Controller build for Plasma

If you prefer WIFI, external USB-WIFI adapters are usually OK
The built-in minPCIE cards are the usual culprit with latency issues.

Thanks. I do have one I can try.

First off very nice and clean controller build, just hope mine comes out half as good. Quick question why dual mesa cards? I was under the impression one 7i96 can be flashed to support multiple THCAD's?

Thank you. I am only running one 7i96 card and two THCAD-5s.

Oh ok i get it now, i was under the impression the 7i96 did it all, but you need separate daughter cards for each THCAD used and the 7i96 is flashed to control multiple cards. Glad i found this out before ordering lol

The THC cards are not really daughter cards ass they are stand alone cards. They do not plug into the 7i96

But if you need two THC then the 7i96 has to be setup up to have another encoder on one of its inputs

Mesa provide a bit file for download that does this.

Well I didn't end up putting the controller into service and now I get to read through my thread again to remember everything I have done. I ended up blowing away the tiny pc that I had linuxCNC setup on so now I need to start that all over again.  Does the latest ISO from the website support the mesa 7i96 or do I still need to do something special with the kernel selection?  I realize the 7i96 was replaced with 7196s because of availability issue for the FPGA. Hopefully should be able to follow the same process to get it setup again.

Thanks. Just reinstalled and updated.

I've installed Debian Bookworm using Rod's instruction document and I am trying the 6.3.0 kernel he posted in the document.  So far for the last few hours running the script to test latency looks like below.  I'll let it run overnight to see if it gets worse.  If it stays as below is this ok?
