LinuxCNC S-Curve Accelerations

Hello, brother. I've found the official S-curve code, which is based on discrete-time mode, but I feel there might be an issue.You can try to implement Dynamic S-curve velocity trajectory profiling.

Hi Barney,

Thank you for your contribution. I was not aware of this code.

The "linuxcnc_micges_scurve_test2" branch has addressed errors caused by iterations, and I have extracted and plot the results using MATLAB.

Hi Barney,

Interesting results.
Did you did a git clone and then a git checkout? I got errors with tlc versions when try to ./configure this version.

Coming time i will try to dive some deeper into the linuxcnc source code.

Anyway. Can you try this scurve jogging repository to show a result in matlab?
github.com/grotius-cnc/linuxcnc
It has a build script in the cmake dir and starts the axis gui after install.




 

Hi Grotius,

Yes, I used git clone for building.
I encountered the following error while building and how to fix it. 

You can also try building with MATLAB.

Hi Grotius

Linux kernel version should not be too high.
I'm using version 4.19

官网分支中好像还有个使用 贝塞尔实现的方案。
