ONLY PCB without StepStick Driver

This is a board that's very similar to other Pololu-based electronics implementations, including RAMPS, but it can support up to 5 steppers (three for X, Y, Z, one for an extruder and one for any other function). You can add as many stepper driver carriers as you need. It is designed to run at higher voltages than 12 Volts, This allows you to put 90 Watts out of one MOSFET and run your stepper motors with more torque and higher maximum speeds. This board is also used on the Mantis-30 milling machine from Protospace and on various Mendel's that people have built.

Specifications

  • Arduino Mega Shield compatible
  • Plug in all motors with simple 4-way JST connectors.
  • Made for Ultimaker's UltiStepper Driver.
  • Compatible with Pololu stepper driver boards.
  • Controls up to 5 stepper motors (3 for the X, Y and Z axis one for an extruder (the "E axis"), optionally you can add another axis by adding a Pololu stepper driver.
  • Configurable step sizes by placing jumpers
  • 3x 55 Amp MOSFETs outputs (with LED indicators. Actual current capability limited by PCB and connectors)
  • All pins are broken out for maximum extensibility
  • Runs from 15V to 19V.
  • Three thermocouple inputs, or thermistor inputs. The 100K thermistor is recommended.
  • Has a IDC header for adding an LCD panel (movie here)
  • Has a header for adding an SD card module.
  • A toggle-switch for powering up/down the board
  • Easier to wire up thermocouples
  • Includes a 12V regulator for an (always on) fan to cool the electronics.
  • A PWM output with power for LED arrays and other lighting
  • LCD backlight dimming can now be software controlled
  • A serial I/O header for bluetooth and ethernet add-ons.
  • Servo outputs for experimental setups. They need to be interrupt or software driven as the pins routed to the servo header I/O do not have PWM.

New features and improvements of previous version:

  • Compatible with UltiController

- The Arduino Mega 2560 can be self-powered from the DC-jack. - Jumper added for controlling autonomous power setting - 100 uF connection to Vcc2 - High-current track from DC jack and ON/OFF switch moved slightly - Better suiting the footprint of the rocker switch

Marlin firmware compatibility is unaffected by this updated PCB.
