scurve trajectory planner

Hi,

I wonder if you accidentally changed it somehow globally.
I am quite sure i didn't changed code to the interpreter itself. What i use is a recent lcnc clone.
Then the current G64 Q[x] interpreter behaviour is not ok. It's also showing the same at mr. Hmnijp pictures at page 3.
Maybe a dev can take a look if they have time.

Yes better not blend G0's.










 

HI at all.

I have test installation on Debian 10 :

git clone --recurse-submodules codeberg.org/skynet/linuxcnc_scurve_compact lcnc
cd lcnc/cmake
./installer

It not istalled with success, some error in terminal :

Compiling libnml/posemath/posemath.cc
c++: error: unrecognized command line option ‘-std=gnu++20’; did you mean ‘-std=gnu++2a’?
c++: error: unrecognized command line option ‘-std=gnu++20’; did you mean ‘-std=gnu++2a’?

and:

/usr/include/ceres/jet.h:165:10: fatal error: Eigen/Core: File o directory non esistente

^~~~~~~~~~~~





eccc..

I have test installation on Debian 10 :

Master branch no longer supports debian 10. You will need to try this on debian bookworm or maybe manually change the makefile entries to 'std=gnu++2a'

Hi . i have delete std=gnu++2a'.

but have again anothers error.

too bad it would have been nice to be able to use scurve on debian 10 installations

 

Hi i have install Debian 12 uspace , with linuxcnc 2.9.4 , image the linuxcnc.org.

I have executed :
git clone --recurse-submodules codeberg.org/skynet/linuxcnc_scurve_compact lcnc
cd lcnc/cmake
./installer

have error in terminal:
/usr/include/ceres/internal/fixed_array.h:33:10: fatal error: Eigen/Core: No such file or directory
33 | #include <Eigen/Core> // For Eigen::aligned_allocator

and


/usr/include/ceres/internal/fixed_array.h:33:10: fatal error: Eigen/Core: No such file or directory
33 | #include <Eigen/Core> // For Eigen::aligned_allocator

If add in tray the file ini :
TPMOD = tpmod_scurve

and start sim/axis_9axis_mm.ini have error :
