This worked out incredibly well, especially with the tool changer!

I added a condition to the Delta PLC: if the tool access door is open, it won’t retract the tool into the spindle.
This was perfect for getting tools in and out of the machine.

Using a relay check stage followed by Gray code. I made a small board for the 12 sensors that detect the retracted state of each tool, using some NOT gates to consolidate the signals into a single input for the PLC. Once it sees that all tools are retracted, it extends the commanded tool.
After the tool is in the spindle, it sends a completion signal back to the Ethernet 1616.

I also added a condition to the Centroid macro / delta PLC so the bed won’t rotate until the machine does a tool check and the front doors have opened and then closed, making this part of the machine a lot safer.

The only thing left to do is add rigid tapping. I’ll post some videos soon!

thanks for the update, please post videos we all want to see!
