Hello,


i have 3 axis milling machine, retrofitted with Linuxcnc + 5i25 + 7i77, with analog servo drives.
Now i want to add separated rotary table. But the table is with stepper motor. Can I add to system one parallel port Step/Dir card, to control the rotary table?
Know Linuxcnc to control analog +/-10V servos together with stepper motor?

You can also use the second 5I25 connector and a simple breakout to get hardware stepgens
