Quickdraw mount for VZbot Alu Printhead.
Quickdraw 1 is the original older version. We have since updated to Quickdraw 2 and i would recommend everyone to use that.
Strip 2 24AWG wires for about 2cm twist the wire so no strands are loose and stick it in the back of the Quickdraw mount. Cut wires flush with magnets after they have been added into the mount and put a dot of glue on the wire where it enters the Quickdraw Mount. For added security you can add a tiny dot of solder onto the wire/magnet where they touch. be carefull not to heat the magnet since it will loose it's strength then.
The printed Printhead version is made for the backplate without tensioners. If you still tension your belts at the backplate this won't fit.

To use quickdraw a module needs to be added.
SSH into your Pi with a application like Putty and type:
cd ~/klipper/klippy/extras
wget https://raw.githubusercontent.com/cloakedcode/klipper/work-annex-probe/klippy/extras/dockable_probe.py
sudo service klipper restart
