It serves two purposes:
Lowering to the end chain link which relieves some of the stress off the loom
Moves the loom back to avoid hitting the gantry

This was designed for my Balco v2.1.

Any comments will be appreciated.

1. Please lightly file the bottom of the printed chain link, it doesn't always print perfect.
2. It is possible to mount this using the supplied tapered M3 bolts, but I recommend at least m3 x 10mm bolts.
