Z axis motors movement indicator

Movement indicator of the Z axis motors, also useful for checking any misalignments (which on my printer happens practically at every print)

For a better result I suggest to print it in two colors. For example if you use repetier server use these commands to change filament:

G91
G1 Z10
G90
G1 X0 Y200
@pausing
@pause
G91
G1 Z-10
G90
;end
