Hmm, the override issue is odd. I'll have to double check my changes, because I designed it to account for that. It should work if you reduce the feedrate < 100%, but I still need to implement a check to allow feedrate overrides over 100%. Did you try overrides lower than 100% too?
That initial "cut" that your image shows definitely shouldn't happen. The very first blend is not made into an arc because of the way I wrote the optimizer, but it should definitely not jump ahead by 20 moves or so. I think this might be due to the blend not handling "overshoot" correctly. Currently, the final position isn't exactly reached, so I push any overshoot from tcRunCycle onto the next move. If the overshoot is higher than the entire next move, this may cause trouble. A hack fix to this may be to limit the velocity of short segments. Can you rerun that test a few times, making sure that overrides and such are set to default values? I'll do the same with your config and my own slow-speed config to see if it's related to the machine limits. Thanks for running these trials!
