Smoothieboard 5XC 5X V1.1 ARM Cortex-M3 Open-Source Motherboard 32 Bit LPC1769 with Ethernet

3D Printer Smoothieboard 5XC 5X V1.1 ARM Cortex-M3 Open-Source Motherboard 32 Bit LPC1769 Control Support Ethernet

 Smoothieboard is an Open-Source Hardware CNC controller designed by the Smoothie community to run the Smoothieware firmware. Its main design goals are:

– Uses as powerful hardware as possible at the time

– Can control several machine types (3D printers, lasers, CNC mills/routers).

– Easy to set up and use.

– Easy to do the wiring.

– The board uses the LPC1769 microcontroller, an ARM Cortex-M3.

– 32-bit architecture.

– 120Mhz frequency

– 512kB ROM (program space)

– 64kB RAM (execution memory)

USB

The USB interface connects to a host (your computer), and can be used :

– Via its USB/MSD (Mass storage) interface to directly access the SD card in the board (read, edit, copy/paste files).

– Via its USB/CDC (Serial) interface to send commands (like G-codes) for execution, for example using host software.

This allows for pretty things like:

–  Editing the configuration without having to edit the source file or reflash the firmware.

– Dropping Gcode files to the board and executing them.

– Dropping firmware upgrade files to the board for easy flashing See USB.

Ethernet

The Ethernet interface allows you to connect the board to your local network (LAN). You can then use different protocols to talk to the board: HTTP to use web interfaces hosted on the board, or via using host software that supports this Telnet to send commands via a serial interface, or via using host software that supports this.

Stepper motor drivers

Stepper motors are used to move axes on your machine or turn extruders. You plug them into stepper motor drivers on your Smoothieboard. The drivers on the v1 board are A5984 drivers which offer :

– 1/32 ( quieter ) micro-stepping.

– Several protections making them sturdier.

– Digital ( configuration-file set ) current values, no potentiometer manipulation.

– Great heat-sinking allowing the use of their full 2A current rating, for more torque/speed.

– The Smoothieboard 3X has 3 drivers, the 4X has 4 drivers, and the 5X has 5 drivers, thus their names.

MOSFETS

Mosfets are transistors for high loads. They are essentially digitally controlled “switches”. Your microcontroller can choose if they are let electricity pass or not. This is useful to control heating elements (like hotends and heated beds), fans, and other power-oriented peripherals. Smoothieboard v1 has two types of Mosfets:

– Small ones for fans, hotends, and other low loads (5A, up to 24V).

– Large ones for heated beds, powerful hotends, and other high loads (12A, up to 24V).

– Smoothieboard 3X has two small MOSFETs, Smoothieboard 4X has two small and two big MOSFETs, and Smoothieboard 5X has three small and three big MOSFETs.

Temperature reading

All v1 boards come with 4 temperature reading inputs. These can be used to read the resistance of thermistors in your hotend or heated bed, inferring from it its current temperature, and from this the temperature control module can regulate the temperature by choosing whether to heat it or not.

Endstops

The board has 6 endstop inputs. These can be used for limit switches at the end of the axes, used to limit motion within the work area, or for homing to origin. They can also be used to connect probes, for example for bed leveling or automated machine calibration.

Power inputs

Smoothieboard has the main power input that supports from 12 to 24V. Each MOSFET pair must also be powered via its own, separate input, supporting from 12 to 24V. The board’s logic power can be provided via USB, via the 5V power.
