Sherpa Mini - Dragon Burner toolhead sensor

Just a small filament sensor tophat for the great cutter from @demitrix_327464.  It can be used as a precise runout sensor or in my case as a toolhead sensor for the Happy Hare driven QuattroBox MMU (https://github.com/Batalhoti/QuattroBox)

BOM:

• 4mm steel ball

• ordinary microswitch D2F without a lever

• it adds few mm to the height of the toolhead, so maybe you will need longer screws, for me 35mm was enough

Print setting:

• use Voron print settings, and you will be fine

Install:

• connect the microswitch either in NO or NC setup, depending on your needs

• install the 4mm steel ball into the hole

• push the microswitch into its space in pressed state, it is snap fit, lock in place

• you can use screws to secure it, but it is really not needed, and be carefull to use right size screws 

• install it instead of the cutters top cover

• connect it to your printer board

• configure it in your printer settings as a filament sensor or in Happy Hare as a toolhead sensor

• you may loose few mm from your vertical height, so don't forget to modify your printer settings

Happy and more precise printing…

Just used the shape of the toolhead cutter to design a tophat for that.
