Is there an existing issue for this feature request?

I have searched the existing issues

If for example, I use 1mm seam gap (I know its too much) with 0.28 layer height it works well

But the same distance for 0.04 its not enough and causes overextrusion at the loop end

If distance is constant, the formula:

layer height x line width x distance

wont give the same result

Which printers will be beneficial to this feature?

All

Describe the solution you'd like

So if seam gap demands a certain volume... the distance will vary depending the layer height, making it longer for smaller layer height
Just like Cura coasting works

0.04

0.28

Both with 0.1 mm3 coasting volume (exagerated)

Describe alternatives you've considered
