Muzzer how problematic has it been to vibe code programs. I am thinking of trying it on a few ideas
I have floating around in my head. I have been learning Python coding but it has been a frustrating 
journey to say the least. I'm also using Raspberry pi zero 2w so that may have something to do with it
And as luck would have it I am thinking of using Claude Code.

Hi everyone,

I came across a piece of CNC controller hardware running LinuxCNC. Does anyone recognize this setup or know who makes it?

I checked the system over SSH and found:

- Raspberry Pi Compute Module 5 Rev 1.0
- 2 GB RAM and 16 GB eMMC
- Debian 12 Bookworm
- LinuxCNC 2.9.3
- PREEMPT_RT kernel: 6.6.54-rt39
- CPU configured to run at 1.8 GHz
- Realtek RTL8111/8168 Ethernet controller using the ec_r8169 EtherCAT driver
- EtherCAT master 1.5.2
- WCH USB device (1a86:5537) using a custom ch37x driver, with /dev/ch37x0
- PCF8563 RTC
- Connected touchscreen

The EtherCAT master is detected, but its link is currently down and no slaves are connected.

Does this look like a known commercial controller or a custom carrier board? I would appreciate any information about its manufacturer, model, hardware revision, or available documentation and LinuxCNC configuration files.

Thanks!
 

I am installing a M.2 SSD. Can I copy my current boot image from the SD card to my SSD?
I am running this on Raspberry PI5

thanks for your help

Open each project, on the right side click on "releases", then click on the version you want for Linux or Win or...
Several packages for Linux usually, so choose first for aarch if using Raspberry PI, or X86_64 as .deb or as .appimage, where appimage does not install just make it executable in permissions and double click, or use the deb to install with gdebi.
Did not test, just downloaded all as they might disappear since they are all free versions of very expensive software from a very nasty company.

I am configuring my CNC with a 7i97t, but I don't have that problem. I have a Mean Well 5V 10A power supply with a ground connection for the Mesa and the Raspberry Pi 5; the Mesa needs to be grounded near the RJ45 jack, where it is marked "frame ground."

 I'm having an intermittent issue with a Mesa 7I97T on a Raspberry Pi 5. Occasionally CR7 comes on and stays on until I reset the board.The 7I97T is powered by a Mean Well 5V PSU with no earth connection. The 5V negative is floating, and I measure about 100VAC between 5V- and cabinet earth.Does anyone know what specifically causes CR7 to latch on like this? Is there anything in HAL/HostMot2 I can log to find the cause?Also, should the 5V negative normally be bonded to cabinet earth, or left floating?
Thanks all!

Thanks for the information.
I`m sure there are some facilities, but it`s probably only worth it, if your device costs several hundred dollars or is not available anymore. Google told me that simple repairs start from 120$ and more. A bit too much, unless I can be 100% sure that it works afterwards.

I`d love to send it to Mesa directly, but last time i wanted to order two cards, the shipping calculator presented me with a 250$ shipping fee. Todayy it`s 98$, but import taxes and tolls allways work in mysterious ways according to my experiences, so I refuse.

If nothing works, I can still use it as a huge I/O expander with a second ethernet port. I saw a video on youtube, where they connected two ethernet cards to the host with an ethernet switch. I think i read that one should avoid switches in favor of a direct connection, but my Raspberry only has one ethernet port. I will probably try it, if i order a new 7i76eu.

Anyway, thanks for the help.

After running a few tests, it appears that, in my case, the problem was caused by a missing software package. Installing gir1.2-rsvg-2.0 fixed the issue for me.

It is also worth mentioning that I installed Glade and configured it to use GTK 3.16 and WebKit2GTK 2.28.

For reference, I am running LinuxCNC 2.9.8 RMD on a Raspberry Pi 5.

Hopefully, this helps anyone experiencing a similar issue.

Is it a Pi5 or 4b? the 4b was always a bit marginal but some say the 5 is flawless for them.

You could try the Respberry way perhaps. Once you get the RT kernel sorted, just compile linuxcnc

forums.raspberrypi.com/viewtopic.php?t=396623

I tried this method (but did RIP instead):

forum.linuxcnc.org/9-installing-linuxcnc...th-preempt-rt-kernel

and the latency was horrid. The thread is from Dec 2022 thought it seems, so maybe there is a better way?

The latency isn't very good on the 2.9.8 image from the downloads page either, but not as bad as it was following the above guide. Maybe that's to be expected?

Everything just feels sluggish, and "jerky".

I created the original 2.9.2 image, but have not touched it since. I don't have a pi to do anything further. I think Andy may have rebuilt later versions.
We had no choice but to build the kernel from the official pi source back then.
I think there could be better ways to do this as preempt_rt is now supported.

I would not worry about it just use it. Keep a spare SD card preconfigured. The only thing you need to do is keep a copy of your ~/linuxcnc folder

I've had a Pi4B running for 4 years on a standard 16gB SD card and it never failed. There is far more transactional data happening there.

But surely someone knows who does it.
