hm2/hm2_7i92.0: Error finishing read! was created by angelnu
Usually it is Joint 2, sometimes joint 1 or joint 0. I have to shut down the 7i72 card and restart linuxcnc.
The error is running a program, but sometimes I have gotten the error Error finishing read on 7i92 with no movement of the motors. What could this be due to?
I have a Mesa 7i72 board with a 7i76 connected to an orange PI5, The network cable is Cat6, the motors are Chinese servomotors connected as a direction step, I have executed several times the command:
sudo chrt 99 ping -i .001 -q 192.168.1.1 -c 50000
To see if packets are lost and the result is always 0% packets lost.
I have lowered the maximum speed of the engines in the ini file, I don't know what can happen. Any idea?

Change the default IP address with:

Pinging 10.10.10.100 means you are pinging your PC, not the 7I92
What you need is:
sudo chrt 99 ping -i .001 -q 10.10.10.10 -c 50000
What host hardware do you have?

That's more that 1 ms so a reason for timeouts
You might try a 2 ms servo thread
(2000000 ns in the ini file)SERVO_PERIOD = 2000000
