Recommended PC configuration: CPU and Motherboard (Q1 2020)

Right, but qtypyvcp uses VTK that needs a newer OpenGL version
so Axis runs fine on older PCs but qtypyvcp needs newer hardware

Did not know that and never noticed as i use Axis gui.
Thank you.

Axis uses OpenGL and will not work without it.

I am aware of that, was not aware that VTK is directly or indirectly related to OpenGL.
In that case, i have not noticed, i use Axis GUI, and it works on PC's and Laptops up to 15 years old.
Or maybe i did ! Hmmm, when i test computers i start axis gui and move the logo on the view, zoom in and out, and check how quick it responds. Any lag and i do not use that computer for machines.
That might be it.
Thank you PCW and Todd.

If you only need one, don't need guaranteed supply, and don't want a touch-screen:



I have one as my LinuxCNC test machine. Latency is <7000 preempt-rt and <5000 RTAI. The parallel port works with LinuxCNC and it has two internal PCI slots.

Mine is permanently set up with a 5i25 + 7i76 in the PCI, a PCI parport card and a 7i43 on the onboard parallel port and a 7i80DB on the ethernet port.

I join the discussion with a similar question.
At the moment i'm running my 3d printer through the parallel port on an old HP P4 workstation. All good, but it started showing black screens ( mid print, after 24 hours of printing ) and i crashed the machine 2 times due to the UI freezing in jog mode.
So it's time to change it. At home i have a Pentium D pc that has very good latency numbers (but no parport, not an issue because i just ordered a mesa 7i96), but i'm tired of old, hot, constantly swapping PCs. So i was thinking about removing the old motherboard / cpu / disk from this pentium D machine and replacing everything with something like this:
www.amazon.it/gp/product/B079GHR8L9/ref=...A14O09FCGSM9B3&psc=1
Does anybody have any experience with this cpu? The price is incredibly low ( i'd get mobo with cpu, ram and ssd for less than 130€), it's fanless, 10W instead of 95... I just need someone to tell me if it could work with linuxcnc uspace (i'm currently migrating to 2.8, and i'll adapt my configuration to the mesa board as soon as i get it).

It looks good.
I use a J3355B with a 2 Core Celeron with a 2.0GHz base freq burst is 2.5GHz
The J4105M has a 4 Core Celeron with a 1.5GHz base freq burst is 2.5GHz

Hers a search on the forums regarding the J4105

I already search a little on the forum, this in particular doesn't sound very promising forum.linuxcnc.org/18-computer/34992-mot...mesa-7i80hd?start=20

The Mint ISO's I'm working on use 4.16.12-rt5-kona-rt

It's a bit hard to diagnose with the comment "my graphics are total crap".

Using that kernel with on T530 Thinkpad I can get 1600x900 with a NVIDIA Corporation GF108M [NVS 5400M]

I'm going to spin up a new ISO shortly I'll test on my J3355B and see how it goes, may be a indication on how it goes with your board.

I am using that same kernel/mint/ on several (over 10 right now) PC's and laptops and a HP tablet PC, all of them work perfectly.
The graphic problems are in RTAI version, not the Kona-RT version.
RTAI on some hardware has some issues, on some it works happily.

Ok, so it should work fine with stretch / preemptRT.
Do you have a better alternative? Otherwise I might order that today or tomorrow.
I already have case and psu, so I just have to order that board, some ram and an ssd (you can find 120GB crucial ssd's for lesse than 30 euro 0.0).

I received the motherboard today!
On a fresh linuxcnc stretch installation the graphic was indeed terrible (stuck on 800x600).
I updated the kernel through synaptic to 4.19 rt (stretch-backport).
Straight away i booted with 1080p resolution.
I still have a few issues though, i get quite high latency spikes related to graphic load (eg: when resizing a browser window) up to 170'000 ns.
Any idea? It's probably a driver issue, you can see that the gpu isn't performing how it should also when scrolling the browser.
