When I try to print the 3D Benchy model with an acceleration of 20,000 mm/s², a speed of 1,000 mm/s, and the Minimum Cruise Ratio turned off, an error occurs: MCU “EBB” shutdown: Timer too close. This error is reproducible.

Hello @NGYX !

Don’t yo think those values are a bit high?

@EddyMI3D, jfyi, it is totally fine, I assure you. Physics does not restrict that.
I can also do that :smiley:

You can either do:

  • Ask Kalico crew
  • Use the latest clean Klipper

Hope that helps.

No way, I used AWD. This speed shouldn’t be considered fast.

AWD has nothing to do with mm/s - voltage does
AWD has to do with acceleration, so mm/s^2

Anyway, this is true, that generally the above numbers are not insane.

Sorry, my translation software mixed things up.

Thanks, I think I should go to the kalico branch to ask instead.
