IMHO
Lack of documentation of linuxcnc's core is probably the main reason it doesn't get developed much. few people have the skill and time to get up to speed.
Only a few people have experience with the core.
The only reason we got a look ahead planner is because Tormach paid someone to do it.
I agree help from Academia would be welcome - detailed documentation would be the first step.

I ventured into the source looking for something recently (and went round in circles) and I reviewed the current developer docs today after reading your post Chris. I think what's missing is an overview of the source code files. I know there is some block diagrams in the docs but they are not cross-referenced to the code. Unfortunately, its not really a task a newbie could do.

Yes I remember doing the same thing for the first year or so.
That would be a good little project...hmmm

dear all,
are there specialists in core trajectory planning algorithms of LinuxCNC willing to contribute to a better documentation, allowing Academia to use LinuxCNC as a platform for developing, testing, and integrating new algorithms in LinuxCNC ?
I offer my help for proofreading and improving the doc.
I'm newbie in LinuxCNC, but from Academia, and working for >5 years in the field of optimal trajectory generation.
Let me please know if you find volunteers,
Raoul

The current expert is probably Robert Ellenberg, as he re-wrote the trajectory planner a few years ago. And he seems fairly deeply embedded in academia.

Might want to look at..
forum.linuxcnc.org/38-general-linuxcnc-q...oth-velocity-profile
It is a start and the first one that I have tested that shows promise.. he is on irc.

That would be awesome, im not a coding expert but if there is something that I could do please don't hesitate.
Best Regards

Is there a library overview for LinuxCNC? I am interested in getting a good handle on this source and happy to help with enhancing the documentation along the way. I might try to use something like Doxygen to help annotate/visualize the codebase.
Obviously an enormous amount of work has gone into this and we newbies are extremely grateful to those of you who have created and sustained this project!

Robert Ellenberg is not so active anymore last years. His github channel is stil alive. I merged his code, so i know what he is capable too. Robert is an expert.
For linuxcnc the main folder structure picture is missing. So new academic users, don't know where too find someting.
I prefer to make some thing like the attachment too make things easer to find instead of wasting time on porn.

I am going to try to sit down over the next month and try my hand at documenting some of the source. I'm doing an LCNC router conversion so I will have some extra motivation.
I'll start off with some kind of an organized approach on Github (unless there is a better, non-MSFT option) and once I have something there I'll check back in on this thread with an update.
Are there any individuals on the forum, or threads I should look to to try to get deeper insight into the codebase?
