What software did you use for your wiring diagrams? Looks very good and easy to follow.

Visio but any 2D CAD will do, it's just that I had already created the symbols with it. By the way a good source for electrical symbols is the Telemecanique catalogue, you have to draw them youself and save as a block but it's still a great resource.

Do you plan to have any control for things like Air/Water/Vacuum in the panel or maybe just have them switchable on the machine? I plan to have them all individually controllable (ON-OFF-ON with spindle).

No not particularly but I have included some spare terminals if need be with the idea of adding another breakout board, the Smooth Stepper has connectors for 3 ports. The enclosure is pretty full now and I like everything to fit onto the backplate, other than door mounted buttons etc.

I like the idea for the spindle motor over temp. Have decided how you will implement this at the spindle?

The spindle is an ELTE 2.2kw TMPE3 12/2 and has a built in switch for temperature.

Also I spotted your link to the “System Design for Control of Electrical Noise” pdf in another post. Just been reading it, great info, particularly the parts dealing with “clean/dirty/very dirty” cable runs. Very interesting.

In my panel all the low level signal wires go in the right hand vertical trunking while the stepper motor and power wiring are in the left hand vertical trunking. The stepper motor wiring and spindle motor wiring are in screened CY cable, all screens earthed at the terminal rail and nowhere else.
If anyone is concerned, it might be worth their while to look up IP2X for electrical panels, one way is to put a full perspex sheet over the whole guts secured by screws at the corners.
