Save time and upgrade to the COMBO Kit.
HobbyCNC PRO COMBO Kits include:
- HobbyCNC PRO Stepper Motor Driver Kit 3 or 4 axis
- Stepper motors in same quantity as driver board channels (sorry no mix of motor sizes)
- 14′ of 6 conductor stranded stepper motor hookup cable
- M-F Parallel port cable 6′ long
HobbyCNC Kits require PCB soldering skills

|9||A Step||All others||Not Connected|
|* The actual function of these pins is determined in the CAM software|
|** Pins 1, 14, 16 & 17 are made available via solder pads. Nothing is done to these lines on the PRO board. Straight from the D connector to the solder pads.|
