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.
