3DArtists has recently launched an Indiegogo campaign to try and fund the production of their Alligator control boards for reprap 3D printers. The boards function with both Cartesian an Delta-style 3D printers and start at just 160 euro. Additionally the company is making expansion boards available for add-ons such as additional extruders. Here are a few quick specs of the main Alligator boards:

  • CPU Cortex M3 Atmel ATSAM3X8EA-AU, Arduino-Due-Compatible
  • High Current connector for power input, bed and hot-end heatersa2
  • Power Input 12-24Vdc
  • 4x Stepper Motor driver running at 1/16 or 1/32 microstep and based on Texas Instrument DRV8825
  • 6x End-Stop input compatible with both mechanical and optical/magnetic solution
  • 2x Precision analog input for temperature measurement with RTD
  • 2x External FAN output with PWM speed control
