Problems with Lichuan Ethercat servo drive

Category: EtherCAT

I changed all the gains to see if one would have an effect on the offset error. Nothing. I've put a light integration loop in the cia402.conf file. That solves the problem. I don't like it. I would appreciate hearing from anyone running these amps. If you have this issue or not. Thanks.

I made:
sudo apt install linuxcnc



This installs LinuxCNC 2.9.4 and change_g43.ngc was added only in master.

I doubt it, if any read data is corrupted, all data is suspect.

Can you run this command when LinuxCNC and modbus is running:

sudo tcpdump -c 100 -xx -i eno1 > dump.txt

( substitute your Ethernet device name for eno1 )

and post dump.txt here?

With this config
I have crazy data to encoder.00.input-a and encoder.00.input-b like the first video
encoder.00.position and encoder.00.velocity seems unaffected it will work if noise is
only to encoder.00.input-a and encoder.00.input-b ?
