Product description
Build a blazingly fast and powerful 3D printer with the BigTreeTech Octopus v1.1! This impressive 3D printer controller board provides eight stepper and many other peripherals. The fast 180MHz processor has a large memory to run multiple firmwares like Klipper, Marlin and RepRapFirmware.
The Octopus v1.1 can be connected to a LCD12864 LCD screen or TFT screens as well as multiple fans, eight stepper drivers and BLTouch auto bed leveling module.
Stepper drivers
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.
Temperature reading
The Octopus v1.1 comes with five thermistor headers to connect a 100K thermistor. For PT100/PT1000 support you can check the Pro version
Communication
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.
Safety features
The board Octopus v1.1 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.
