There must be an issue with pathing differences between package installs and run in place installs...

Try this as a workaround from a terminal:
mkdir -p ~/linuxcnc/nc_files/m_files
cp ~/usr/share/doc/linuxcnc/examples/nc_files/plasmac/m_files/* ~/linuxcnc/nc_files/m_files/
Then restart linuxcnc again.

Hi Phil,

I get this :

plasma@plasma:~$ mkdir -p ~/linuxcnc/nc_files/m_files
plasma@plasma:~$ cp ~/usr/share/doc/linuxcnc/examples/nc_files/plasmac/m_files/* ~/linuxcnc/nc_files/m_files/
cp: cannot stat '/home/plasma/usr/share/doc/linuxcnc/examples/nc_files/plasmac/m_files/*': No such file or directory

This is out of my territory I am afraid :(

My bad...

Need to remove the ~ from the beginning of the second line:
cp /usr/share/doc/linuxcnc/examples/nc_files/plasmac/m_files/* ~/linuxcnc/nc_files/m_files/

No success Phil, I still get the M190 related error, see screenshot attached. I must admit I have never used sim configurations, so this is out of my depth :(

No worries, this is distracting us from your main issue anyway. 
I really don’t know what is going on with the velocity as it works fine here. I will have a play in the morning and see if anything odd happens.

Thank you Phil, I will have a deeper look here too.

I have attached a short video made with PEEK which shows the velocity increase at the last leg of the contour. Maybe this gives a bit more insight in the issue we're facing.

Cheers, Peter

Could you open halmeter from a terminal and select the pin plasmac.feed-reduction and then do another video. It should change to 60 as it begins each fillet end return to 0 at the end of each fillet.

Hi Phil,

I had a chance to make up a video with HAL Meter and the feed reduction stays at 60% except for the last leg.

Cheers, Peter

The feed-reduction pin should be directly connected to motion.analog-out-03 which should be switched by the M67 E3 Qn g-code commands.

Could you look at motion.analog-out-03 with HAL Meter and see what it does.

They do change state correctly here.
