2. General description

Electronics description

This device consists of two separate main modular components: the Pr3Dator and the HMI panels.

The Pr3Dator board’s main function is controlling the printer itself while the HMI board is res

ponsible for the user interactions.

The Pr3Dator board can maintain the machine operation by itself, if the machine is controlled

using USB.

Pr3Dator:

The Pr3Dator board is based on the high performance ARM Cortex M3 Atmel SAM3X processor, which

operate at 84MHz. The operating firmware is written and maintained by CraftUnique.

The Pr3Dator board runs the motor controllers, plus the heating and cooling.

Its voltage range is from 12V to 36V. All current CraftBot models are using 24V for driving the

motors. The 24V is used solely by the Pr3Dator board; the HMI is driven using 12V, which is pro

vided by the Pr3Dator board.

All the fan units use a standard 12V, as there are no separate special fans needed.

The units is fitted with a real time clock (RTC) configuration which keeps the time while being

powered off.

The Pr3Dator board executes all of it’s commands based on the gcode.

Communication between the Pr3Dator and the HMI boards is done through special mcodes.

USB:

The USB (Universal Serial Bus) provides a wired connectivity between a USB host PC and the

CraftBot itself.

USB is a differential serial bus for USB devices. The USB controller supports USB specification

revision 2.0 in accordance with the full speed USB (12 Mbps). The device is connected to the USB

host using a USB-B connector. The USB bus utilizes hot plugging capabilities, which means that

USB devices may be plugged in/pulled out at any time.

HMI:

The HMI board is based on the high performance ARM Cortex M3 Atmel SAM3X processor, which opera

tes at 84MHz. The operating firmware is written and maintained by CraftUnique.

The HMI board controls the functions of the LCD display, backlight, interior lights, beeper, and

thumb drive.

WiFi module:

The WiFi module provides a fully digital link enabling communication between the CraftBot and

the CraftApp. The WiFi module is for CraftBot 2 models only, and it’s operation is supported

with the HMI board. The WiFi module runs on a frequency of 2.4 GHz. It is compatibile with the

802.11b/g/n standards.

Power:

The power is provided by a single voltage power supply; the other neccessary voltages are gene

rated by the Pr3Dator / HMI board respectively.

The power supply has no standby state, so it has to be switched off when the device is not in

use.
