Pressure advance test print

Test print for pressure advance (klipper firmware), but would probably be useful for Marlin's Linear Advance as well.

I add the command :

SET_PRESSURE_ADVANCE ADVANCE=0.100

At every 25 layers (5mm) and increse this value by 0.1, which gives me a range of 0.0 to 1.9

You can also scale the print down to test single pressure advance values.

Best printed with brim, because its very thin and you're not really testing bed adhesion with this print.
