If you get a read error but no red LED its means there is a 5v power issue
I have seen this fairly often with marginal power supplies.
(the 7I96S card gets reset by a power dip) If host communications
are lost (and there is no power issue) the red LED will illuminate,
indicating a 7I96S watchdog bite.

A higher servo thread period does not affect speed but does affect
maximum acceleration as there are fewer velocity steps in the acceleration
ramp. This will chiefly affect high acceleration machines

Just tried again and there is a red led when I get the error. The led is named "INIT" on the board.

I just tried with period thread at 2 ms and I have not encounter the issue.

What does it mean ? I have too much latency ?

Just tried to install these driver as my NIC is one of them but I have got an error :

Same here --- After receiving my new mesa 7i96s on Monday, I experienced similar problems with the
Realtek driver in latest Bookworm kernel 6.1.xx . After reading some of the posts on this forum, I
elected to install a new kernel, as an option to possibly resolve the Realtek issues.

I managed to add the debian-backports repository to sources.list... which made it very easy to install the new 6.5 kernel. After installing the new kernel, an attempt was made to switch the r8169 > r8168-dkms... but no joy.
I got the same errors as recently posted. Otherwise the new kernel+drivers, along with boosting the servo timing to 2000000 allowed me to operate several sample projects without issue.

I am not now convinced that new kernel has 'fixed' the problem, as another "finishing read error" popped up when loading gmoccapy in main program. Since have the option of replacing the pci-x card, I've simply decided to switch the card to Intel...my time is worth more than $25 :-)

PS: Thanks to all the folks that posted suggested remedies for the "error finished reading" and the related "joint following errors", they really came in handy!

Did you guys install the linuxc-headers? DKMS drivers are compiled during installation and therefore the kernel header files are required
Install them with:

sudo apt install linux-headers-$(uname -r)

Hi ! When tried to install headers via apt , I got notified by apt of the conflicts, as suggested/told to "apt --fixbroken"... which I did, and then apt proceeded to remove the r8168-dkms.deb package previously installed with dpkg utility ;-)

... No surprise! Should also report that I am running Deb 12.2 Bookworm with backported kernel 6.5 from debian.org source.lst. Note: All unnecessary systemd processes like avahi, NetworkMangler, mdns...have been terminated ror disabled.

I'm fairly experienced (retired) with networking and linux debugging, and have some time to test out conditions my hardware will support. Happy to help out if I can, just let me know. --Gary

Yes, headers for my kernel (6.5) are installed.

I don't have much experience with Linux so I can't really do anything on my own about this error
