Is it possible to solve the resolution issue with the rotation?
I have tried the config.txt, but without success... what did i wrong?

You can try with the image for Pi5 (Lcnc292_pi5.img) that you find at this link:

forum.linuxcnc.org/9-installing-linuxcnc...i-5?start=170#295779

you have infected me, now i want a robot too

If you have a Rpi4 give it a go.

If you have the choice between a 5 and a 4 go for the 5.

If you do go for the 5, I'd suggest against using the Rpi5 image, as much as Rodw has put into it there are some nice things missing, installing Linuxcnc & a RT kernel isn't that hard on a Raspios image.Actually building Linuxcnc on the RPi5 is pretty quick, if you need to go that way.

If you haven't got a Raspberry Pi on hand and space isn't a issue you'll get more bang for buck with SFF system.

I have a 3D printed robot, 5-DOF (Melfa based) I'm planning on running off a Rasberry Pi 4, running Axis or similar GUI, visMach, over Ethernet to a Mesa card. 

Am I asking too much of a Pi?  What memory size would I need, knowing more is better but not always necessary. 

 

I don't need a lot of I/O so would the 7i96 work just as well as the 7i96S?

Hello.
I'm newbie linux and RPi5.
I did the connection with the Mesa card.
I also have a 10.1" IPS Touch display with resolution 1920x1200 @60 Hz + audio speakers.
But there is no sound, the resolution is only 1920x1080, no possibility to rotate the screen and can't find the grub (/etc/default/grub in sudo nano says it's a new file).

I'm hoping for your help.

Thanks for the reply !!

I did sudo apt update and upgrade.

Hi Rod, I was hoping for your reply since I followed your steps for installing Ethercat. I have successfully installed and able to detect slaves as well.

Also I have created udev rule so that I don't have to give permission everytime, but everytime I reboot or start rpi4 "/dev/EtherCAT0" vanishes !!

I have found solution from the last post of "Ethercat installation from repositories":
root@raspberrypi:~# /usr/sbin/ethercatctl stop
rmmod: ERROR: Module ec_master is in use by: ec_genet
root@raspberrypi:~# rmmod ec_genet
root@raspberrypi:~# /usr/sbin/ethercatctl stop
root@raspberrypi:~# /usr/sbin/ethercatctl start

After following this commands I am able to see "/dev/EtherCAT0", can you please help me with this so that I don't have to follow above commands?

Thanks !!

The RPi4 spi driver doesn't use the spidev device, it's not quite up to realtime usage. Linuxcnc unloads the driver used by the RPi4 and use it's own driver.

Here's some info
linuxcnc.org/docs/stable/html/man/man9/h...#SPI%20CLOCK%20RATES

Hello, looking at the SPI speed between the Pi and a Mesa 7C80 host, Bookworm 12 iso.  The manual has little to say about SPI speed:  www.raspberrypi.com/documentation/comput...erry-pi.html#speed-2

If the `xxd` tool is added, this can be run to see the current speed:  xxd -pd /sys/class/spidev/spidev0.0/device/of_node/spi-max-frequency
In my case it returns 0x07735940 which is 125MHz.  Seems pretty fast already.

Is the SPI speed solely controlled by the app, or can we tweak it somehow?

E: Unable to locate package linux-headers-4.19.71-rt24-v7l
E: Couldn't find any package by glob 'linux-headers-4.19.71-rt24-v7l'

I want to install etherlab master on raspberry pi while installing get above errors please provide any solutions for Above errors
 

Yes, any that has simple buffers and not optos on the outputs should work
The pinout is for this very common BOB:

www.forum.linuxcnc.org/media/kunena/atta...it-408-1000x1000.jpg

But almost any should work.

Would any inexpensive aka chinese "BOB" work? 
 

Tried to satisfy the grisly requirement of old Bullseye build `python << 3.8` to update 2.9.0; gave up, moved back to new Bookworm build.  

On current Bookworm, `config.txt` was in /boot/broadcom, enabled `dtparam=spi=on` and that seems to work, thank you.  Was then able to complete upgrading `linuxcnc-uspace (1:2.9.2) over (1:2.9.1)` successfully.  

Any chance we can try to get VNC working on it?  Not for everyday use; just for setup and configuration.  It would be much easier to work on the config from a workstation rather than the touchscreen. www.waveshare.com/product/raspberry-pi/d...5.6inch-hdmi-lcd.htm
