Thank you so much for the independent testing, really appreciate it.
On another note, for who is not following the PR posts, Andy Pugh and the other devs decided to merge as soon as they can into master branch, so that it can get more wide testing, and probably be part of the 2.10 release, also I will leave here the same thing I posted in the PR on GitHub:

By the way there is also a PLANNER_TYPE = 2 which I have not documented at all, I intended to remove it, but have not come around to do the cleaning yet, that could be cleaned, or the community could be doing some further testing.

The main practical difference is in how they handle cornering velocities during blends, type 1 is more cautious, while type 2 balances smoothness with speed, in my testing type 1 wins out in most scenarios.

A couple of us played briefly today on Trixie and we built some debs to share with a few friends.
In the sim, I would like to see 
HOME_SEQUENCE=1 for all joints 
This will enable the home all button to save some time when playing. No need to home each joint.

I'm just having trouble with a corrupt APT system on my Linuxcnc PC and I am getting latency errors on my  office PC so I could not see much but I did briefly see some nice curved graphs in halscope.

I think if it was committed, there would be a stream of testers to find any remaining bugs...

I saw it the first time I opened it. Couldn't bother myself to fix the sequence on a Sunday afternoon lol
I will fix it for y'all tonight.

Edit:
Done, pushed to github, the ini configuration is better suited for quick testing, you don't even need to home it ([TASK] NO_FORCE_HOMING = 1), but if you do is just one click, and you got infinite limits to load your wildest g-codes.
