Wizard while keeping the homing and squaring functions in mind?

Just for other info to keep in mind, I also have a tool touch-off sensor for ATC tool length offsetting, and the Avid touch plate for material zeroing setting.

Any help would be appreciated.

Thanks in advance.

I think I can help you here… but help me understand what you’ve got:

Sounds like you have our machine frame, and an Acorn controller that you’re planning on building into your own custom control box? Is that correct?

Or do you have our pre-built control box?

Correct. Avid Machine Frame while building Custom Acorn Control Box.

Ok, in that case you might be better served by asking over here: https://centroidcncforum.com/

This is Centroid’s forum where all of the custom machine builders hang out. You can get lots of good answers to your questions and some example builds there.

And if you want some schematics you can look at: Centroid DIY CNC Hookup - Schematics

We publish full schematics for our control which you can look at on our support site if you want to try and recreate anything we have:
