I apologise for the previous answer by the previous user, it really doesn't address your issue..
I'd go for this

I've been using the H3 Plus for a few years and had no issues with it. The only thing you need to do is use the non-kernel realtek drivers for the nic. I'm pretty sure Rod from the forum also uses one.

Waveshare also have this setup

I'm currently running a mill with the C box but you're situation would be better suited to the A box.
I like the fact the case and connectors are well integrated, full size HDMI ports, all but the power switch, Serial console connector, and the connector to power it from a non-usb supply (meanwell would be a good choice) are on one side.
The only caveat is that the NIC is a realtek based one, but as long as the cnc stuff goes thru the RPi interface everything should be ok.

Langdons would please provide an answer relevant to the question, the user was looking for a small form factor PC, almost a similar size as a RPi5.

This is awesome! I actually just today started wiring up the retrofit of my EMCO Concept Mill 155. Newbie to linuxcnc, so it’s been going slow so far. Would you be open to sharing your setup files? I’ve got the same tool changer, would love to see your code for that.

I'm a bit concerned about the STEP/DIR wiring.

It appears that the thick white wires are grounding the STEP- and DIR- pins
This should never be done as it shorts out the STEP- and DIR- pins
possible damaging the driver chip.

If STEP- / DIR- are unused, they should be left unconnected.

Hello.

I Know that MPG mode is the default mode at startup for whb04b-6.  So When moving the handwheel  the FeedRate Override changes untill we press Cont or Step yellow button

Is there a way to start in Continuos o Step mode?????
