Carousel - dont work w/o trigger was created by zz912
Hello,
We have Brother Tc-211.
I has rotary ATC.
I use HAL component carousel.
Binary encoder 4 bit, w/o trigger bit.
Controlled by asynchronous motor.
Pin for controller - carousel.0.motor-fwd and carousel.0.motor-rev
My problem is that the encoder doesn't have a trigger bit, so sometimes some bits are read faster than others. The carousel component is confused by this.
So we have a problem when moving from position 9 to 8 and from position 3 to 2.
Why is this so:
9 = 2^3+0+0+2^0
8 = 2^3+0+0+0
3 = 0+0+2^1+2^0
2 = 0+0+2^1+0
When I want the revolver, let it turn from position 9 to 8 or from position 3 to 2. Then the engine starts and immediately stops. A situation occurs when, due to manufacturing tolerances, bit ^0 (2^0=1) turns on one millisecond before the rest of the bit, and the program thinks it is already in the position where it should be (but physically it is not) and turns off the rotation relay.
Any Idea what should I do now?

It did not help:
I am in position 3 and I want move to position 2.
ATC descends from position 3 and stops.
ATC generally works, but some positions do nonsense.
