Is this the right place to ask another question? If not I'm sorry.
New to LinuxCNC and after messing about with the pi interface went out and bought a 7i95T.
So I'm trying to set it up even though it's still in the post. Default Metric, 7i95T XYZ and I get a set of good defaults. I can go through and add all my numbers or not and it builds.
However when I reopen that ini file my XYZ is gone and I just have Z and that is in as Drive 0.
I must be doing something dumb as this would have been noticed long ago.
Please tell an old man with a mill (but no python although time-served on C++) what he has missed so I can improve rather than re-enter stuff. I got MesaCT from the github page yesterday.

...and Bjarne says that it's been added. Hopefully this won't be a problem in the future.

Never had a problem, works everytime. Here's some set-up notes. 

Hello
I couldn't really continue with setting LinuxCNC up. But I want to probably use a touchscreen to interface with the machine. What size is recommended. The Machine should be a CNC-Lathe in the end. Do you have some recommendations? Also maybe not topic related, but I was wondering if you can set up remora so you can drive the spindle with step/dir?

@NTULINUX. Note that I am not stranded in any way. I have a fully functional and production-ready RTAI kit (5.4.258, lcnc 2.9.2). Couldn't be happier about it and so kudos to the work that went into this!

You know what we're missing though? A tutorial on "How to compile a RTAI Kernel, module and Lcnc". Just so that workload could be offloaded off you, Bari, Andi, and friends. Personally I'd be willing to give that a trial with e.g. the newly released 2.9.3 or perhaps even 2.10.xxx as tests.

Prolly beyond most-of-us skills though, let us know what you think about this idea.

actually, this works in axis. its just qtdragon im having trouble with. thank you for all the help. as long as i have a working system, i can figure it out from here. thanks again.

Hi NTULINUX. I have no doubt in that statement, doubting my knowledge/skillset is in upgrading linux systems rather. Mind you I was able to use the 5.4.279 release full featured. Only bug was a new timeout error on starting, and ofc not being able to restart lcnc if closed - a full system reboot was required. 

To begin with I have no idea how to clean a previous RTAI installation (if required?), or whether it's okay to simply "upgrade over" which is what I've done.

Additionally (less inspiring!). I've completed a clean Debian 12 install on my newly acquired Dell Optiplex. All updated, all drivers functional, no errors, everything's happy. Then proceeded to installing the RTAI 5.4.279 debs (module, headers, image, then lcnc), to have nothing showing up when starting linuxcnc. It reports that module is not loaded, although re-installed the deb twice now

Not entirely sure what I've done to RTAI to deserve all that, we used to be good friends!!

Have you set the files permission to 'Allow executing file as program'?

Here is the part of the doc refering to custom M-codes:"The external program named M100 through M199 (no extension, a capital M, found in directory pointed by [DISPLAY] PROGRAM_PREFIX parameter of the INI file) is executed with the optional P and Q values as its two arguments."I followed this and the lcnc did not find the macro.

the txt must added to post to forum, but not used in lcnc.

Under the tab "NC Program Manager", select UTF-8 without BOM as your output encoding.
Hope this helps. 

I just pushed a fix for getting the LinuxCNC version so download and reinstall the deb.

Hi JT,
I just did a fresh install of linuxCNC 2.9.3 and MesaCT 2.1.4.

Things that I notice & happen-
When I run the software the info panel reports LinuxCNC version 2.9.0 not 2.9.3

1. I enter the machine name and check load this config & backup config.
2. When I press default Metric for the linear units, the info in 1. above disappears. In fact if I enter the Mesa setup, verify the board then press Default metric all that information disappears as well. Is this normal behavior for the software?

Also noticed step 3 in your help "Select Max Linear Velocity" does not exist on the Machine tab but it does on the Settings tab.


 

What does apt-cache policy linuxcnc-uspace in a terminal return?

Yes, the "default" buttons will create a new blank configuration and then populate some units and a few variables, mostly I used them for testing. Perhaps a different function would be better. If you have any ideas let me know.

Where are Lcnc M-codes are stored? 

I having hard time to run a custom macro in qtdragon_hd since the ini pah of subroutines not working. The macro itself is working. I also read and followed the docs on how to add multiple path to subroutines in the ini. 

So this is what I've discovered. And exactly what I expected to happen.

Using NFS
mount the nfs share via the mount command.
Tried this with both axis & qtdragon, using the file browser of each. Red is what I did on the linuxcnc machine, blue is what I did another remote machine. Server runs ubuntu, RPI5 is debian & Linuxcnc machine is running Mint.
Open a file in a sub dir of nfs share. create a file either locally on the server or via another pc (RPi5) that has the share mounted, go up one level, then back into the dir and I have no issues seeing the newly created files.
