How to build ATC Carousel in linuxcnc ?

Some reason I didnt get a notification of this reply. I just ended up wasting an axis on my carousel and making it servo. I'll probably never get around to making this a 5 axis machine anyway. If I do, Ill look into this component again. Thanks!

I have a major question. I see you are using a bt30 spindle and toolholders. I am looking to buy one myself, but how do you align the toolholder with the spindle so that the forks fit (aligning those notches ) and the tool can be fixed. I can't really find this googling. Is the spindle handling this itself by turning the toolholder till it fits or do you need to set them perfectly in the toolholder and the spindle orients always the same way or how is this working because my second way of thinking seems like a problem going to happen.

You can see that the spindle orients to put the tool in the correct orientation before each tool change.
There are a number of ways to do this. This one appears to be using the spindle motor and encoder feedback, but others might use a mechanical stop.

Thx, so it has to be placed in the correct position. Thanks that explains the next point of action.

It's called "orient" or spindle orient, it is included with linuxcnc and works with normal spindles just by adding a notch and a sensor.
Some VFD's have that implemented and they come with the spindle, so using that is a simple as sending an orient command and waiting for the spindle is oriented signal from the VFD.

I don't mean to hi-jack this thread. I am planning on building my own vertical ATC for my mill. Mine will be similar / close to the org. from the manufacturer. The mill has an extended X axis to reach the tool changer.

Picture from the manufacturer:

It's vertical 2 by X Tool Changer. So, for example 24 tools in total: tools 1 - 12 on the left side and tools 13 - 24 on the right.

Still trying to figure out what the best approach would be accomplish this type of tool changer.

Any feedback is welcome.
