UTZrack V2 - Dual drive - larger servo - Tradrack alternative

Tradrack MMU Modified as required to suit my needs.

Now has dual drive gates, and larger servo with larger servo horn.

Note: Gates are larger, you will either need to extend the belt, linear rail and 2020 extrusion, or use less gates.

Works flawlessly now with these mods so thought I would share.

Mods listed below.

Mount for BTT encoder instead of Binky (Could never get binky to work accurately , BTT encoder works flawlessly)

Modified infeeds with brake and dual drive - brake uses 8x3mm magnets

You will also need the following additional parts per gate (refer links and images)

M3, 18mm cylindrical dowel pin x 1

Can use either std gate stop microswitch or switch installed in BTT encoder (set gate_parking_distance: 45) if using encoder switch  and encoder distance to 0)

Bottom cable guide bracket extended to match the encoder bracket

Additional end guide required so last brake doesn't come out of the infeed during use.

Infeed modified to use PC4-M6 bowden holders (My ECAS fittings kept popping out when retracting)

Left hand End Bracket extended as required when adding brake
