Brush Ender 3v2 Nozzle

https://youtu.be/pdU2WXR9dKI

Brush before printing, or between layers. Cura has a "wipe nozzle" setting for easy brushing between layers, no custom gcode required.

However you need to modify your Firmware:

1. Edit your X travel limit to 260

2. Home your printer

3. Manually trave as far as you can before running into the frame ( mine stops at 255)

4. Edit your firmware again to limit x travel to that value- 1mm safety margin



in Cura you can now wipe the nozzle, no Gcode required
