Coordinated Motion involving rotary axis

I believe that with the old trajectory planner the naive cam detection is the difference between G64 moves in only XYZ and moves with ABCUVW. If I turn of the naive cam detector (Q0) then the XYZ plot looks the same as moves with ABCUVW.

I think there is a small bug in the new trajectory planner when the naive cam detection is turned off (Q0). Notice how at the end of the move there is a strange blip in the velocity. That blip is not found in the plots I made using 2.6. I also think I've seen it on some plots on other threads where people where having problems with G33 and G33.1.
I'm not familiar with the processes for reporting bugs, are there instructions somewhere?

A good way to make a report and not have it lost in
transient conversations is to open a ticket on
sourceforge (you probably need to create a sourceforge
login).

sourceforge.net/p/emc/bugs/?source=navbar

The more information you include, the more likely a
report will be investigated.

For instance, include:
1. system and linuxcnc version info
You can use the output of the command linuxcnc_info 2. sim configuration (a complete tar file if necessary)
2. example gcode file to demonstrate the issue
3. halscope configuration (use halscope File/Save Configuration
to create a halscope config file)
4. detailed instructions to demonstrate behavior
