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.

Hello everyone, 
I am using mesa board 7I76E to control 5 axis cnc with servo motors 
I installed the linuxcnc on a laptop when i run linuxcnc with the mesa board on the laptop everything works well i got some wired interference like loosing Ethernet communication with the board or the mouse pad will be crashed all the time but i was ignore them because they didn't really influence on my project.
After that i installed the same version of linuxcnc on a desktop computer in fact i used the same ssd so it was the same software, the same configuration at this moment the noise issue became more than usually now i lost the communication every 5 min around ana that's a big problem. Do you have an idea what is the exact issues happened to me , how could i decrease those noise 
Thanks in advance 

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.

made it,
i bricked the board

because the linux version on it was too old i wanted to update, but that went wrong somehow, now i'm trying to compile a new one and get it running again somehow.

it's no fun and very time consuming

And used it's desktop versions for over 2 years, probably 20 years back.

Probably need the drive manual for that...

If it's like a classic motor drive, there will be three nested PID loops:

1. Torque (current) command/feedback --> torque (current) out
2. Velocity command/feedback --> torque out  
3. Position command/feedback --> velocity out

Is there any tuning program available for the drive?
