D-BOT Z Axis Synchronisation

Z Axis sync Belt set for the ever popular D-Bot

If you have 1 z axis which always seems to be a few mm out when you home after a print you need this!

Completely stops Z axis lead screws getting out of sync.

You must unplug 1 motor , weird and strange things will happen if you leave both motors plugged in.
