At a guess, the image you have used is 32 bit and the Pi4b is 64 bit
Please use the image on the linuxcnc downloads page and not the comments arouns seting wifi etc.
 

hellow sr. hakan.

Congratulations on your post. I had an initial problem.

I downloaded the image and used the raspberrypi image to save it and it didn't start. Mine is a raspberrypi4b.

O erro "CPU 0 not supported"

Hello, nice work.

I'm installing a 5 axis XYZBC machine driven by a berak out with a parallel port --> I want to switch to an ethernet port and raspberry pi 4. I want to add position sensor feedback at least on the B&C axes.
I'm trying to install linuxcnc 2.9.3 on my raspberry Pi 4 under raspbian. Impossible to compile/install the RT patch . see that you have a version “Linux pi 6.6.44-rt39 #1 SMP PREEMPT_RT Mon Aug 12 21:10:13 AEST 2024 aarch64 GNU/Linux” .
Can you help me with this installation?

Thanks for your help
 

Hi everybody, as the name suggests this is a guide for people wanting to install and start playing around with Riocore.
For those that don't know anything about Riocore you can read through the original thread :

www.forum.linuxcnc.org/18-computer/49142...d-on-fpga-ice40-ecp5

This guide is aimed at people that aren't linux guru's, that want to have a try at this awesome LinuxCNC software/hardware and that might struggle like I did...for weeks...to install it and get it going.

Credit to meister, the guy behind it all, he has done an impressive job of getting all this going.

Another credit to ColdTurkey, his idea of using the LinuxCNC live install to setup software/hardware in the Remora thread is what I based my approach on, this way everybody has the closest starting point possible.

This guide will focus on getting everything going for the Gowin Tang Nano FPGA, and meister's Tangoboard, once you have this going you can select other FPGA's and boards as you wish. You will most likely need to change the FPGA programming side of things with other FPGA's.

OK lets begin...
This is for a normal PC, I will have a look at a Raspberry Pi install sooner or later hopefully.
Download and install the latest live install of Linuxcnc, then open a terminal

sudo apt install git
open firefox, skip all start steps, start browsing, google search gowin eda
open page, (first link for me) create account, only email and password required
once logged in, select support, then Gowin EDA Home, then Download Gowin EDA
select software for Linux tab
select the one that says education, (click over to the right)
  (at the time of writing this it is the 7th option down)
open File system, navigate to Downloads, right click and select extract to
click on the little folder icon and select Home then extract
go to the folder in file system, right click rename folder to gowin
    its easier to type out later
open terminal, enter these one at a time :  
git clone github.com/multigcs/riocore.git
sudo apt install python3-pip
sudo apt install python3-yaml
sudo apt install python3-graphviz
sudo apt install openfpgaloader
sudo apt install python3-pyqtgraph

That last one takes a while to install

Now we setup the USB programming :
in terminal still,
cd gowin/Programmer/bin
once you are in that folder type and enter :
sudo ./Gowin_USB_Cable_Installer.sh
sudo make

reboot machine

open terminal

type and enter :
export PATH=$PATH:home/your_user_name/gowin/IDE/bin

in my case my user account is "me" so I type:

export PATH=$PATH:/home/me/gowin/IDE/bin
export PATH=$PATH:/home/me/riocore/bin

change to the riocore directory
cd riocore

now type
PYTHONPATH=. bin/rio-setup riocore/configs/Tangoboard/config.json

This should get you up and running, now there is lots to learn about setting up a machine but hopefully this will take the heartache out of starting.

Now things can be a little weird, I believe the Tang Nano needs to be plugged in at reboot, sometimes it won't flash properly, I cannot honestly say I have got it 100% sorted but if anybody finds a better solution we can edit this to suit.

Good luck
Russell.

Hi Guys, thanks for you time.
I've been doing my own search, but without much look to find some tutorial that explain me how to configure files, I know that something may have to be change on hal and ini but after that no much idea. If you guys could explain me what file have to be re-writted or changed with some explanation would be appreciated . 

details: 
sim axis vismach 5axis.table-rotary-tilting
using vasmich "would like to design my own machine is that is posible"
7c80  "hm2_rpspi"
connection /dev/spidev0.0
linuxcnc 2.9.3
raspberry pi 4 

uname -a 
Linux pi 6.6.44-rt39 #1 SMP PREEMPT_RT Mon Aug 12 21:10:13 AEST 2024 aarch64 GNU/Linux


let me know if you need more details

thanks!!

I use Raspery on Pi5, there are no problems, it starts automatically without a password when the first power comes on. While the CNC is running and processing materials, a password login screen appears occasionally, but the CNC does not stop and continues to work. What causes this encrypted login screen to appear?

AMD64 and Raspberry Pi 4??

everything is working now ....

I really think it's a miracle!!!

I tried
enable the optional hardware interfaces
dtparam=i2c_arm=on
dtparam=i2s=on
dtparam=spi=on

everything is working now.

Thanks all you guys for your help.

I finally managed to get all the parts & wiring done. Settled with a 7I97T and a 7I84 controlled by a Raspberry Pi.
Crazy to think that the little Pi is probably 10x more powerful than the huge Siemens controller.
 

I implemented the tool changer via classicladder and it really works like a charm, pretty happy with it.

Now I just have to tune the PIDs for the servos and I can run some test parts. The Fusion360 CAM section for turning looks way simpler than for milling, pretty much just 4 operations, so I think I'll pick this up quickly.

Just had this issue the other day. I don't think you have to compile from source if you don't want to. I'm on a Raspberry Pi 5.

It looks like EtherLab changed the name of their distribution repo from IgH to EtherLab. Check out the new location on this page under the Debian section.
etherlab.org/en_GB/getting-started

Relevant instructions:
export KEYRING=/usr/share/keyrings/etherlab.gpg
curl -fsSL download.opensuse.org/repositories/scien...ebian_12/Release.key | gpg --dearmor | sudo tee "$KEYRING" >/dev/null
echo "deb [signed-by=$KEYRING] download.opensuse.org/repositories/science:/EtherLab/Debian_12/ ./" | sudo tee /etc/apt/sources.list.d/etherlab.list > /dev/null
sudo apt-get update

You will have to remove the sources list of IgH if you don't want errors during apt updates.

I don't know if you guys rebuild images between releases, but if it's possible to remove the IgH repo in favor of the EtherLab it may be helpful.

Thank You very much

7c81 configuration with 7I77 on P1, MX4660 on P2 and just GPIO on P7:

 
 

Currently I'm using that:
freeby.mesanet.com/7c81_mx4660x2d.zip

Can I ask You to make it in way:
P1 = 7i77
P2 = MX4660
P7 = GPIO
if it's not plenty of work?
I'm asking because that will help me with arrange space in cabinet.
Thank You in advance

and in connection with photos above
I manually added config for pncconf for 7c81 and 7i77 and mx4660 but something is wrong in comparision to 5i25 + 7i77:
  i cant find where is mistake, everything looks ok, maybe You know?
 

I'm not sure what you are suggesting

What firmware are you using currently?

I would probably make firmware something like

P1 = MX4660
P2 = 7I77
P7 = GPIO
 

I'll appreciate it. I'd like to connect via P1 because i leave it for encoders in future and time has come (based on other users experience). I already use P2 and P7 for communication with mx4660.I've tried to add configuration to pncconf but TXEN2 TXDATA2 and RXDATA2 don't want appear, do someone know what I'm doing wrong?
