Help with turret encoder of Baruffaldi Turret TOE100 to retrofit old CNC

[m_c]

Are you manually rotating the turret to check the encoder outputs? That would be my first step. And I wonder whether the COM pin on the FX3U needs connecting to 0V perhaps?

Most likely this.

Easy way to test the encoder outputs, is with a multimeter. If you're getting voltage, then the encoder is at least doing something.

BTW, you probably don't want Strobe being used as part of the position calculation.
Strobe is used as part of the locking process and triggers the locking solenoid timing.
To calculate position, all you need are the Bits (A, B, C and D). You don't even need to use Parity, as it's sole purpose is to provide a basic value check.

I still have the PLC code to control a TOE80 using a Click PLC, but I no longer have the software installed to view it.
