With the Pi4 its maybe a little bit better.
The arm core is connected to the internal AXI bus

It's not a preference, it's an artifact of the situation: CNC machines

What we have with LinuxCNC is "legacy software".The hardware hardly
matters.This software was designed before the modern era, before
computing power was nearly free, back when you really needed a PC just to
make a few motors move. The problem with LinuxCNC is that it requires a

The fact is that "this OLD CRAP" works, just like the crappy old "Soviet
era technology to send American astronauts to space from Russia".

Correct, a new one is ... new. Which means it uses currentl
I see this tread circling around the same issue as the one after I
posted my comments on this subject matter when I was exploring possible
options for new CNC machine.

This problem of old or new hardware isn't unique to LinuxCNC PCs. This small
$10 moisture sensor for a Maytag Combo Washer/Dryer has been discontinued. I'm
waiting for the epoxy to dry but ultimately if I can't remanufacture it with
glue or 3D printing then we're out $1K for a new machine.

Even cheap Hardware from resellers are minimum an I5 5gen for 200$ max.
this Machines are working fine with Preempt rt and latency in the range of

Realtime but the arm core have no acces to any IO. its all handled by the Vcode

i think drop support for Computer Museum Hardwar
It tried to run the BBB with LinuxCNC back in 2013 and the video
performance was too poor. Frame rate was way too slow. We had better
success with a 4-8 core Allwinner SOC and FPGA.
I tried the Rpi4 last summer and the 4K video was way too unstable. Plus
I need two 4K screens to run the resin

Lots of reasons to use new hardware, NVMe is one of them.

It was free from when we cleaned out the FIL's place. The one before
that was in the heap of rubble of retired computers. No reason to buy
new to run a router.

As for new hardware, people seem to like to run Machine Kit on the Beagle
Bone Black (aka "BBB"). Its a tiny credit card size computer that can run
Linux.I think the BBB is actually more powerful than those old PCs and
it can run off a phone charger.
If you want to run LinxCNC on "modern" ha

Hi,
For reasons I dont understand, many people prefer to use extremely legacy
hardware to run linuxcnc.
the hardware list in the wiki is extremely outdated, and there is no real
recommendation on what to buy currently.
just for fun I tried to run it on modern hardware, and it worked really
well.
