Installing Mesact was created by Z3rni3

Hey.
I've been trying to get a 7i95T to work but cant seem to get a working config.
After reading on the forums, that the Mesact helps out a lot i wanted to give it a try but it seems, that i'm doing something wrong installing it.
I'm guessing that i am missing the public key

This is the error it gives me:

cnc@raspberrypi:~$ sudo apt update Hit:1 http://deb.debian.org/debian bookworm InRelease Hit:2 http://deb.debian.org/debian bookworm-updates InRelease Hit:3 http://download.opensuse.org/repositories/science:/EtherLab/Debian_12 ./ InRelease Hit:4 http://deb.debian.org/debian bookworm-proposed-updates InRelease Hit:5 http://deb.debian.org/debian-security bookworm-security InRelease Hit:6 http://deb.debian.org/debian bookworm-backports InRelease Hit:7 https://packages.microsoft.com/repos/vscode stable InRelease Hit:8 https://www.linuxcnc.org bookworm InRelease Get:9 https://gnipsel.com/mesact/apt-repo stable InRelease [2,608 B] Err:9 https://gnipsel.com/mesact/apt-repo stable InRelease The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 6F8DFB65A82CD322 Reading package lists...

How to build a CNC Router?

Category: Milling Machines

Did a bit of testing with the PC i have lying around (mostly Thinkpads). The old Panasonic thoughbook seems to have died.
My TP x220 (nearly all peripheral deactivated in the BIOS) does the latency test with just not exceeding 35000.
What I still not understand is the complete chain of devices from PC to the machine. As I understand it:
The budget way: 3 TB6600 connected directly over parallel port to the PC (limits the router to what the PC can process (limiting point is the latency)
The more expensive , but higher performance way:
a mesa ethernet card (FPGA doing most of the latency related stuff) connected to (more expensive and powerfull) stepper drivers.

What I seem to miss is the point of the daughter/ I/O boards (like 7i78, 7i76). Are those additional boards to have more options like (spindel speed/ on/off, peripherals like dust collector, air assist etc) or to those have the stepper drivers included).
Please let me know, if those info is somewhere in docs and I managed to miss that.

Yesterday I changed it to a NVIDIA Quadro NVS 450 I had on hand ... and now it's seems to be fine : I loaded all my files again and again with no problem.

I don't remeber what was the old CG but I will have a look next time I'll go my wookshop.
