I hope this is the right thread, please move if it isn't...

I'm investigating converting my NUC to a Pi 5 - the install from the official Pi5 image went perfectly but as I'm using a Mesa 7i96 and the Pi will end up inside the cabinet, I need to use a USB WiFi adapter for its external antenna.

The dongle is a Reaktek RTL8811AU (external antenna'd ones seem to be getting rare) so I think I need to install this: github.com/lwfinger/rtw88?tab=readme-ov-file#installation-guide Happy to be corrected if I don't because I'd rather not.

If I do aI get 6.12.11 but this:is "Unable to locate package linux-headers-6.12.11"

An apt search reveals a bunch of 6.1.0x Linux headers and a few 6.12.12+bpo headers but no 6.12.11. Not sure what to do now, so any guidance would be appreciated - even if it's a link to a natively supported USB WiFi!

Edit: Runninginstead of apt searching for 'linux-headers-6' reveals 'linux-headers-bcm2712-rpi/now 6.12.11-1 arm64' are already installed. Why the headers don't match the uname -a is slightly above my pay grade.

Hello,
I am installing ethercat but the communication light with the drivers is not flashing and it is not communicating with the drivers.
raspberry pi 5 
rpi-5-debian-bookworm-6.12.11-arm64-ext4-2025-01-27-0140.img.xz - linuxcnc 3.5.9
I used to use linuxcnc 2.9.3 and there was no problem.


 

Heh. I would have to say probably "yes", to both. LOL.

It's a DIY mill. In 1993, II got it as a kit, which included the stepper, a driver board (which did just raw coil driving -- not even step/dir!) along with plans for a chassis made of particle board, rails from high quality drawer slides, and all-thread rod as the transport. The s/w that came with it was written for DOS, polling loops and all.

There have obviously been a lot of upgrades over the years: EMC/LinuxCNC in 2004, acme rod for X and Y (Z still uses the all-thread) a lot of chassis strengthening, a real step/dir driver board maybe 10 years ago, and a Mesa card and Raspberry Pi this year. But it still has the same steppers, and the linkages and threaded shafts aren't all that well aligned. Frankly, I'm amazed it all kind of still works. But I have fun with it... when it's not driving me nuts!
