Thanks for helping debug this, the changes are now in 2.8 and master.

I have a locking pin on my carousel. Which is normally in the locked position. What do you think is the best solution for getting the locking pin to work with the jog function?
1: Change the function so that the lock pin is normally in the open position and change in the G code sequence for the tool change.
2: Do a G code sequence that opens the locking pin and looks at the inductive sensors stauses and then sends signal to the carousel to start. When the jog button is activated. (Would be nice to be able to hold the jog button to be able to jog multiple tool holders at once)
3: Other solution.

I think that you can operate the locking pin using an inverted version of the "active" pin. Either invert it in HAL with a "not" and pass it to the output pin that controls the lock, or simply pass it unmodified and invert the sense of the output pin.

I am trying to make my ATC for a lathe, from what I have read it can be controlled in three ways: by G code, using the Carousel function and by CL, but the truth is that I have not found any technical information regarding how to implement it, especially how to implement the sensors to control the position of each tool. I have not found any electronic diagram, only information on the modification of existing ATC. How could you help me about it? I am using version 2.9, is the Carousel function available for this version?

How do you _want_ to implement the sensors?
If you can, I would suggest a gray-code + strobe setup. ie 4 sensors for an 8 station turret, 5 for a 16 etc.
For a lathe it should be possible to configure carousel entirely in HAL
Carousel is in LinuxCNC 2.7 and onwards.

net tool-num iocontrol.0.tool-prep-pocket => carousel.0.pocket-number
net tool-change iocontrol.0.tool-change => carousel.0.enable
net tool-confirm carousel.0.ready => iocontrol.0.tool-changed
net prep-loop iocontrol.0.tool-prepare => iocontrol.0.tool-preparedCarousel is in LinuxCNC 2.7 and onwards.

Thanks for your support, I really don't know how to implement it physically, the changer I'm designing has 6 tools, do you have any photos or diagrams of how to make it? In addition, I have not found any complete example of the configuration of an ATC for a lathe, most are for 3-axis machines, do you have any configuration that you can help me with?

What parts don't you understand? Are you looking for a complete mechanical design, or just help with the position feedback aspects?

Only position Feedback,The mechanical part is already working

I would probably use proximity sensors and drilled holes as targets.
Do you have any pics of the design or a 3D model to share?
