Description:
It appears that the exact jerk/motion issue previously fixed under #3773 has reappeared in the current 2.10 development branch (as of September 2026). I haven't tested 2.10 for quite some time (not since March 2026), so I cannot pinpoint exactly when the regression was introduced.
Even with PLANNER_TYPE = 0, using the exact same G-code that was used to track down the original bug triggers the exact same symptoms.
Steps to reproduce:
Load the attached/original G-code from issue #3773.
Run the program using the current master branch.
Observe the identical motion/jerk symptoms as described in #3773.
Additional context:
LinuxCNC version: 2.10 (Current master)
Planner type: 0
