Fried my LinuxCNC Setup

Well, that never took off. Purchased a used PC with a parallel port breakout board and set everything up with what looked correct. Used a buck converter to power the board and noticed it wouldn’t change the voltage. Powercycled the steppers and breakout board and PC immediately turned off. Left the PC unplugged and the buck converter came to life at 26 volts, immediately blowing the caps in dramatic fashion. Well now with a fried PC and breakout board, I’d like just a ready made solution to power my lathe. I was going for Linuxcnc as I wanted spindle sync and backlash compensation, so if there are any great budget options that are just a ready made solution so I can stop worrying about wiring and flashing boards, that would be fantastic.

The only option would be to buy a cnc lathe, which is not a budget option.

Every other option is going to require you to do some wiring.

Even something such as this, github.com/clough42/electronic-leadscrew, will require you to do some wiring. And this is only a solution to screw cutting and doesn't have any cnc capabilities, tho it doesn't connect to a computer.

Once a again another Electronic Lead Screw, www.rocketronics.de/en/els/ no connection to a PC,no cnc capabilities but does other some extra features. Is still a user install, so there is wiring involved, but no connection to a PC. not really a budget solution.

First mistake was using a buck conveter, 2nd I would seem to be not checking the operation of the buck converter prior to connecting everything up. 3rd mistake would have been to triple checking everything.

Simple solution would have been to power the breakout board from a known and working 5v supply or whatever voltage the BoB required.

I would think the simplest option would be a used PC with a parallel port
and one of those "Mach 5 Axis" parallel port breakouts. 

For a small amount of 5V, a safe option is to just use PC USB power
(which is what the "Mach 5 Axis" BOB does)
