S-Curve/ sinusoidal , Jerk +acceleration

So much good discussion here: https://forum.duet3d.com/topic/4802/6th-order-jerk-controlled-motion-planning?_=1585069930938
I'm not sure why that thread was locked.

I think it just aged out. I can unlock it.

Why does that happen? Surely we should be encouraging users to search the forum for answers? If they find their issue is unresolved and they have more information to add why does it make sense default to fragmenting the conversation?

@DocTrucker in answer to your question about why old posts get locked, it's because Tony did a poll asking what user's thoughts on it were, and the concesus was yes, (
after 45 days IIRC). I'm not saying that's the right decision or otherwise - just explaining the process behind how it came about. -
@deckingman thanks. Missed that completely. Odd decision but fair enough...
-
@DocTrucker Yes I just found the poll - the result was a bit like Brexit - 53% for, 47% against. So not quite half are unhappy and slightly more than half are happy.

I think the main reason we wanted to do that was because when some users had a problem, they would resurrect an ancient thread that appeared to be related instead of starting a new thread.

What is so wrong about that? The information posed in those threads is not wrong just because it´s old.
It also makes it easier for future searches if tangent problems are all in a single thread rather than 50 separate ones. -
@NitroFreak the firmware was developing at a very rapid pace when that decision was made. Often, those ancient threads were no longer current. They had info which was outdated and applied in no way to current scenarios.
Now, we face that same rate of change so locking threads may become prudent (when they have outdated info).
-
Since that locking old threads decision we have also added a notice that shows the time elapsed since the last post to indicate more clearly when a thread has been resurrected.
Sometimes it's useful to be able to add information to old threads, and sometimes it would be better to just start a new thread. If you want to you can still link to the locked thread.
There's no solution that will solve everything and make everyone happy. It is what it is. If there is a thread you find that you want unlocked, message a moderator.
Anyway, none of this conversation has anything to do with S curve acceleration.
