You would have to wire the MPG encoder to one of the Hickory's 9-pin encoder inputs; then wire the axis-select and increment-select switches to discrete PLC inputs (using up between 6 and 9 of the 32 PLC inputs on the Hickory board). You would also need to wire one relay output for the MPG LED.

You ...

I will give another thumbs-down to any suggestion that Centroid should change to an annual subscription model.

Just because other companies have decided to treat their customers like sh*t, doesn't mean we should do so as well.

Buy it once, use it as long as you like. Spend a few $$ if/when you ...

Here is how I wired SGDA drives for velocity-mode control.

"457 ... unable to find home" is often because the control thinks that a touch probe is triggered.

You might want to review your probe, tool setter, and touch plate configuration, and the state of the associated inputs.

For troubleshooting, change Parameter 78 from 1 to 0, so that the spindle RPM shown in the status window is the commanded RPM from the PLC, rather than the measured RPM from the encoder.

When you do that, and run "M3 S1600", does the commanded RPM in the status window still say 0?

If it still says ...

Let us know how that custom M101 macro and Q parameter work out for you....

What he needs here is not "M26/C", but instead "G92 C0". Optionally both, in that order.

With the WCS offset already set to 65520 degrees, then immediately after power-up, the axis is at machine zero / machine home, but it is 65520 degrees away from part zero.

M151 resets machine position, not ...

If you move forward with the SGDA drives, you will have to accept some compromises related to error detection and emergency stop inhibits.

For control cables, I would start with the flying-lead cables (or cut the 50-pin connectors off your ...

A couple of style and convention comments:
; Check if Tool Setter Machine Ready (INP14) is active
; This sets ToolSetterReady_M if INP14 is active, otherwise, it will be RST by default below
IF TRUE THEN RST ToolSetterReady_M ; Default to OFF
IF INP14 THEN SET ToolSetterReady_M

Supposing that you ...

Yes, that would be an ID turning operation. The F7/Turn cycle is implicitly ID if you enter a Starting Diameter that is smaller than the Ending Diameter.
