This is a temporary space to hold experimental front assembly with shutter for Open Trickler.

Be aware - it is not yet supported by OpenTrickler firmware.

Shutter operation requires two 9g servos (e.g. MG90).
One of the servos needs to be reversed in order for two servos to operate from common PWM signal.

Parts list:
-2x mg90 servos and screws that come with them (2x servo mouning screws + 1x horm mounting screw)
-4x m3 10mm screws to attach servo mounts
-4x m3 inserts for the assembly as per Open Trickler project
-1x universal servo reverser (4-6v) or servo revers moddification <link> https://www.aliexpress.com/item/1005005334996182.html?spm=a2g0o.productlist.main.1.34d97ea2vN4uLf&algo_pvid=ec48d0f8-7748-4ebb-99c8-f0d147cfabc8&algo_exp_id=ec48d0f8-7748-4ebb-99c8-f0d147cfabc8-0&pdp_npi=4%40dis%21PLN%218.76%218.76%21%21%2115.56%2115.55%21%402103893b17120051183643452e9bdf%2112000032651066104%21sea%21PL%21128038240%21&curPageLogUid=9MOoOg8vEuu7&utparam-url=scene%3Asearch%7Cquery_from%3A <\link>

If you decide to do the servo reverse mod, please refer to below giode.
http://www.rccrawler.com/forum/electronics/53956-step-step-servo-reversing.html

In short:
0.Move servo to an end possition (does not matter which end
1.Unscrew & take motor and potentiometer out
2.Move gears to the opposite end possition
3.Switch motor polarity
4.Switch side pins of servo position potentiometer, leave middle one connected
5.Re-assemble

Servo movement:
It takes 102 degrees of movement to fully move from open to close.
It's safest to use middle servo range angles e.g. 30-132 in a 0-180 servo.
This will help mitigate servo endpoint quality issues or misscalibration douring servo reversal process.

Suggested sequence of assenbly:
-Maunt servos with installed gears to front assembly
-Initiate Servo open position
-install shutter gate in open position
-screw assembly to plate and the slide
