MOOZ, the industrial grade transformable metallic 3D printer, which takes all-in-one design with interchangeable heads for 3D printing, laser engraving and CNC carving. The industrial grade linear guideway, stepper motor and CNC-machined body keeps MOOZ stable and 0.02mm high precision. Quick assembly, protective case, easy-to-use controller, and intuitive guide make MOOZ suitable for beginners, makers and educators. MOOZ has won the iF DESIGN AWARD 2018 for the innovative design and multiple functions.
For more information, refer to Product details.
The hardware platform for MOOZ consists of pieces of PCBA boards, all developed by the MOOZ team. The main controller is STM32F407ZG, a high performance ARM Cortex-M4F MCU. In addition to basiclly develop a normal 3D printer, which communicates with host via Serial port, we added some extra features on the hardware platform and for the product, like USB disk and SD card read/write, UART HMI operation, etc.
The original version of MOOZ 3D Printer Firmware is forked from the repository Marlin4ST 1.0.X. As it describes,
This repository proposes an example firmware for the ST Microelectronics 3D printer board STEVAL-3DP001V1. The Marlin4ST firmware relies on STM32Cube0 and integers the 3D printer algorithms from the Marlin 1.0.X firmware. The official Marlin 1.0.X firmware is now closed.
The original project Marlin4ST 1.0.X uses OpenSTM32 toolchain. At the very beginning, the MOOZ team chooses the same toolchain, but at last, the team chooses MDK-ARM Microcontroller Development Kit, for development efficiency and easy integration of drivers for new features.
The hardware is almost all different from that of STEVAL-3DP001V1. We did a lot of work to make it run, which consists of,
- Change clock source of the controller
- Change nearly all the I/O maps for motor direction and pulse control, temperature sampling, heating, etc., and the corresponding initialization code
- Adaption for any other hardware differences
On the MOOZ product, we propose a Bootloader--Application architecture, to make it easily and safely for users to upgrade the application firmware, and no need to disassemble the integrated structure of MOOZ.
For users who want to customize MOOZ 3D printer firmware,
- Select suitable toolchains
- The total flash memory for STM32F407ZG is 1M Bytes, and the bootloader memory is designed between 0x08000000 and 0x0803FFFF(256kB). The total memory size reserved for application is 768kB
- Change to start address of application code and the base address of interrupt vector table to 0x08040000
- Build the project
- Generate the application binary file using fromelf
- Rename the binary to
MOOZ1V1.2.3.binorMOOZ2V3.4.5.binstyle name, prefix withMOOZ1for MOOZ-1Z product, andMOOZ2for MOOZ-2Z product - Copy the binary file to the root directory of USB disk or SD card, and re-power the MOOZ
- Wait for the application upgrading
The original project runs the controller on 16MHz frequency using internal clock source. To fully utilize the performance of the controller, we runs MOOZ on 84MHz.
Add fan PWM control, which is not provided by the original project.
Add external SPI Flash to store some importance configuration of MOOZ.
Though the original project supports file system over SD card, it still needs some work.
- Change the FatFs porting code to support multiple storage instance
- Integrate
STM32_USB_HOST_Libraryto support USB disk driver. Also we can do a lot besides this by implementing different class drivers - Configure the FatFs to add
Long File Name Supportfeature
The operation panel of MOOZ is an UART HMI. In addition to add software driver for it, we designed a full set of UI on it. The HMI acts as a host on this platform.
GitHub is a community that admires highly of sharing, and we would like to open the source code of the MOOZ 3D printer firmware, to follow this virtue of sharing, and meanwhile to collect excellent feedbacks and opinions from you, to encourage the MOOZ team to make a better product in the next generation. Let's move on! Join this forum to get more support: MOOZ Forum.
