Wiring ATC with UC300eth 5LPT and UCBB

[Phil Mayor]

Hello,

When I originally decided on this build I wanted to use as much of my old build as possible, but further, down the build process I get, I realised I didn't know what I was doing... One of the items I wanted to re-use was my AXBB-E, however, I realised it just doesn't have enough Input ports to use an ATC Spindle with, so I've now got myself the UC300eth 5LPT, with UCBB (breakout Board) using UCCNC. I have it working i.e. it powers on and I have movement on all Axis, but I really want to utilise the ATC Functions - but only have fundamental knowledge of the electrics.

My goal is to have a "Follower ATC" connected under the moving Gantry with a Pneumatic Valve that pushes the Tool holder out during the Tool Change and retracts back after it's done. I have seen this on Blue Elephant Machines and Mercury CNC Machines also have this style Tool Changer. I realise I would need a custom Macro (which I am looking at) and solenoid Valves to achieve this.

At the moment I just want to be able to wire the Spindle up for ATC and also the manual push-button tool eject and I will look at the "Follower ATC" at a future date

If anyone could give me a hand it would be appreciated.

My Spindle model
GDZ143X133-9L

I have the Spindle power hooked up U, V, W but nothing else....




This is my interpretation of the wiring (but I'm too scared to try it out in case I fry the bob) I'm not 100% confident where the wires go to be honest, I'm not sure if the should all go to the bob or some to the VFD?
