All parts can be printed in any material however it is recommended to print the flap out of ABS. The pellets may melt to the flap and become stuck if a lower tempature material is used.
The macros were created specifically for my printer so your settings/macros will be different
The included macros are designed to wipe horizontially so if you need to mount it to the side of the printer you'll need to edit the macros yourself
Make sure to edit the following values if you are using the included macros
[gcode_macro WIPE_NOZZLE]

# X location of the center of the wiper in respect to the nozzle
variable_wiperlocationx:
