Houston, we have a problem, i ordered the io port expander (mcp23017) in wrong package so28 instead of ssop28, and the zener diodes is missing from the order, and i missed the i2c port pullup resistors from the design this need a littlebit of workaround, but the outputs are working now (tbd 62783). Tested with 5v and 24v without load, i messed up 1 of the w5100s-evb-pico-s usb port by pulling the whole microusb inside out but now this programmed trough the SWD debug port, the positive side is i do not need to printing debug info in the usb serial port.

I can give it a try, could you please share more details on how you got ethercat installed so i can reproduce your setup?

Just gone 3pm here in Sydney.

No something interesting.

I worked on a little project using an FPGA dev board to run MESA's hostmot2 firmware. First attempt was based on the 7c81 using either SPI (raspberry pi) or EPP (best on motherboard based parallel ports). The issue with the board I used is that the EEPROM need to be changed and the headers were already soldered on.
That same hardware can also be used with the LinuxcncRIO project.

Another project I had a go at was modding the 7i90 Smart serial firmware to support 4 encoders to run on a dev board.

For my latest I've grabbed a different dev board (eeprom is correct size & bought with the headers unslodered, but this time I'll be trying a Ethernet interface, chip is same as use on the Mesa products, so no having to rewrite a driver, which requires a couple of steps, first being working out the instructions of the softcore, working how the driver talks to the chip and then how it integrates with the rest.

Some pics, 2x17 ports from breakout boards (mesa 25 pin daughter boards can be used as well) and 4 extra pins for 2 smart serial ports or extra I\O.

First off is the FPGA from aliexpress:
 

The Ethernet board, this is experiment only, the FPGA board sits on top, disregard the type of 2x25 headers they can be changed to suit. Should have the boards in a couple of weeks.
 

One of the daughter boards from the orignal project.
 

Pretty.

cnc@raspberrypi:~$ sudo apt-add-repository "deb buildbot2.highlab.com/debian/ bookworm master-uspace 2.9-uspace"
sudo: apt-add-repository: command not found

Congratulations on your results so far.

I have never tryied LinuxCNC in Raspberry Pi. But, based on my experience in PC based LCNC, I don't think you will ever have any reliability issues running it in step/dir. LinuxCNC is a hell of a reliable motion controller.

 

We would like our LinuxCNC system to control an activity light. This would be a red light on the machine active when the motors are engaged. Does LinuxCNC already have a feature to control such a thing? Where should I look to find the interface?
We are using a Mesa board and a Raspberry Pi. Can I route a control signal through to an output pin on the Mesa board?

Thank you.

Maybe not.. now it stops at:

cnc@raspberrypi:~$ sudo echo "deb buildbot2.highlab.com/debian/ bookworm master-uspace 2.9-uspace" >> /etc/apt/sources.list
bash: /etc/apt/sources.list: Permission denied

Hi guys!

New user here with limited knowledge. Trying to convert an old mill, have a rpi5 and a 7i97T for the job. Planned to use MesaCT to help me with the start of the config, but there is states the 7i97T needs LinuxCNC 2.10.

I've already installed the "Raspberry Pi 5 OS based on Debian Bookworm " from the website, which i'm now trying to update using this post. No luck so far for me!

seems to fail from;

sudo cp -r /etc/apt/*.* ~/aptsudo wget buildbot2.highlab.com/buildbot-archive-key.gpg /etc/apt/trusted.gpg.d

returns;

cp: cannot copy a directory, '/etc/apt/trusted.gpg.d', into itself, '/etc/apt/trusted.gpg.d/trusted.gpg.d'
cp: cannot stat '/home/cnc/aptsudo': No such file or directory
cp: cannot stat 'wget': No such file or directory
cp: cannot stat 'buildbot2.highlab.com/buildbot-archive-key.gpg': No such file or directory

I'm running linuxcnc 2.9.4 (which I downloaded from Debian 12 Bookworm PREEMPT-RT ISO ) in VirtualBox in order to try out the various UIs etc. The actual CNC is being driven from a Raspberry Pi. I'm currently running gmoccapy but I'd like to try out the QtDragon UI.

I found some instructions that said I needed to install linuxcnc-uspace-qtvcp but it's not in the debian repo and I didn't want to start adding random sources without knowing what I'm doing. There are also references to modifying .ini files but there are a lot under sim.gmoccapy so it's not clear which one to modify, and in any case, I thought using QtDragon meant not using gmoccapy.

Sorry, I did not want to upset anybody. It is my fault. Sorry.

Prototype boards arrived.

Unlocking now.

You need to use menuconfig to setup your locale.
