Wiring of oil pump.

And another thing...

Label your wires, both on the drawing and the wires themselves.  If you're going to be doing this DIY CNC thing you want to get a label printer, preferably one that prints directly on shrink tube.

Labeling Nirvana

That one's swank, but they have cheaper ones that you can program with your phone or PC.  Epson has the least expensive tape/shrink tube, and they also have the smallest diameter tube available.

How nice is this for troubleshooting?

 

 

Thanks again spumco. Now everything is crystal clear.

I took your advice and ordered the phoenix relay.

I will keep the Ethernet cable in mind but have pretty much everything wired up now.

I bought a label printer as well but did not go for the shrink tube option (which looks very slick btw). I went the cheap route and now my enclosure looks like an advanced minesweeper field, i.e. flags everywhere.

I am intrigued to see your entire enclosure - looks all very tidy. How far along are you with your build?

Cheers

I hope you don't regret that.  I've found that sticker-flags move and get in the way of everything if the least amount of coolant or oil gets in the enclosure.  If you think you might do another enclosure treat yourself to decent tools and a shrink tube printer.

My current (personal) build is 99% finished, electrically.  I've repurposed my 4th axis as an ATC motor, so I'll have to fit another drive somewhere when I reinstall my 4th axis.  Maybe in a separate enclosure as it'll be an AC servo that doesn't need a AC-DC power supply.

Other builds  - 4 plasmas, 2 commercial automation devices, powerder-coat ovens... are all finished.

I'm not a professional, BTW.  Self-taught, but a bit OCD and find I enjoy wiring.

Photos 1 & 2 are of my mill control panel.  There's an SBC and a 7i84 for an interface.  I can't seem to find a pic of the main enclosure ATM.

Photos 3,4,5 are of a 6'x12' plasma I built.

Photos 6, 7 are of a sister plasma.  That one is 5x10, but has provisions for a 4th axis and also a VFD to run an interchangable router spindle.  Hence the need for two enclosures.

Found a couple of my main enclosure.  Keep in mind that these were taken some time ago and there's been changes:

• Switched Copley servo drive to a GS-3 VFD
• Relocated stepper drives so they're mounted 'normally' on the backplane
• Finished wiring & labeling everything

Note - the little box things on the outside of the enclosure are my home-brew version of quick-disconnect field wiring ports.  Rather than drilling a million holes through the enclosure, I cut a big hole and stuck a shallow die-cast aluminum box on the side.  A panel would have meant all the wires would need to be tidy inside the main enclosure.

Instead, the box houses the nest of I/O wires and a bunch of GX-12 and GX-16 connectors let me wire everything up inside and then make field connections later.  A single 24V+ and 0V wire go from the Mesa field wiring to the sub-box and all that's coming out are the signal wires back to the 7i76ED.

The upper sub-box is 24VDC I/O, and the lower one is 240VAC to coolant pump, lights, spindle motor fan, etc.

Spindle/encoder cables and stepper power/encoder cables are all run though a panel between the two sub-boxes (not in the photo).  Didn't want any noisy intermediate connectors in those cables... 

Tang had to leave in a hurry !
