First Layer Flow Ratio
Hello everybody,
I've been looking in Prusa but I can't find a way to adjust the first layer flow ratio. I see this option on the Orca slicer but not in the Prusa. Is there any way to do this in Prusa only for the first layer. The idea is to increase it to 1.08(ex)
Best regards

Not as an option no. Its in Orca Slicer as it was added to the Super Slicer fork as First Layer flow ratio and Orca has pulled in all sorts of code from various projects.
You could do it using some custom gcode though. In the Before/After Layer Change section. To manually set a higher flow on only the first layer using a conditional.

Adding in
M221 S{if layer_num > 0}100{else}120{endif} ; to the Before Layer change will set the flow rate to 120% for layer 0 (first layer) and 100% for layers after that.
At least for Marlin based printer firmware as M221 is Set Flowrate.

Thank you very much for your kindness. Would it be possible to tell which code to put in, I don't know how to do it!
RE: First Layer Flow Ratio
See my second reply, above yours. You need to be in expert mode in Prusa Slicer to see that section. Printer Settings >Custom Gcode> Before Layer Change field.
