Linuxcnc & the Raspberry Pi (4 & 5) Official Images Only!!!

Wifi setup is by running

Be sure to edit to choose option 5 "Edit wpa_supplicant" with your country code, ssid & password.

To setup network for a mesa fpga Ethernet card, choose option 6 "Edit interface" and modify eth0 to match post above if you have jumpered the board for "FIXED FROM EEPROM"
If you have jumpered for "FIXED 192.168.1.121" replace 10.10.10.100 with 192.168.1.100.

If your home wifi network is on the 192.168.1 network, use the 10.10.10 network for your Mesa card, refer to you card's manual for jumpers to change.

After config reboot
To check the network type in a terminal
Taken from 7i92 Manual

A final note, there is no network notification applet for the desktop, so you will not get any notifications when the network connects, disconnects or reconnects.

I installed LinuxCNC onto a RPi 400 with a touchscreen and GMOCCAPY. It works very well, but something has changed on the system and it is now unstable. LinuxCNC, is locking up after periods of inactivity. Running a Mesa 7i96 board. Wonder if doing another clean install will fix it. Might have had a bad update along the way. Will let you know what I discover....

Ok the description is a little vague.

I don't think a clean install will "fix it". I don't think an update would have anything affect as the kernel,kernel modules and firmwares should not be touched during an update. In all honesty unless you are wanting to update Linuxcnc, there shouldn't be a need to do an update, most updates are just minor fixes that really don't affect the way Linuxcnc operates. The biggest "security threat" to cnc machine is someone getting physical access, and it would be the machine it self I would be the most worried about, blood gets everywhere, it's hard to clean and the injured party may want to blame you. I only will have wifi on when transferring files to the cnc machine, other than that I disconnect wifi.

I think you maybe experiencing an issue similar to what is discussed in this thread. Which it would is not Linuxcnc related, it's the ethernet port going to sleep/shutting down, tho it should be tx\rx ing packets more or less continuously. Yes I know it's a direct connection from the Pi to the Mesa card and the thread mentions switches a few times.

It seems to be somewhat random to which boards are affected but I haven't noticed this on my RPi400.

Tho it might be an idea to check the power supply for the Pi & the mesa card. But if ti was the mesa card "dropping out" you would get notifications.

Dude please don't change the subject, it makes things hard. I check this thread regularly.

I think it is useful to change the title from
"Linuxcnc & the Rpasberry Pi"
to that 
"Linuxcnc & the Raspberry Pi"

Sorry, did not think it would affect the whole thread.

I have a second Pi 400 on my Ham Radio station, so I switched the two keyboards and fired up LinuxCNC on the "new" board.  I let it sit for awhile trying to duplicate what happens.  Basically the display becomes unresponsive to anything.  The cursor moves around, but I cannot select between pages on GMOCCAPY. However I can still jog the machine around using my pendant, so It is still communicating with the Mesa 7i96 board. Also I cannot ctrl-Esc the Pi to access the task switcher, so something is locking up. 

One thing you can try is logging in via ssh, before things lockup, and when they do see if anything untoward shows up in dmesg or any of the other log files.

Does it occur when just running one of the sims from the Linuxcnc menus.

Are you able to use a config that uses Axis, if so does this give the same problems.

Just to confirm your are using one of the images from the downloads page, without an extra packages installed, cos I'm not sure if ctrl-esc gets the task manager. On the RPi5.which is the same apart from the kernel support, it doesn't bring up a task manager.

Before the title was changed, it was mainly to do with the Linuxcnc images, not Linuxcnc on Raspberry Pi OS.


Tommy if you see this can you change the topic heading so it reflects this is support for the Official Linuxcnc Rpi Images, I didn't intend for it to support Linuxcnc on the Raspberry Pi OS. That should be dealt with elsewhere.
I'm pretty sure the original tile reflected that.
