Sorry to hear of the board bricking.

I thought the whole thing of the RIO project was to get away from any softcores or it may seem now hardware cores. Or is my lack of FPGA experience showing through once again

Not a lot of info to go on.
If your PC uses a realtek NIC I would search the forums for what to do. That would be a good starting point.

Next thing would be to ensure no "noisy" wires are crossing signal wires.

Next thing would be to ensure that the PSU that are powering the Mesa baord are giving a clean voltage. A good quality PSU, such as Meanwell or Weidmuller are good choices. Ensure the servo drivers are wired according to the manuals, don't skip the recommendations fro any filtering, not a cheap exercise, but well worth worth it.

Keep power wiring away from signal wiring. Don't expect a "rat's nest" to operate trouble free.

Don't wire every at once, wire one section at a time and test, trouble shoot and fix as you go. If something stops performing as it should it makes trouble shooting easier as you can start at the last addition you made.

Where ever possible terminate the ends of bare wires with "bootlace ferrules" makes inserting wiring into screw connectors easier and prevents start strands of wires floating in the breeze.

If you have implemented all these measures and have "noise" issues you will need to provide far more information. PCW may chime in and ask for you to do some "ping tests" and such, as this is his domain I shall leave it to him to guide you through that part.

if i'm already putting so much time into the zynq parts, then it should be worth it

I've also ordered an Antminer s9 board, which has more IOs

If I remember right, linuxcnc doesn't do synchronized motion on rotary axis.
Maybe wrong term but feeds,speeds and acceleration is determined by x,y,z only and the rotary axis will do the best it can. When it can't keep up this in the figure happens.
One usually uses the inverse time feed specification G93, and calculate the time needed for the movement in the CAM post-processor.
There are converters on "the web" that can translate G code to G93.

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?





 

And you can build a Linux system entirely from source, if you are into that kind of shenanigans.
Boot from a tftp server and run the OS entirely from ram. Or boot from a tftp server and mount the rootfs from a third machine.
A lot of home routers/access points/modems run Linux.

Running a Linux desktop is quite boring and mundane when one realises what Linux is capable of, and what a user can do with it once they read & experiment.

That's correct. I'm going to try to adjust the gain settings and see if I can get this tighter. Any suggestions what settings to look for? Many thanks

As had been suggested before, it looks like the drives themselves need tuning.

Not a firmware issue.

I would not expect motion until you enable the drives.

If there is an analog output issue, it typically shows up as a non-zero
output voltage when the 7I77 is powered.
