- Mar 3, 2013Hi Dustin,
I took a look at that drive, cool one!
You want to operate the drive in position mode with the encoder feedback
to the drive. The step and direction outputs of the Smoothstepper is
then connected to the auxillary encoder connector (P3) on the drive. A
breakout-board isn't strictly needed (it rarely is) but it almost always
makes wiring the system up a lot easier. There are a couple of break-out
boards specifically made for the Smoothstepper available, might be worth
You can feed the encoder back to the Smoothstepper as well as to the
drive (but you don't have to). It will allow you to SHOW the actual
position in Mach3. The actual position-loop is handled by the drive
though. I'd probably let this be until you get the rest going.
Apparently you need to get a CAN-interface for the PC in order to
configure and tune the drive, that kind of sucks since you're not
actually going to USE the CAN-interface in operation. Oh well....
