I hate the 7i97T

That's great!


It does need:

setp   hm2_7i97.0.pwmgen.00.offset-mode 1

and not required but an added feature would be:

setp   hm2_7i97.0.pwmgen.00.dither 1


for all 7I97/7I97T PWMgens


Also a better default PWM frequency would be 48 KHz



 

Done!
Thanks.

I mean i love the Mesa cards and Linuxcnc, but this card really made me reconsider using Mesa and Linuxcnc. The point where i broke was, after getting it to be recognized by mesaflash and mesact Linuxcnc would tell me network unreachable. This problem followed me through the whole process, either "network unreachable" or "no such device at 192.168.1.121"

EDIT: So far i got it running, but the whole process to get there is tiresome.

You need to configure the network on the host for the Mesa card.

Also 192.168.1.121 is not suggested for LinuxCNC use as it's  in
a commonly used NAT range.

Suggested setup is to use the 10.10.10.10 address on the Mesa card
(via the IP address setup jumpers) and set  a static host address of
say 10.10.10.100/24.

At this point you should be able to ping the Mesa card:

ping 10.10.10.10

 

the whole connection thing was already working on mesaflash and mesact, i could confirm with mesact, every test was a success. But Linuxcnc would fail, In the end I had to click on the network button top right and then it worked.

As for now i´m okay. Sorry for the rant, but I was used to it being easy setup with Pncconfigwizardo

I found the problem I had the whole time but Linux didn´t point it out enough for me. Since the 7i97t is connected via ethernet i ran into more and more problems when I approached wiring up the machine and testing in and outputs. Today i started wiring the Lathe to the Mesacard and i didn´t get any MPG Handwheel feedback at all, a few seconds into starting Linuxcnc I´d run into queueing errors.
Little research pointed me to major network problems, causing the 7i97t to indicate a fault with CR7 red whenever i try to connect and hold connection.

I turned the checkbox "show notifications" in the network tab top right on and viola i got an error "disconnected". So i went with your suggestion and set the Jumpe on the card to eeprom default ip=10.10.10.10
still the same problem. For sure i changed my own IP to 10.10.10.100. Still the same. I changed the cable. Still the same. I tried a lot of thernet configurations.

In the end, the fix was: The subnet mask was set to "24" and not to "255.255.255.0". After fixing that the card connected right away and the network symbol stopped spinning. Since I´m not familiar with Linux, that spinning symbol gave me bad feelings but there is no Tooltip showing up, telling me what that icon actually means.

Now got already both MPG wheels hooked up. Somehow I cna´t find the TB5 IN8 pin in Halshow...
