Not as such - as with Zeeflyboy the Pi is connected to the Ramps board via a short USB cable and the Ramp board uses 4 wire stepper wiring, which is likely the same as you would use for a CNC router.

The board is shown here (scroll down a bit for the schematic): https://www.hic3dprinter.com/collect...e-mother-board
Ah that makes sense now. The ramps I was looking at didn't have usb, only a shield for the Aurduino.

More options to look for now, thanks
