Virtue3 Nozzle Brush

I designed this arm to use the brush that came with my Cartographer probe. It can use any strip of silicone brush that is 35mm-36mm long and 8mm wide. I put 2 mounting holes on it that way it doesn't twist when being used. I didn't add any V grove pattern on the back of it as my extrusions didn't have V slot. 

I made a simple macro for the brushing that runs in a square. It is designed to run in a square and then perform the purge line on the build plate. The recommended spot on the Virtue3 is the front right corner. 

!!!!!---PLEASE CHECK MACRO COORDINATES BEFORE USING THE MACRO---!!!!!
