bed mounted nozzle wiper for the cr6

made a nozzle wiper that fits on the bed of the cr6 which uses an a1 style silicone brush

before installing make sure the printed part doesnt go into the z extrusion

to use this wiper you need to change your max x position to between 250-255(255 is max before a bolt hits the z axis plate)

the z height is tuned for my specific setup of a revo hotend, i have no idea if its a suitable height for the stock hotend or anything other than the revo, so make sure that your nozzle doesnt go into the printed part when using the macro

before gluing the brush into the part make sure it fits without buckling, as the aliexpress version i bought were a bit too long i had to trim them.

only 2 things you need for this wiper are:

2  m3 nuts

1  a1 style silicone brush(aliexpress is much cheaper than bambulab and is the same quality)

 G1 Z{fixed_z + lift_after} F1500           ; Raise the nozzle by 50 mm

print in either abs(better) or petg(printed in 100% infill because 80c bed temps pull the nuts through holes and makes it loose, 100% infill fixed this for me but i dont know how long it will last)
