Imprimanta 3D (1) – Sursa de tensiune si Controller-ul

De curând am început lucrul la o imprimanta 3D Prusa i3
Primul pas l-am făcut cumpărând o sursa serioasa și un controller pentru motorașe.

Controller-ul este un Arduino Mega 2560 ce are suficienți pini I/O pentru imprimanta mea.

Microcontroller ATmega2560
Operating Voltage 5V
Input Voltage (recommended) 7-12V
Input Voltage (limits) 6-20V
Digital I/O Pins 54 (of which 15 provide PWM output)
Analog Input Pins 16
DC Current per I/O Pin 40 mA
DC Current for 3.3V Pin 50 mA
Flash Memory 256 KB of which 8 KB used by bootloader
SRAM 8 KB
EEPROM 4 KB
Clock Speed 16 MHz

 

Sursa pe care o folosesc este una de 12 V și 29 A. Cred ca corespunde perfect aplicației meu.


Le-am și conectat și cred că se înțeleg destul de bine 🙂

Am folosit conector alimentare AC Standard IEC60320 cu întrerupător pentru ca o sa montez sursa într-o carcasa potrivita ;).

Ar urma în pasul următor driverele pentru motoare și motoarele Nema17 iar apoi componentele mecanice. Din cate am auzit parte mecanica ar fi cea mai complicata .
