What will you get?
A high-quality brass brush!
By modifying the slicing software script to drive the machine to brush over the cleaning brushes before printing.
Using VORONR2 as an example add the following code before the slice start script:
PRINT_START
G1 X250 F6000
G1 Y295 F6000
G1 E40 F500 ; draw prime line
G1 Z2 F2000
G1 X200 F3000
G1 X250
G1 X200
G1 X250
G1 X200
G1 X250
G1 Z10 F3000
G1 X155 Y155 F9000
Note: Different machines require you to modify the XYZ-axis limit position and Z-axis lift height during nozzle insertion.
