Build a blazingly fast and powerful 3D printer with the BigTreeTech Octopus Pro v1.0! This impressive 3D printer controller board provides eight stepper slots that can be run at up to 60V for the fastest movements without losing steps. The fast 168MHz processor has a large memory to run multiple firmwares like Klipper, Marlin and RepRapFirmware.
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. So the TMC5160 Pro V1.0 can be use to achieve the best performance. Each stepper driver can be switch between SPI, UART and Step/dir communication using jumpers for a broad spectrum of possibilities. Finally each driver has a optocoupler to protect the mainboard.
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.
This controller board provides multiple options to communicate. Of course the Octopus provides a USB-C header for a connection to a computer and a microSD slot for printing gcode files directly. For more advanced features a CANbus interface with RJ11 connector is available and the board can be extended with an ESP8266 Wifi module for network connectivity.
The board Octopus Pro v1.0 has optocouplers to create a galvanized separation between stepper driver and mainboard circuits. This protects the main board circuit from damage by faulty or reversed stepper drivers. Also the board has multiple fuses to protect the different circuits from overcurrent, avoiding damage to the board when shorts occur.
