How Would You Upgrade An Old Ox CNC Build Into A Serious Machine?

[JAZZCNC]

And Jazz... your setup would set off my OCD for sure. I don’t mind rats nests behind the TV and such (because I alter it so often) but for a machine that is moving around so much I made sure to keep my runs as clean as possible. Hell, I was even planning adding dual drag chains to my new machine so that I can keep the water line separate from the other already full drag chain. But maybe my chain is too small. Dunno, not checked yet.

Don't get me wrong I'm not advocating running a rats nest, far from it, and all the machines I build are wired and routed correctly neat and tidy. I am quite Anal about to be honest and drive my helper mad if things are not routed or wired just how I like them.
But My own personal machine is a testbed so I'm always pulling it apart and/or wiring something or other into it so how it looks is of no concern, thou it is safe. It's also why you'll never see a photograph of it.

However back to the cooling, like Neale says don't overthink this one as it doesn't need any fancy cooling system. Every machine I build uses a WC spindle and all of them bar 5 or 6 have had 20Ltr tubs of water located either under the machine or on the floor using a 24Vdc pump with head height of 7-8mtr.

If you are doing long jobs 2hr's + then it's a good idea to had a flow sensor just in case the pump goes down. But other than that KISS works.

Edit: If using bucket setup just add some antifreeze and try to use a bucket that blocks out light and you'll have no issues with water going bad.

Here's a setup that didn't use a bucket but instead used a small tank with pump inside bolted onto the rear of the machine. This also works perfectly and the tank only holds 3ltrs of water. Before the pump failed on my machine I was testing a PC rad with fan and one of those cheap nasty small pumps with 500ml reservoir integrated into it. This worked perfectly until the pump failed which was more to do with it being a cheap nasty pump.
