Linuxcnc 2.9.2 and 2.93 images for Raspberry Pi 4b & 5

8gb will be fine. 
Linuxcnc runs happilly in 4 gb on most platforms.

First of all, thank you very much for your work with the images. 

According to everything I found on the net, a pi 5 8GB with SanDisk extreme pro 64gb, official power supply and a Mesa 7i96s should work without any problems? Is that correct?  

Are there any restrictions regarding
- user interface (probe basic, gmoccapy)
- the wireless 6 axis handwheel  

One last question about the cooling / housing.Is a passive cooled case like the Flirc Raspberry Pi 5 case sufficient or should active cooling be provided? My thoughts on this are mainly dust protection.


Perhaps useful for others
Unfortunately, the standard office monitors all have large ventilation slots on the back. I have been looking for alternatives for a time and would now like to use a mobile external monitor (sold as a supplement to the laptop). These seem to be much better protected against dust.

Thanks

Use the official fan & heatsink, it works well and you'll have no issues. I've left mine on for days at a time during the summer in Australia and nothing has gone wrong.

I prefer a wired pendant, connected via a Mesa 7i73. It's solid and you don't need to worry about disconnections. Just axis & step selectors with a hand wheel. Tho Rod does us a fancy wireless one.
