Yeah the tipper module should be run at low speed for optimal throughput. 1 or 2 works the best with M and L motors, while XL motors can run at 3-5 on a train regulator.

 

The tipping bird module is brand new and trust me. If I made a video, you would chuckle at the failure of its current state.

Thank you for the recommendations for the tipper module and the clarification about the tipping bird.

Not GBC, but it has some interesting mechanisms which could provide inspiration:

Single Car GBC ball lift Mark 4                  

This was inspired by the successful build of The Sun GBC module.

Uses a constant rotating L motor drive which drives the turntable and the crank mechanism for the loading gate using a 32L axle. 

The L motor via right angle 1:1 &  3:1 speed up drives the worm gear meshing with the 20T double bevel gear which rotates the 32L axle.
The 32L axle has a 12TDBG to rotate the turntable & an 8T gear to drive the 40T gear with crank arm. Both are 5:1 ratio so allways in sync.
The turntable rotates a 13L beam connected to a 15L beam which raises & lowers the lift frame.

Lift frame is 22L travel which is max possible as axle cannot be any longer as any connectors would foul the lift frame.
The 32L axle passes through the back of the lift frame and helps guide the carriage.

The ball car carries 5 balls per trip which takes approx 8 seconds which giving a ball rate of 37.5 balls per min.
An anti jamming arrangment stops more than 5 balls entering the lift car.

The hardest part was getting the timing for ball loading correct.

Again the dreaded 1/2 L offset came into play but finally got it working.

Re-circulating ramps for video demonstration, but can be easily modified for through operatation.

Would it be better with some form of counter weight? You end up feeling sorry for the motor :)

Not possible as no room, any counterweight arm would foul the 15L beam connecting to the lift frame.
Clearence is only 1L when rotating arm is at 12:00 o'clock,

Load is light and motor is not straining - most of the noise is from the gearing.

Module is very free running and is reliable.

I uploaded photos about my module Orbit Overlap.

Notice that my module is not refined , and will not refined by myself.

If someone could improve my modules, I am very happy.

 

and I uploaded some new videos on youtube yesterday.

@Rick Katsumata I saw you posting them, but didn't post them here as I thought you might do so yourself.

I like the modular system.

Thanks for the photos of Orbit Overlap. I will get to work on a digital file for it.

What issues do you currently have with Orbit Overlap?
