Hello,

It's solved.
Git is updated.

@Evgen can replace or overwrite the tp_scurve.c from codeberg.
Then do a recompile for cmake : ./buid_cmake

The problem:
    In control.c Line 1867 it looks for 2 types :
    EMC_MOTION_TYPE_FEED
    EMC_MOTION_TYPE_ARC

Clothoid motion was giving no type.
Then the clothoid motion is now set to type EMC_MOTION_TYPE_FEED in the planner.

Now the motion.feed-value flippering is not there anymore.

What is using the hal pin : motion.feed-mm-per-second for example?

Set the servo period in the ini file to 2000000 (2 million) and set the P value for each joint/axis to 500.

So...

What if LinuxCNC complains while starting...?

When running the latency test Tommy suggested, I saw a similar graph.

I migrated my working configuration to the PI4.. Then, I was visited by the dreaded latency complaint.

Everything appears to work. I am running a Mesa ethernet card. What are the steps to debug and rectify the situation on a PI?

Frank.hal attached. Do you need to see any more files?

Hi,

When i run Posix non-realtime or Posix realtime scurve planner, i both get the same results as Evgen is telling us.

The hal pins that are flippering, blinking :

motion.feed-mm-per-second
motion.feed-mm-per-minute
motion.feed-inches-per-second
motion.feed-inches-per-minute
motion.feed-upm

I didn't look any further.

What is using the hal pin : motion.feed-mm-per-second for example?
I personally never used it, that's maybe i didn't noticed this behaviour.

@Pcw, link to gcode he posted before:

All the hardware seems to be detected OK and the error
is gladevcp related.

Does the parallel port configuration have this same error?
and if not, you might compare the hal files for lines involving gladevcp
