New start

I use to take the 5volts from my pc's USB port for my previous cnc and it still works fine this way, at the hands of his new owner.

Will have my pc in my controlbox.
Is it safe/okey/good practice to use 5v from pc psu or should I use the nice chinese psu that I have bought?

You don,t say what you want to use the 5V for!! or what psu you have bought. looking at the BOB that will need 5V and 12-24V to run the 5V could be got from the usb. Personally I would have a separate 5V PS.

Haha you my friend are correct :)

The only thing I got planned for 5v is the Bob and it's signals to the stepper drivers ( pul dir ena )
I've bought a 5V 2A psu and still thinking about using it. If I were to use the pc psu I don't think I would connect usb but get 5v from a Molex harness. That way it's straight from the psu and not through the motherboard. If that makes sense??

Good to know :)

It seems like a easy option.
I don't know why it's recommended to not use usb to power bobs.. If it's unreliable volt levels or if it's a grounding problem with loops or something?

Leaning towards this aproach because pc psus are supposed to be stable!
