acceleration parameters

Recommended Posts

I wish to decrease acceleration, to see the effect on the ringing artefact.

Browsing through my UltiController Menu (on UMO), I see a parameter " Accel" on 3000, and a bit further down I see "Amax n" for n={x,y,z,e}. Values at 9000, 9000, 100, 10000.

What is the meaning of the first "Accel" parameter, which is set at 3000?

I believe the "Accel" parameter is the rate of acceleration used for X, Y, Z and E steppers when performing a move while printing. While "Amax n" limits the acceleration per stepper when performing a non-printing move.

Basically it uses the accel settings.

If I remember right, Amax is kind of a bug fix if Marlin miscalculates or panics and isn't supposed to be used. It should be higher than the default accel settings. I never quite understood that myself even after reading the code very carefully for many hours.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
