Wiring the Hypertherm interface cable

My opinion on the matter is this. I have full faith in Tommy so I don’t believe his advice was bad or ill intended. It was more so practical in the sense that it’s not a real problem he has faced. I recognize the desire to put air on the side of caution as Rodw is suggesting.

personally I feel like it’s such a cheap addition but adds a sense of security. Therefore I will most likely include it.


with that being said, please look at my entirely comprehensive wiring instruction book. Is there anything I’m missing or I have wrong? Please take a look and let me know
 

From a quick glance, it looks good, with plenty of info.
Maybe change the sensor wire colors as those are mostly blue -/brown +/black out.
And if you want to make it public, change the + and - rail colors, usually the red is + and the black is -.
Good job of putting everything together, thank you.

Great! Thank you so much. It’s taken me a long time to make this and I’m proud of it. I hopefully won’t have to ask any more basic silly questions. I wanted to make it as explanative as possible. Okay, I will make sure the colors are switched. Doesn’t black go to + and red to - when working with higher voltage Such as an extension cord?

if you get a chance please take a deep look at it all to make sure I’m not wiring anything wrong, as you know a single missed wire can cause much heartache. I would really appreciate that. Again thank you

Went through it again, it looks good.
Still, i would change the + and - colors to red and black, it still messes with my head when i read this !

Okay I will do that thank you very much! Finally happy to have a full wiring instruction “booklet”

if there’s anything I should add, or anywhere that would benefit from some extra protection or anything else let me know and I’ll add it or change it

Adding automatic fuses to the AC side of the power supplies is a good idea, 1 for all supplies or 1 for each, does not matter much.

Edit:
It just occurred to me, did you see this:
forum.linuxcnc.org/media/kunena/attachme...8/7i76_Anschluss.pdf
forum.linuxcnc.org/27-driver-boards/39332-thcad-10-7i76-wiring

I have seen them, it’s just that I’m not using all the things one of those used and I’ve seen other things out there, obviously wrong, but contradicting those diagrams. I wanted to be sure that I had everything right for my specific machine. Thank you so much for your help Tommy.

okay, I’ll do more research on automatic fuses so I know how to implement it, where, and what kind. Then I’ll add it to the diagram. Again thank you!

Hummm, I see ferrules  (Wire FE) but no crimping tool? Maybe you need something like this: www.amazon.com/IWISS-Self-Adjusting-AWG2...rrule/dp/B00ODSJGSW/

You really don't need a 1000w power supplies for the stepper motors and drives you are using. I can assure you that a single 300W power supply would be enough for all three axis. But to be on the very safe side I would go with this 600W PSU: www.amazon.com/dp/B079D7H2L1/

Likewise the 5v 10A PSU you selected is again WAY too much for your setup, but hummm, not much savings if you go with a 5A psu ...

Ok, one more things...

On page 16 you wrote "there are 4 drivers"... Why 4???   (X,Y,Z + ?)

EDIT: I guess it is XYYZ  (Gantry with 2 motors)
