Having looked into this some more, I don’t think it’s an impossible project by any means. What I’ve discovered is that the fourth axis (A axis) which I don’t use, can be used to turn a carousel. I would just need to add another motor.
in addition, I am typically not using flood coolant so I can use the output port for controlling that, to act a pneumatic switch, which would control the pick up or drop off of the tool.
some other standalone controllers have more output ports, unfortunately mine doesn’t, so I would have to hijack the coolant port.
obviously a bit of code would need to be written, but Grok assures me that it can do it for me (or at least it could give me a Headstart)
Perhaps not a project for now, but if I do find myself needing to do a lot of of CNC then it is certainly a possible thing to do with my set up.
