i just downloaded debian strech and its working flawlessly
i cloned linuxcnc-plasmac then cd to linuxcnc-plasmac/debian
and then ./configure -a (]it says no realtime kernals found)

also tried to booting it from grub boot screen but after boot it says same ( no realtime kernals found)


uname -a returns following

Linux debian 4.9.0-7-rt-amd64 #1 SMP PREEMPT RT Debian 4.9.110-3+deb9u2 (2018-08-13) x86_64 GNU/Linux


uname -r returns
4.9.0-7-rt-amd64


can anybody help with with this it says kernal is installed but configurre shows no realtime kernals found
i also installed linux cnc uspace
what i need to do in order to to solve this


thanks for your support guys specially rodv

did you run it from the environment script

If you have compiled run-in-place in will be in:

/path-to-some-directory-you-chose/linuxcnc/scripts

sir i booted it from grub boot screen ,,, it also shows uname right kernal name but not with uspace
its already integrated into iso i downloaded

Pleas Start Linuxcnc from the Menu

choos SIM Axis

then as you need QT to be setup for plasmac
Please Start
SIM
QTVCP
xyz

To setup the system Vars and parameters

You dident read the Documentation on how to get Started at all as it seams nothing is set in your system to run a CNC
PLEASE make a Screenshot WHEN the SIMMASHINE has started so we see you got qtpvcp running once then we know the system is set

lol you are always complining instead of giving solution ,,.....
i think i didnt make myself clear
my que is i have rt kernal do i need to install uspace ??
and why is it saying no rt kernals loaded

instead of boasting about ur knowledge and students and all
say yes or no
and do not confuse peoples if u didnt know what the question actually is

You should not need to go to the debian folder. I know some of the docs are a bit confusing here. Some of it is to build a deb file you can then install into the menus and stuff but I never bothered.

If you used the stretch ISO you have a real time OS (PREEMPT_RT) so no need to do any more.

On this thread, I included a dump from the terminal of the commands required
forum.linuxcnc.org/plasma-laser/36410-co...any-hardware?start=0

Make sure you are in the linuxcnc-plasmac/src directroy as shown here.
make sure you use the ./configure parameter I show you.

I know its hard but you need to follow one prophet. Don't mix the commands I mention with those that others mentioned.
The other thing is I did suggest people build the master branch from source before tackling plasmac as it will give you the confidence that everything is working and it will be easier for people to help you with the standard build.

its all there as you did install th DVD system
you just need to start it the correct way

sir .. i succesfully did it..... all credit goes to you but i cant see reverse ru n it is integrated in default axis
or i have to implement it using hal

sir linux cnc runs without . /script/rip-enviroment
if i try to set rip enviroment it says no such file or directory

Awesome work!. If you go through the sims in the chooser, you will see the plasmac sims. so run them up now and have a play. The reverse run feature is built into the Plasmac GUI so if you wanted to use it on another config, you'd need to look at how plasmac does it in hal.

Look carefully at the syntax for rip-environment. You need the extra full stop and a space...
