A large coaster that can also be used as four small coasters.
For a two-color result, the filament must be changed during printing.
The base plate has a height of 2mm, then followed by the decoration with a height of 0.5mm.
With a layer thickness of 0.25mm, the filament change must take place immediately before layer 9.
I have modified the GCode in the corresponding line and inserted the following commands there.
;LAYER:8 G0 X50.3 Y74.044 Z2.25 ; first command for layer 9 G0 F3150 X50 Y10 ; move to filament change position @pause ; switch Repetier-Server to pause-mode M104 S210 ; switch-on hotend after pause G28 ; home all axis G1 F150 Z2.25 ; first only lift vertically G0 F1000 X50.3 Y74.044 Z2.25 ; move to first position in layer
