So after a few battles, i finally have the mesa board talking to LinuxCNC. I have movement. I have proximity sensors all connected and working. I have coded HAL to get the right distance traveled.

Still to go - laser pointer, z axis, air scribe, water table & tank, paint, clean out shed, concrete for shed floor to hold it.

I still have a glitch in the screen that shows what is being cut, and i get no preview of what i load,
 

OK so to answer my own previous question basically I'm stupid, I hadn't set ownership to my user account, so Linuxcnc couldn't write to the var file, and most likely create it in the first place, which is why it was missing.
I had thought I'd done it but obviously I hadn't or maybe did a typo at the time. I followed the Docker install instructions as per the wiki instructions if anybody else is having the same issue.
Big thanks to Meister for creating this and thanks to everybody else supporting.

Never came across an M17 bolt (but M17x1 and M17x1.5 taps are available)
Is the hex of the head 17 mm?
In that case it would probably be an M10 bolt as smc.collings already guessed.
M10x1 is common on rear axles for bicycle hubs, so that would be easy to confirm, by screwing the bolt into a nut from a bicycle.
Taps for it are "findable" e.g. Yamawa, Gühring, SUS, Corai, Regal come to mind.


Should it be M10x1 I would probably just make two slots into a hardenend bicycle axle with the angle grinder, then carefully screw it in with some cutting oil to clean up the thread.

My system is basically :
- installed from linuxcnc usb stick
- removed linuxcnc using synaptic
- installed RIP linuxcnc using documentation.

My locale is SK (Slovak)
i will try to install RIP in new, EN locale.

ATC action!



Should have animated the eyes. Oh well, next time.

No smoking gun yet, but it seems master branch will not load your program properly - and showed other bugs in master CL.
I do see your program uses 150 arithmetic expressions, which is the max you have available.

I got a sample program to use jump coils - see example.
(clicking the %B0 in the Vars bit window will change the #QW0 output from 1 to 5)

 

OK.

Wasn't sure about a real time kernal, so check and have "6.1.0-28-rt-amd64".

Have uninstalled all traces of LinuxCNC, and now using the synaptic package manager, have loaded the latest linuxcnc versions.

Start up pnfcof with the mesa 7i96, everything worked.

Still having the same issue. estop is red, cant be unclicked.
Cant select power. left hand side of the screen is blank/glitchy.

Any ideas??
 

Note: Using POSIX non-realtime

Means it's not real time

I don't see this issue on a current RIP build.
Are you by chance using a Wayland desktop and/or a non English locale?
 

Correct, they are visible under /dev/

It is PREEMPT_RT

enabled RT when building.

With regards to the RPi5 images Rodw linked to a new one on his google drive that seems to fix the screen issues. This is the one I used recently with my RPi5.

If the SPI interface isn't enabled mesaflash will give
open: No such file or directory

So I would guess the SPI interface has been enabled and the nodes created under the /dev directory.

The kernel is not going to work anyway since its not realtime

The way I built my RPI5 test system was that I downloaded the RPI5 image
from the LinuxCNC website:

www.linuxcnc.org/iso/rpi-5-debian-bookwo...23-11-17-1520.img.xz

Installed it and then built linuxCNC master from source.

I wonder if something in config.txt could be an issue also... (since the cable and 7C80 seem to work)
