-Use "carousel" component as is

 

That's the current problem.

The new 'counts' mode seems to be working...ish.  At slow speeds it's reliable, but starts acting up if the speed is increased - at least for me.

And you don't need a pocket sensor.  Carousel component keeps track of position once it's homed to a single index sensor.

You could probably 3D print tool forks but I'd like to see a bunch of testing before I trusted them over injection moded forks.  Same thing goes for mechanical bits with weight on them.  I'd be concerned about cold creep over time.

Ooops
You are right, it does not need one.
As to the rest of your reply, i am fully aware of the drawbacks, but if it can be 3D printed and usable for a while, just print more and keep changing!
I am sure there might be a way of doing a partially 3D printed changer that will last, but printers are cheap so we can use them for this, and we like to tinker.
Then again there is the rack tool changer, easy, simple, no remaps, works properly, lasts a lot, BUT takes a good portion of the usable working area.

I'll go out now and have a smoke and feel ashamed that i missed the reality of carousel with stepper = no need for pocket sensor.
My dog will be happy to see me, it is 2:30AM here so he is awake, sleeps most of the day.

While you're feeling ashamed, can you figure out why the carousel acts up at higher speeds?

And give your dog a pet for me.

Using steper or step/dir servo ?

Closed loop stepper, no feedback to LCNC.

It's not losing steps, and carousel.comp doesn't lose track of position.  Works fine at speed '25' (whatever that means), but if I turn it up past that it starts making whole extra turns before settling on the right pocket.  i.e. instead of one increment moving from pocket #1 to #18 it will rotate 3 complete revolutions plus one increment.

And the faster I set the speed, the more extra revolutions.  Happens in both directions.

BTW, I think the speed is probably based on stepper counts per rev and not time-based, but I'm not sure.  I just know that "25" is slow - like 1.5-2 seconds per pocket.

Can you do a video?
Preferably on youtube.
