New Trajectory Planner - Testers/programs wanted

The error occurs between N0330 and N0340 in the ngc file

I used your ini and my sim hal files (that have acc/vel calculated) and am not seeing any violation.

Couple of things.
-have you done a mem check?
-are you getting any realtime delays?
-could you have sticktion or something going on at that point to cause a following error?
-How is your tuning?

I could see the following error happening first - then the axis costing down creating the line as if it wasn't following the circle.

A few more things? What version of linuxcnc did you come from? was it 2.6? This would somewhat make sense that putting the trajectory planner ARC_BLEND_ENABLE to false puts it back to 2.6 - 1 segment look ahead. The new TP uses all your acceleration available compared to the previous (2.6 and older) TP which would use only half the available acceleration. (for blended moves) This would then point even more towards a tuning issue.

1. No I haven't done a memcheck
2. No realtime delays
3. I got the same problem with the motors mechanically disconnected
4. I think my tuning is good, have been running this tune for a year and this machine sees a lot of work
5. I came from JA9 which was based on 2.8, since my original post I reverted back but still get the same error. This leads me to believe linuxcnc just doesn't like that bit of gcode so I edited it and now seems ok.

Could you please elaborate on this

?

Does that mean you saw the same problem?

Cheers

which axis f-errrors? I assume it is Y? (joint 1 or 2?) it really hammers the acceleration around that point. (but doesn't violate it)
