The eight stepper drivers slots can be used to build a 3D printers with 8 axis, so besides the normal X,Y,Z and Extruder drivers you can add another 4. This enables you do do fancy things like leveling the bed automatically, or color mix filament. The Octopus Pro version also allows you to run the stepper drivers on 60V for even higher torque, resulting in more reliable and faster movements. The Octopus Pro v1.0 comes with five thermistor headers to connect a 100K thermistor. Also a MAX31865 chip is on-board for connecting up to two PT100 or PT1000 thermo couples.
