The brush holder is mounted on the hotbed connector, allowing you to easily move or remove the build plate. You don’t have to worry about the glued silicone wiper when changin plate. The design also takes only a very small space on the build plate. Mount with one or two M3x16 screws. One M3x16 screw comes with the printer to mount the accelerometer and it is enough. 

Print with 0.1 mm-0.2 mm layer height, use default grid supports. Other settings don't matter much.

The wipe macro

disclaimer: I am not responsible for any damage that is caused by this macro but I've tested it a couple of times and it hasn't failed or crashed

First you need to modify your printer.cfg. Change the value of [stepper_y] position_max to 228 so that the bed can move to the wiper. Also change the [safe_z_home] z_hop to 10 to avoid crashing into the wiper. 

Then change the attached Wipe_Nozzle.txt macro file's file extension to .cfg and copy it into your printers config. Modify your printer.cfg again and add "[include Wipe_Nozzle.cfg]" to the beginning of the config file.

Finally add the macro into your machine start/print start gcode in your slicer by putting "Wipe_Nozzle" after the purge line and before the M400 command if you have that.

Now you should have a working nozzle wipe macro. Test it first with your finger on the emergency stop button. Also make sure to clean the upper part of the nozzle frequently because filament can pool up there.
