PC requirements for Freecad

Post by dencass7720 »

Hello gents,
would anyone advise or know of desktop computer specifications required for full support of Freecad.
I'm modeling on a laptop that keeps up for awhile and then breaks down and halts progress in an unpredictable state. I've tried several laptops with different results, some can get farther into a model. The specs for this laptop and Freecad's help ' about ' are posted below.

The PC would be used mostly for Freecad, Kicad, and Blender, a CAM package like Cura, perhaps a CNC control like EMC.
I'd rather use an AMD cpu motherboard but am uncertain about a video card ( Radeon / Nvidia ) and RAM size and type. I've read that a Solidworks box requirements are sufficient; 32 GB of ram is minimum, or possibly double that. My present OS is Linux mint. Maybe there's a better linux distro. I've tried 2 other Freecad versions, and switch between them often, including Realthunder, with varying results.

Specs are below, thanks for your time reading this, any replies are welcome and
cheers,
Denis

This sounds to me as if you are well enough equipped for your tasks, so the problem may be somewhere different. Did you ever create a log file by adding the commandline switch --write-log ?

Probably you are trying to make thing too complicated with your models, as FreeCAD (FC for short) is running decently even with old computers (Here I'm using an Intel i3-2100 processor that was discontinued in 2013 and it is working).

Take in account that "core number" will not count too much as FreeCAD is using multithreading only for some (limited for now) things, so probably the "overall speed" of the processor is more important in term of performance than the "core number" at present.

Memory could be important, but usually memory at least in a desktop computer could be increased if needed without too much problems.

If you intend to use EMC probably it is best to use a separate machine,as many suggest to dedicate a separate machine to control the CNC as EMC is performing at his best when using a realtime or a "low latency" kernel.

As @chrisb has told, probably if your machine hangs, hoping I have guessed right " breaks down and halts progress" in your first post, probably there is something wrong in the model that slow down recomputing, but it is hard to tell without more details.

Kind Regards

@ dencass7720 - I had a few problems on a Thinkpad with AMD on board graphics. The OS is MX Linux Xfce desktop.
The problem was the kernel - I updated to 5.14. and have had no trouble since. May be worth having a look at your kernel.

In your original post asked if there is a better Linux Distro. I am on MX 19 AHD (advanced hardware) which is rock solid and a terrific user forum.
