Is anybody use “acceleration control” in Slic3r settings? I think this may significantly speedup the printing of large details, or am i wrong?
Acceleration control just overrides what you have set in your firmware. It allows you to have massive acceleration for things like infill where wibbly-wobbly-stringy-wingy bits of plastic aren’t going to be seen. And lower acceleration for things like perimeters where detail matters.
I’ve been curious about this as well.
@ThantiK We can set all this parameters in “Speed for print moves” section, so if you are right the “Acceleration control” section does not have a sense. Also i must notice that acceleration section measured exactly as acceleration (mm/s²). So i think we can adjust how the movement will be accelerated and then slowing down during travel from beginning to the end of the line.
Speed is NOT the same as acceleration. The acceleration controls how quickly you go from 0mm/s up to your target speed.
So, anybody use those parameters?
I do, experimentally.
I did, but had to drastically reduce my acceleration setting for i was getting resonance issues.
The way i see it is this: If you’re limiting acceleration because you’re using a wobbly or heavy bot like the Printrbot or a v2 Prusa, where high acceleration would cause edge overshoot artifacts, then using a high acceleration value for infill and a lower one for perimeters can improve both speed and quality. If, however, you have a rigid or light bot, like a Prusa v3 / Mendel90 or Ultimaker, and are limited by the motor’s torque, then you can (and should) always use maximum acceleration as long as your hotend can keep up. Slow acceleration can lead to plastic bunching up along the edges of solid infill areas.
