I am trying to print with clay.

These are my Slic3r speed settings,

Slic3r speed settings

Other information;

  • Nozzle: 1.4 mm
  • First layer height: 0.9 mm
  • layer height: 1 mm
  • Filament dia: 1.8 mm
  • perimeter: 3

When I print, the first layer is printed faster than remaining layers and in the remaining layers, the two inner perimeters are printed much slower than the outer perimeter.

Isn't this strange since I give the same print speed for all?

No, you did not set all the settings to the same speed, there are 2 different print speeds defined:

  • Infill Solid: 60 mm/s
  • First Layer Speed: 30%

This means, that some walls will be printed 10 mm/s faster than the others, and that first layer should be printed at 30% of 50 mm/s, so at 15 mm/s - try to define it as a speed. Make sure to save and apply the settings and only then slice your model, as you might have sliced the model with the previous settings.

Make sure that on the Print Settings tab, under Advanced, you have set the Extrusion widths for your custom nozzle settings.
