Snapmaker 2.0 nozzle cleaner

A simple nozzle cleaning attachment that sits attached below the print bed assembly. Can be used before printing or on nozzle changes. Has little buckets to either side to pick up little bits of crud that falls off.

This requires buying a 20mm/3/4in brass dremel attachment to act as the brush bristles. I wouldn't recommend steel or harder metals, since this would be too abraisive. You should also probably use steel nozzles since this may wear down brass nozzles.

My start gcode is as follows:

;— Start G-code Begin —
M104 S{material_print_temperature_layer_0} ;Set Hotend Temperature
M140 S{material_bed_temperature_layer_0} ;Set Bed Temperature
M109 S{material_print_temperature_layer_0} ;Wait for Hotend Temperature
M190 S{material_bed_temperature_layer_0} ;Wait for Bed Temperature
