[Feature] Change layer in infill zone or in inner perimeter for super clean seam

[mimorational]

Cant believe I'm first to think of it, but havent found anything in discussion

If layer change will be happening not on outside surface, this will obliterate the need to calibrate the seam settings because all the mess will be hidden. Can be placed both on infill zone or inner perimeter I suppose

This should result in very thin and clean line seam

You could try out if this works by yourself. Simply slice a cylinder normally with 1 bottom shell layer and grid infill, and then edit the gcode file:

1. Delete everything after the second layer
2. Add a small G1 move at the start and the end of the second layer, as described in your picture.
3. Duplicate the second layer 100 times, adjusting the Z height for each layer (or using G91/G90 to move up relatively)
4. Print it
5. Look at the seam and see if you like it better.
