Hello,
I am installing ethercat but the communication light with the drivers is not flashing and it is not communicating with the drivers.
raspberry pi 5 
rpi-5-debian-bookworm-6.12.11-arm64-ext4-2025-01-27-0140.img.xz - linuxcnc 3.5.9
I used to use linuxcnc 2.9.3 and there was no problem.


 

Heh. I would have to say probably "yes", to both. LOL.

It's a DIY mill. In 1993, II got it as a kit, which included the stepper, a driver board (which did just raw coil driving -- not even step/dir!) along with plans for a chassis made of particle board, rails from high quality drawer slides, and all-thread rod as the transport. The s/w that came with it was written for DOS, polling loops and all.

There have obviously been a lot of upgrades over the years: EMC/LinuxCNC in 2004, acme rod for X and Y (Z still uses the all-thread) a lot of chassis strengthening, a real step/dir driver board maybe 10 years ago, and a Mesa card and Raspberry Pi this year. But it still has the same steppers, and the linkages and threaded shafts aren't all that well aligned. Frankly, I'm amazed it all kind of still works. But I have fun with it... when it's not driving me nuts!

Thanks for your input. Keyboard input is USB, so meh, not a lot that can be done about that.

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.

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

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

Hello gentlemen !

Im a Newby and want to run a CNC-mill with a Mesa 7i76E and a Rpi 5.
I have  read the thread and think a RPI 5  with 8 GB will be  the right choice for
bookworm and the mesa. The 16 GB RPI5  won't work or is there any kind of news ?
The freason for the question is that i have to buy a RPI but which one is the best opinion and why ?
Can you help me ?

Thanks   a lot

i was able to bench test the image with the ethercat master installed from the repositories and it works. The only thing i found peculiar was that when jogging with the keyboard i could notice some random jitter in the drive. This did not happen with the amd64 cpu i was using before. I suspect this could just be an issue with the keyboard input on the pi though as that jitter is not present with commands from the MDI

Hi
i think you didn't install the NVMPG component here

I thought it was optional.
Do I have to install all of these then?:

sudo halcompile --install ./Remora-eth/remora-eth-3.0.c
sudo halcompile --install ./Remora-spi/remora-spi.c
sudo halcompile --install ./Remora/remora_lpc.c
sudo halcompile --install ./NVMPG/nvmpg.c
sudo halcompile --install ./PIDcontroller/PIDcontroller.c
sudo halcompile --install ./PRUencoder/PRUencoder.c

I don't have a raspberry

Thank you so much for your precious help

No need for a base thread with an external motion controller.
I run mine with a NVMe drive, yeah boot is really fast, I've been playing a around with custom hardware and hostmot2 firmware over SPI. ATM I'm working on a ethernet board to replace the SPI\EPP board that mates with the fpga board I'm using.

If you could add your Etherent mods to the thread linked below it would be great, trying to have a one stop place for all issues/suggestions and such.

I think the raspberry pie five and Mesa set up is really quite brilliant. It’s very compact, and boots up really fast. The only negative i have found is that it’s difficult to put an external Wi-Fi antenna on the pie. If the pie is inside a metal box, it won’t connect easily to a Wi-Fi router. You can get around this by using an external Wi-Fi dongle. Or move the excess point and pie closer together.

The reason I was running that test was because packets were being lost between the raspberry pie and the Mesa board. I couldn’t figure out why. It was suggested to change a setting (I forget which one, but it is documented on The Forum) and after that there was zero packet loss.

Hallo PCW, 
ich habe noch einige andere Einstellungen versucht aber ohne Erfolg.
Eigentlich ist das Hobby fräsen und nicht Einstellungen in Linux CNC zu testen.
Deshalb habe ich überlegt einen Raspberry Pi 5 8gb zu kaufen. Jederzeit verfügbar, ein fertiges Image, kein raten / testen, passt bequem in den Schaltschrank. 

Hältst du das für sinnvoll?

Grüße Erwin 
 

Whole bunch of answers here and the appropriate place to discuss it.

You'll have to give a description of your setup, what image are you using, what is the latency & ping times.

Hello, unfortunately I don't have a contribution to your CAM system, but I do have a question about the Raspberry Pi 5 and Linux CNC On the current PC I have problems with the latency, especially in the Ethernet connection to the 7i96s. Unfortunately, this always leads to unexpected stops of the machine. The last PC was no better and I don't want to buy a third one that will cause problems. My hope is that the Raspberry Pi 5 will work easily and without problems, even if it is a bit more expensive than a second-hand PC. Replacement would also be possible at any time. Now to the question What are your experiences with the pi 5 and which version are you using? Which SD card? Any special settings? Thank you very much Greetings Erwin
