I would love to see the (Extrusion Multiplier) available on the first layer settings like below:
So.....to increase the amount of plastic being extruded relative to the layer height on the first layer....ie increase the extrusion multiplier....simply reduce the layer thickness below 100%.First Layer Settings (These are applied to where the Bed touches your model. If you have a raft, that means the First Layer Settings will apply to your raft).
First Layer Height: This % will take a % of your Primary Layer Height. If you are printing with a small Primary Layer Height like .1 mm I would recommend a First Layer Height of 250%, to get about a resulting .25 mm first layer height
If your First Layer Height is below 100%, the extrusion amount will remain the same, only the Z-will change, but if you increase above 100%, the extrusion amount will scale accordingly.
First Layer Width: the extrusion width of your first layer, you may find that your first layer sticks better with a thicker extrusion (100%+). I don't have too much experience with this, but I think 125% or 150% would be good starting points.
First Layer Speed: Slows down the First Layer Speed to a percentage of your Default Printing Speed (Other tab)
First Layer Width means in no way what you think it does. A 50% reduction in first layer width will result in 2 times the frequency of extrusions, not a 50% reduction in extrusion width as you have suggested.dkightley wrote: ↑Fri Jan 06, 2017 5:05 am

Personally, I adjust layer thickness and global-z position in combination to achieve exactly the same result....which I'm perfectly happy with. I would prefer to see development time being used to make changes that can't be done any other way (other than using a different slicer) - like sorting out thin wall behaviour!
Just a note:
Thank you for refining my solution.parallyze wrote: ↑Sat May 28, 2022 9:58 amJust a note:
Check if your printer does support M221 and what parameters it's using before adding this.
This is dependent on the firmware running on the machine, older ones like Sailfish don't
understand M221, others (RRF) might require a "Dxx" instead of "Txx".
