Description

The Prusa i3 (iteration 3) is the newest and current 3D Printer design by RepRap Core Developer Prusajr. The i3 incorporates lessons learned from the previous two Prusa designs, as well as other popular modern RepRap designs.

Main improvements

The following is a list of the main improvements made upon the Prusa Mendel Iteration 2

  • enhanced frame rigidity (prevents x backlash)

  • easy assembly

  • parametric files for multiple sizes/bearings or bushings

Stepper Motors

The Prusa i3 uses, including the extruder, 5 NEMA17 stepper motors. Two of these motors, the Z axis motors, are connected to the same stepper driver of the electronics. If using Wade's Extruder, its stepper motor needs a minimum holding torque of 40Ncm (0.4Nm) which is included.

Controller Electronics

This kit contains a Megatronics board with all stepperdrivers (Stepstick A4988) included and you can connect the steppermotors easily on the board.

Megatronics has a powerful Atmega2560 processor with 256 kB memory, running at 16Mhz. The board can be connected to a PC using a normal USB cable. It will register as FTDI FT232R device. The board is compatible with the Arduino Mega 2560 and will therefor be easily programmed from the Arduino IDE.

Major features

Atmega2560
Powerful Atmega2560 processor with 256 kB memory, running at 16Mhz

Thermo couple (2x)
On board support for connecting two thermo couples

SD Card
Autonomous printing from Micro SD card on board

LCD support
Hooking up a LCD is pretty easy. The Wiring is compatible with most LCD screens.

Five MOSFETs
The board has 4 MOSFETs (4x 25A) to support fans and extruders and 1 MOSFET (IRLS3034PBF) for the heated bed

Up to 6 stepper drivers
Compatible with RAMPS, 6 slots for stepper drivers (not included). Modularized to make replacement easy for damaged drivers.

Support for many peripherals
The board's functions can be easily extended with LCD, keypad etc. See the connectors section for more information
