RPI4 Raspbian 64 bit & LinuxCNC
To avoid the problems of compilation and updating I prepared the image of the experimental version of which I spoke in this link.
Get a new SD, install this ready-made image and try with the Mesa card.
Let us know.
tried the image and ran my gcode 5 or 6 times without getting the "hm2/hm2_7i96s.0: error finishing read" problem, so that was great!
i did get a single joint following error, so will look into that some more...
thanks again to all of you for your help
I am a new LinuxCNC user. Over the past weeks/months I read a lot about LinuxCNC, and tried it out on my Windows PC via a virtual machine (with no hardware attached). I really like the software and decided that I am going to use it in my CNC machine. As I don’t have a Linux computer I bought a Raspberry Pi 4 GB.
It took me a while to get LinuxCNC running on the RPi. The dedicated ISO from the LinuxCNC downloads section didn’t work, but after some frustrations I eventually got it solved by using linuxcnc_book.img. The explanation from Elovalvo was helpful for me. Thank you very much for that!
Unfortunately I soon ran into the next issue, as I have difficulties installing QtPyVCP.
I tried to install the software dependencies with the command listed at the bottom of this page:
This gave me a list of error messages as attached on the screenshot.
However I continued with installing QtPyVCP, which did not generate any strange messages, but in the end it did not work so I guess it has something to do with the software dependencies.
My background is that I have quite a lot of experience in Python scripting (including graphical user interfaces) and a bit of Windows PowerShell, but apart from some very basic usage I am not at all familiar with Linux.
Actually it makes me doubt whether or not I should proceed with the Raspberry Pi approach, as I got the feeling that this is not the easiest or most robust way of using LinuxCNC… The software made me very enthusiastic when I used it on a virtual machine (without any hardware attached). But since I got the RPi things don’t go as smoothly as I hoped, maybe the learning curve is too steep for someone without Linux experience?
I was planning to order a Mesa 7C81, but as this card is dedicated for RPi I am still somewhat hesitant about that.
Does someone perhaps recognise the QtPyVCP issue and knows how to solve it?
Looking forward to your replies!
After floundering on-and-off for years (no joke) trying to get a functioning install, this thread hands me a functional solution on a silver platter ! I've somehow always managed to find myself with some sort of hardware compatibly issues - this time, just as warned, the official SD image doesn't play nicely with my Pi4 8GB . But (!), as I've already said, the image supplied by elovalvo (on page 16) is showing more signs of life than anything I've managed to procure on my own:
I have a some ways to go to get it to work with my Mesa 7C81, but I needed to make an account to say THANK YOU to elovalvo ~
This is now superceded as its in the 2.9 documents now.
Please refer to this link instead. linuxcnc.org/docs/2.9/html/getting-start...etting-linuxcnc.html
Annoyingly Chrome is not supported on any ARM hardware. This may install an open source version for you
sudo apt update sudo apt install chromium-browser -y
I'm not sure if this picks up your Google profile and al your bookmarks etc.
