I would suggest a normal x86 PC with 4 cores, 4 GB RAM (eg Celeron J1900 or above). I3 and I5 seem OK too
My 16 core i7 on my desk is way over the top

I think technically its 8 core, 16 threads but it reports in with 16 on linux (including in htop). Frightened me!
All I wanted to do was get rid of Windows!

Oh an 10700, that has 8 P cores and 8 E cores, meaning 8 performance and 8 efficient cores.
That was just another Intel f@k up as for a while those 8E cores could not be used under Windows and caused stability issues, lasted nearly a full year till they figured out how to use those.
Not that they do much anyway, but they do help a bit.
I have gone full AMD several years back, will not buy Intel ever again.
They (and AMD not being able to compete for quite a while) single handily retarded PC advancement for nearly 20 years.
For anyone wanting to rant about this, don't, just have a look how far have graphic chips gone in that time frame.

Rod, Thanks for the update. I am trying again from the start on a i7 hp g2 mini. I have come across an error while compiling

Code:

cnc@cnc:~/dev/linuxcnc-ethercat$ sudo make install
make[1]: Entering directory '/home/cnc/dev/linuxcnc-ethercat/src'
mkdir -p /usr/lib/linuxcnc/modules

cnc@cnc:~/dev/linuxcnc-ethercat$

I read the part you wrote "becasue you have not installed halcompile (in shipped in linuxcnc-uspace-dev)" but I for sure installed linuxcnc-uspace-dev. As you can see from the error, there is trouble finding ecrt.h even though the find command shows the file here /usr/src/ethercat-dkms-1.5.2/include/ecrt.h.

***EDIT... I forgot mention that i did try the spoiler and it didnt change anything also i tried adding a symbolic link with this line but the error is still the same

Code:

sudo ln -s /usr/src/ethercat-dkms-1.5.2/include/

Do you know where i should go from here?
thanks
