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.

      The goal of this contest is to design a set of people figurines that could be used in such a project to make an area, office or mall seem populated. 
      Think of different types of people in different environments, like walking people, people standing still, working people, and both men and women.

    • Taking Advantage of DfAM
      This is a statement that’s often made about AM/3DP. I'll focus on the way DfAM can take advantage of some of the unique capabilities that AM and 3DP have to offer. I personally think that the use of AM/3DP for light-weighting is one of it’s most exciting possibilities and one that could play a key part in the sustainability of design and manufacturing in the future.
