AXXB-E where to take step and dir signal for B and C axes

hi AXBB-E I was wondering where to get the step dir signals for the B and C axes. Thanks

You can use any output free output. O1 is charge pump only, O2 to O8 are open collector outputs on the 24V, so use O9 to O17 or port 3 with or without a breakout board, depending on your motor drivers.

thanks for the answer, but I don't understand. I use pin 8 and 9 for axis X, pin 11 and 12 axis Y, pin 13 and 14 axis Z, pin 15 and 16 axis A. It remains free only pin 17 for axis B, certainly not enough, what to do to complete the axis B and axis C. I don't understand, Perhaps this is the solution:Scheda breakout UCSB a porta singola + 1xIDC26-IDC26_cavo da 250 mm ????

Yes, that is what I wrote. You didn't mention the type of your motor drivers. Most of them can be connected directly to the port 3, but if not then use the UCSB.

ho capito il driver è HBS86H. Grazie.

That has optoisolated inputs, so you can connect directly to port 3.
