Is a parport fast enough?

Fwiw, I'd just toss away that useless isolation and power your kit from the same 'clean' supply your control board is getting. You'll have to clean that up anyway, might as well use the same rail for the scales/probe/setter/switches/all.

Less is more!!

Are you talking about me just using buck converters instead of isolation? Just use my 24V to power everything....? Isnt there a bigger risk for noise and ground loops? I think i would still need to isolate some things... ie. plasma torch. All that said.. I do think i could skip isolation on the servo amps.. As you can see in the photo... I was just 'following protocol' as they say!   

 

Noise is a 1970 thing. Everything's high/low pass filtered with built-in data integrity nowadays; modern drives, servos, sensors, it's endless. Only noise we hear lately is politics, misinformation, chatgpt, shit like that

But yeah I hear ya. Kw coils and torch ain't docile environments...

Plasma makes a lot of noise...
And so do servo drives, but not nearly as much as plasma cutters.

Yes, they do! As do VFD's.
