That's a good tried and tested combination...it's what I have, lovely kit.

Just to terminate the shielding on the cy cable where I have to cut it back... maybe an overkill but only costs a couple of quid!

These little beauties just arrived :)

Hello!

Time for an update.

So I've done a bit more work on the z axis and you can see progress on this here: https://youtu.be/mWTSq0ZqsLE

But my main focus has been on getting the electrical side started.
Many thanks to Dean and Clive who have both been super helpful and now I think I have a workable circuit diagram which I feel happy to share on here. A word of caution to anyone just getting started, please do not follow this verbatim, there are no-doubt some mistakes / things I will change as I go and as with drawing out the mechanical stuff before you start, you need to do this yourself to get your head around what you are doing. That said, I'm more than happy to receive comments from experienced members, particularly if you spot any dumb mistakes.

I now have, or have on order, all the electrical bits and bobs, cable, ferules etc. apart from the big ticket stuff -the drives and controller which I am leaving as late as possible. I also need to figure out what current rating I will need for the 24V supply.

Really excited to start this part of the build finally!

Cheers everyone.

Looking good Joe
I removed my 12v supply and simplified everything to run off the 24V supply. Just need to pair up 12V devices in groups of 2 in series . E.g. 2 fans or fan and motor
Less things to go wrong and less space required in the box

Also I'd add a switch to the water cooled spindle pump - looks like it will run all the time which will be annoying plus may heat the water a little

I have a 12v supply on order but it was only cheap. Clive has also suggested running all from 24v. I already have two 12v fans but could get one more and run in series with the 12v pump I guess. I was going to use a mcb instead of a fuse for the pump so I can switch it off with that?
