A Teen's Tiny 3D Printer Brainiac

A young innovator has created a compact powerhouse for 3D printers. This isn't just another small tweak. It's a whole new brain for these machines.

The Creator and the Cheetah MX4 Mini

The creator, a 17-year-old tech whiz, designed a control board called the Cheetah MX4 Mini. It's small, about the size of a drink coaster. But don't let its size fool you. It's packed with features.

Key Features

• Speed Chip: Uses a speedy chip called the STM32H743. This chip is like the central nervous system. It handles all the commands and makes sure everything runs smoothly.
• Stepper Drivers: Has slots for four stepper drivers. These are like the muscles. They control the printer's movements. The drivers are designed to be quiet. So, the printer won't sound like a jackhammer.
• Smart Features: Can figure out where it is without sensors. It's like a cat finding its way home in the dark. It also has spots for displays and memory cards. It can even power up to three fans and two high-power parts, like a heated bed.

Compact and Versatile

All these features are crammed into a tiny space. The board is about the size of a drink coaster. It's a marvel of miniaturization. The board supports two popular types of software. This means it can work with many different 3D printers. It's like having a universal remote for your TV. It just works with everything.

Why the STM32H743 Chip?

The creator chose the STM32H743 chip for a reason. It's fast and supports many protocols. This makes it versatile. The board also has slots for four TMC stepstick drivers. These drivers are known for their quiet operation. The board also has provisions for sensorless homing and endstops. This means the printer can figure out its position without extra sensors.

A Testament to Youthful Innovation

The Cheetah MX4 Mini is a testament to the power of youthful innovation. It's a small board with big capabilities. It's a reminder that good things come in small packages. It's also a reminder that age is just a number. This 17-year-old has achieved something remarkable. It's a feat that many adults would struggle to match.
