Differential encoder hard crashes the PC MESA7i77

Category: Driver Boards

Do you have any normal encoder, or a servo motor with encoder attached to it?
If yes, wire it and test, see if the same thing happens.
Do you have the spec for the MPG?

Differential encoder hard crashes the PC MESA7i77

Category: Driver Boards

I had a few more minutes to work on it this week - I wired the encoder via a short pigtail to the 7i77, got the same results as before. So the issue cannot be a faulty wiring connection.
I also found that my 5vdc power supply may not have been grounded, so I fixed that, no change, the PC still crashes.
I also tried all the other encoder locations on the 7i77, all producing the same issue.

I will keep updating as I do more.

Nice work, excited to test it out!

I am reminded of Excessive Overkill's youtube channel (around 18:39):

Yes, this does not seem to be a latency issue but a connection issue.
Not really sure what the cause is. I have a 800 G1 here running
LinuxCNC without any Ethernet connection issues so I don't know.

Is is possible to try another PC to try and isolate the issue?

Rod, no amount of tuning is gona help on a disconnected link.
-
Did you change the cable?
Do you have a USB-to-LAN adapter to test with?
Do you have another PC to test with, any PC with a different cable.
-
ip -s link show eno1
But, only after the Mesa is connected and trying to run LinuxCNC.

There are a lot more tuning settings required but lets get the main one
Can you type: echo $(nproc)
and then back in grub customizer add isolcpus=X where X = $(nproc)-1 from what is printed from the line above.
Then reboot.

OK a 8300 USDT uses Intel hardware and should be fine

Is AMT disabled in the BIOS?
