Yes and thanks Joco for your testing.

Something is missing indeed. But i think cmake is complete. It's problably in the lcnc python scripts.

If you copy the all the python scripts from the src dir into the bin dir,
this may solve the lcnc startup problem.
I think one of the src python scripts has to be in the bin dir.

But i can't reproduce this startup issue at my pc, here it's starting lcnc.

The compile side the of the build script in the cmake directory probably is done the rest is not. That was my point but I was not specific enough. The more correct remark would be that the script build_all is missing things. I make this comment on the basis that running build_all should compile and successfully run axis with the new module. If it is not achieving that it is missing either setting correct paths or copying needed files to the appropriate locations or whatever the root cause is.

But i can't reproduce this startup issue at my pc, here it's starting lcnc.

 

My suggestion is you spin up a virtual machine (VM). I use vmware player for all my lcnc dev instances, mainly because it supports the VTK plot correctly. Whenever I get an issue that I can't reproduce I spin up a clean VM to check from. That way I know it is not polluted by anything I have done before. Only when I have things behaving in the VM do I move to physical kit connected to hardware.

I will do some digging myself but in honesty it feels like I am taking pot shots in the dark hoping I get lucky. :-)

Hi All,

I just finished another scurve motion planner. tpmod_scurve_skynet.so

Features :
  1. Look ahead at runtime.
  2. Path rules.
  3. Motion forward, reverse.
  4. Jogging while pause.  (joke image missing /media/kunena/emoticons/laughing.png)

Video :


Github is updated with this new planner.
We have to add another few path rules, like tiny arc's that are colineair etc.
But for now i am happy with the result.

@ Joco,
Good idea to use a vm for resolving the startup issue.

Sooo impressed with what is being done here!  I am trying to get a test machine set up to actually try this on real hardware. I had a build fail last night but that could’ve been just getting a cut of the code when it was in flux. At least that is how it feels given I have had a successful build in the past. 

I am very keen to see what difference it can make on my current plasma table. Especially how far beyond my current 1000mm/s/s acceleration limits i can push before jerk/wobble issues return.  

cheers - J.

Hi Joco,

Sooo impressed with what is being done here!
Thank you very much !
It's not easy. image missing /media/kunena/emoticons/cool.png

Ok that would be nice !
I hope you can see the scurve magic on real hardware soon.

Did another test with a plasma file. Not 100% ok, but good for now.

Build failing again. Can't build linuxcnc using normal make or cmake.

have you done any changes to break the standard /src build? i.e. does it work for you?

I have just spun up a net clean Debian12 VM, cloned the repo, covered all the dependencies and no joy per above.

Not sure what the issue really is.  Appears to be trying to use a directory or open a file in a place it can't?
Warning: Spoiler!


The cmake issue is truely odd.  The same gtk issue as before but the libgtk-3-dev is installed!
