Z Offset for better first layer control

[Mikk36]

I wonder if that would work with my PolyPro print bed. I only have the yellow carpenter's glue, but I could get some of the white and try it.

I don't see why it wouldn't work.
Some use a 1/10 mix with water, some pure PVA, I use a 1/3 mix. Just don't be surprised when your large print doesn't want to come off quite so easily, it sticks extremely well to larger prints. For smaller ones I give a tap from the side with a hammer, pops the items right off.
Just to clarify: I have a glass bed.

Would be nice to have an option like most slicers do where you can modify the first layer extrusion flowrate to be a % of the normal flowrate. That way you could do the Z-offset of -0.1mm and get the correct extrusion width.

Just use bed roughness (adn decrease Z offset accordingly).

Use the appropriate G-code areas in KISS to modify it only for the first layer.
