As mentioned by @LifeOfBrian the initial error is a “Timer too close”. The rest of the errors are IMHO purely consequential to this and should be disregarded.
Hard to tell if this is related to using arcs or not.
Generally, I do not see any valid reason to use arcs with Klipper:
- A 3D printer is not able to move in a circular motion → An arc always needs to be broken down in discrete steps as movements of X and Y
- This is nice for firmwares that suffer from bottlenecked serial connection bandwidth → Klipper does not
- The arcs IMO come out of a time where CNC have been programmed by hand and today and especially with 3D printers I personally see no real use
- On the contrary, it might even introduce yet another approximation step
