Speed issue with Slic3r and Marlin I am trying to print with clay.

These are my 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.


Video: print video
G-code: gcode


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.
