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.

Hi,

Is it possible to create an auto-login for the raspberryPi in order to create a keyboard less system with gmoccapy?

You should be able to set up auto login the same way it is done with an x86 machine as its the OS you are logging into

Hi,
The Linuxcnc 2.9.2 and 2.93 images for Raspberry Pi 4b & 5 are
special OS. The menu-config configuration does not have the option for auto login.

Nothing to do with menu-config. Its all Linux

Rod's the one that has put them together, apart from the RT kernel & the addition of the Linuxcnc packages it's just Debian. Nothing special about the actual OS.

Thanks a lot. This is the info I was looking for.

hi, can this image use traight to gpio too, rp4b board and i made 3,3V to 5V output level converter board use traight gpio output to stepper motor drivers DM556,
and same i build optocouplr board all input opto to gpio can use safety all gpo, not used BOB card or other board, i made diy own in/out gpio to 5V convert board, hope image can use straight all step/dir, enable, signal out to gpio pin. its easy use level converter module can convert 3,3 rpi output to 5V input by stepper driver controller etc, DM556.
same i think can easy use optocoupler module all input gpio pins. 5-24V in to opto and then 3,3V safety to in rpi gpio.
