Glad to hear you're up & running.

Cheers

Brilliant!  I just had GMNOCCAPY up and running for hours without a glitch after making that change.  Believe you nailed it.

Thanks for the great tip.

Hey all,

I ran in the following problem:

cnc@raspberrypi:~ $ designer -qt=5
Qtvcp python plugin found: /home/cnc/.designer/plugins/python/qtvcp_plugin.py
[DEFAULT][INFO]  Logging to: /home/cnc/default.log (logger.py:106)
tool_mmap_user(): tool mmap not available
poll(): continuing without tool mmap data
[DEFAULT.QTVCP.LIB.SYS_NOTIFY][WARNING]  Desktop Notify not available:: org.freedesktop.DBus.Error.ServiceUnknown: The name org.freedesktop.Notifications was not provided by any .service files (sys_notify.py:71)
link (updating variable file): No such file or directory
link (updating variable file): No such file or directory
Segmentation fault

I've followed the QtVCP installation progress and linked the qtvcp_plugin.py but I get this error when starting the designer.
The designer loads without any problems when the qtvcp_plugin is not linked.

Did this occur to anyone before me? Or does anyone has an idea how to resolve this?
 

USB to parallel port not supported at all, don't an option.
Any other USB motion control are not supported.
All supported Mesa boards can be found on their website. You can also browse the forum to see what boards are popular at the moment.
For the DIY route Ollie's Linuxcnc- RIO project is fantastic, well supported and in active development as is Scott's Remora Project.
I've also been working on a setup that uses FPGA Dev board available via AliExpress that runs Mesa's hostmot2 firmware, ATM it only uses SPI interface for the Raspberry Pi or EPP for the PC platform, tho I'm currently working on an ethernet plugin board.
In all honesty if it wasn't so expensive to get items from the US to Australia I'd go with Mesa in a heartbeat. What board just requires at little time researching, coming up with a couple of choices then asking a few questions, the 7i76 boards pretty much have it all.

Might be worth trying in the GMOCCAPY Section, even linking back to the issue in this thread.

Was thinking about this last night, it may be worth looking at this regarding swap. Just on the off chance.

So after further testing I can tell you that the axis GUI is rock solid. No issues when left for extended periods of time.  When I get some more time I will use SSH to poke around when running GMOCCAPY.

Thank you for the images. There are a few kernel/driver changes I'll be working around, but the experience was super easy.

Backstory: I tried to upgrade my successful installation, and the pi wouldn't boot, giving the "missing firmware" error. I copied my existing linuxcnc config files using another Linux system. I installed your image on windows. I copied the config onto the new SD card. It booted and nearly all was well.

Thank you.

Like I said before, log in via SSH, wifi it would have to be, run Linuxcnc as you would and if things lock up and SSH is still good start with dmesg then looking through logs.
Also it would be interesting to know if this happens when using axis.
A lot of the investigation will have to be done by yourself.
Obviously it's not a complete machine lockup, as you reported your pendant can still be used to move the machine, so Linuxcnc is able to receive and transmit to your mesa card.
What happens when the machine is left idle without a Linuxcnc session running ?
If are unable, unwilling to address the queries in this post and my previous post I'm afraid I can't offer any help.

I used the image from this page. The only other thing I added was Filezilla, to transfer files to and from my PC where I generate the gcode files.

And yes, pressing Ctrl-esc brings up the main rPi menu where I can select to run other applications. If I have LinuxCNC up, I can use that to launch Filezilla without exiting LinuxCNC. That functionality has to my knowledge always existed in the image.

Is this OK or any better idea?
