Project description
INTRODUCTION
This board is for small 3D printer/CNC with network connectivity and size is 82 x 60 mm
FEATURES
- 4 Stepper motor divers
- 2/3 Analog inputs (depending on network connectivity)
- Analog or digital Z-probe support
- 1 heated bed, 1 extruder, 1 fan control
- Micro SD-card
- I2C and I2S expansion ports
- USB 2.0 interface
- 4 End-stops including end-stops via current measuring on every stepper motor driver
- Network connectivity: Ethernet (W5500 module) or WiFi (ESP8266)
- 2 layer board, inexpensive to order (it might require applying additional solder on some power tracks and vias depending on desired current requirements)
- Firmware: RepRap, Klippe
TECHNICAL DETAILS
The firmware of this project use RepRap, Klipper. RepRap is started in England in 2005 as a University of Bath initiative to develop a low-cost 3D printer that can print most of its own components, but it is now made up of hundreds of collaborators worldwide.[1] RepRap is short for replicating rapid prototyper. The Klipper is a 3D-printer firmware. It combines the power of a genernal purpose computer with one or more micro-controllers
HOW TO USE
