Is it possible to set separate accelerations for the first layer, outer wall, inner wall, and infill of a belt printer? I only see options for setting speed.

on the belt, the `base` layer is any extrusion touching the belt. `finish speed` under `output` is any exposed extrusion. otherwise `print speed` is for interior extrusion. so that’s equivalent to inner and outer walls.

It seems that only the speed can be set here—can I set their acceleration individually?

meaning per layer? outer walls is `finish speed` and inner walls is `print speed` (default).

I mean acceleration setting，like this picture

I see. there is no UI for this at present. you would have to add a conditional IF/ELIF script in the `features` macro tab that injected the right klipper commands for matching features (which are print areas). yes, this is clunky and can be improved. but this project is just me in my spare time (for 14+ years) … so PRs and contributions are welcome to speed things along.

I see. I’ll give it a try. My programming skills are not that great—I can only write some Windows batch files.
