Specifying 1st Layer Extrusion Width

[inventabuild]

To make sure my print sticks to the bed it is recommended by the manufacturer of my printer that the first layer extrusion width be 125% of the extrusion width. Please let me know how to specify increasing only the first layer extrusion width and then defaulting to the extrusion width for all subsequent layers.

maybe offset Z in the printer options -25%? so the first layer height would be shorter and mush the filament into the bed. (I'm guessing it might work. I don't know)

125% extrusion would definitely blob up more plastic on infills on first layer. I'd rather suggest better Z calibration (slightly closer) to get the same effect.

Thanks for the suggestions.

What I do is to set the Bed Roughness to 0.03 and the Z-Offset to -0.03.

Usually I print between 0.15 and 0.25 mm layers so this mean 12-20% more extrusion on the first layer.

It works for me very well.

Sometimes manufacturers say bullshit
