Status

Currently (01/Jan/2013) are 10 boards ready for shipment, it was the prototype batch. If you are interested, please contact the author under his e-mail address to get further informations and pricing. You can find it at the end of this page.

Introduction

Aim of this project is to make an electronics which gives the beginner a kit consisting of all electronic parts he needs to build a printer plus some spare parts which often die during the initial experiments with the printer. The board should have some comfort for easy stand alone printing. As a result ist has 4 stepper driver on board for X- Y- Z-axis & Extruder, heater outputs for the nozzle and the printing bed, USB communication, SD Card interface and a comfortable user interface with LCD & clickwheel. Important for beginners, the board runs from 12V..24V. It has a built in reverse polarity protection. Even if the user is not familiar with the new hardware it often happens that a wrong power connection can kill the whole electronics, the reverse polarity protection prevents damage.

  • Reverse polarity protection
  • 12V to 24V operating voltage
  • Processor ATmega1284p runs at 20MHz
  • Graphic LCD 128x64 pixel
  • Click encoder wheel
  • 4 Stepper channels (X-Axis, Y-Axis, Z-Axis(2 connectors for 2 motors), Extruder)
  • 3 Endstop inputs
  • Heatbed
  • Nozzle
  • Fan output (5V or 12V/24V depends on power supply)
  • SD-Card
  • USB-Connector

All in one Solution

The board batch consists of more than the control electronic. Also on it are 6 stepper drivers (Pololu compatible) and 4 opto endstops. So the beginner has all the electronic parts he needs plus two spare stepper drivers and one spare endstop.

User Interface

The user interface is the same as known from the Ultipanel (at Thingiverse). It uses a click wheel encoder to navigate through the menus. Compared to the original Ultipanel it has more flexibility because of the dot matrix display. The pictures give some impression on it.

Firmware

The Firmware is based on EricZalm's Marlin. Only a few modifications must done. I hope Eric will include the necessary changes in Marlin. I'm currently working on the final documents for the pull request.
