BIGTREETECH Octopus MAX EZ V1.0 User Manual

Product Profile

BIGTREETECH Octopus MAX EZ is an optimized 32-bit 3D printer control board

based on the Octopus Pro, using self-developed stepper motor driver sockets to

enhance safety and user experience, with many new features not found on

Octopus Pro to increase DIY potential.

Feature Highlights

32 bit 550 MHz ARM Cortex-M7 series STM32H723ZET6 MCU;

Onboard BOOT button to enable DFU mode to update bootloader;

The thermistor circuit is protected to prevent MCU damage from shorted

heated bed and heater cartridge connections;

Selectable voltage (24V, 12V, 5V) for CNC fan, eliminating the need for

external buck modules, thereby reducing the likelihood of motherboard

damage.

Upgraded with eFuse protection, which responses faster with strong

protection, effectively protecting the motherboard from being damaged

caused by short circuits, over-current, electric spark, etc.

MCU firmware can be upgraded via SD card, or use DFU via Klipper's make

flash command;

10 EZ driver sockets, working with pinless driver, safer to use; Onboard SPI

and UART, can be used by simply setting in the firmware, no need for a

jumper.

Support power loss recovery, filament runout sensor, CAN, auto power-off,

BLTouch, RGB, etc;

Replaceable fuse for easy maintenance;

3 x 4 pins fan ports, also for connecting water cooling system;

Onboard proximity switch port, supports NPN and PNP types, 24V, 12V, 5V

voltage selectable;

Onboard SPI interface for connecting acceleration sensor to enable Klipper's

input shaping.

Connection Description

USB Power Supply

After the Octopus MAX EZ has been powered, the Red light D32 on the left side

of the MCU will light up, indicating power on. When using only USB to power the

board or to supply power via USB, please insert the jumper cap onto the VUSB.

Stepper Motor Driver

UART/SPI Mode of Driver

Set in the firmware, no need for a jumper.

TMC Driver DIAG (Sensorless Homing)

When using sensorless homing, place jumpers according to the diagram below,

there is no need to cut the DIAG pin off when not being used. (Motor1-Motor6).

Driver Voltage Selection

BIGTREETECH Octopus MAX EZ V1.0 User Manual

Voltage Selection for CNC Fan

The output voltage can be set to 5V, 12V or 24V through a jumper. (MFAN and

FAN6 share the power supply VFAN6).

Note: Verify the fan's rated voltage before selecting to avoid damage. We are not

responsible for fans burnt due to incorrect voltage selection.

100K NTC or PT1000 Setting

When using 100K NTC, no jumpers need to be connected, the pull-up resistance

of TH0-TH3 is 4.7K 0.1%. When using PT1000, the pins indicated in the picture

below need to be connected via jumpers, parallel connection of 4.12K 0.1%

resistors, the pull-up resistance of TH0-TH1 is 2.2K. (Note: this method has a

much lower accuracy than the MAX31865 in reading temperature.)
