I needed a nozzle wipe brush for the JGAurora A5. It uses replaceable Bambu A1 silicone brushes which are pretty cheap and easy to get. Simply peel and stick. It goes into the bed frame on the left rear and the bed screw goes through the hole to further secure it. A small amount of play is normal to prevent hotend damage should anything go wrong.

I modified my printer to use a E3D hotend so my Y axis is about 10mm off. Having said that, this is what I pasted into my start gcode of OrcaSlicer after homing and auto bed leveling:

G0 Y300 ; Y position for scrub
G0 X60 ; X position for scrub
G0 Z1 ; lower to scrub Z height
G0 X20 F20000; scrub left
G0 X60 F20000; scrub right
G0 X20 F20000; scrub left
G0 X60 F20000; scrub right
G0 X20 F20000; scrub left
G0 X60 F20000; scrub right
G0 X250 F2000; scrub finished
G1 Y1.0 Z0.3 F1000 ; move print head

Please bear in mind your X, Y, & Z may vary so make sure to check each X, Y & Z position prior to using this, in particular the Z height. You may also make your own custom gcode to perform different scrubbing motions.
