Hello,
I'm getting some weird behavior, as I increase speed and acceleration arc moves become slower, I can counteract this by increasing jerk, however doing that angular moves e.g a 90 degree move becomes garbage.
Just as an example of what I am experiencing printing a circle 4mm at 30mm/s a complete circle takes the printer lets say 1 second to complete (fluid motion), when I increase print speed to 60mm/s same 4mm circle takes 2 second to complete, and 4 seconds at 120mm/s, and now printer does hundreds of start/stops (stuttering). (numbers are not accurate by any means but given as example)
I have not observed this behavior from simple angular moves where printer only has a few commands change direction.
