BeBoPr-Plus Cape

This is a BeagleBone and 100% BeagleBone Black compatible version of the original BeBoPr Cape.

The BeBoPr Cape provides all the necessary I/O to control a Mendel/Reprap 3D-printer.

  • 3 analog inputs optimized for thermistors.
  • 6 digital inputs for limit switches.
  • 3 high-power PWM outputs for heater(s) and/or fan.
  • 4 axis steppermotor interface (5 axis via future expansion board) for either external drivers, or on-board StepStick/Pololu modules.
  • Single 12 Volt supply operation. The integrated 5V/2A switching stepdown convertor powers the BeagleBone, Cape and external Opto sensors.
  • All I/O is protected to prevent damage to the BeagleBone by accidental short-circuits.
  • Steppermotor operation at up to 24Volt.
  • LEDs mounted next to the input and output connectors provide status information.

All 'hard' realtime control, e.g. step pulse generation, acceleration etc. runs on a dedicated coprocessor that is part of the AM3359 on the BeagleBone. The 'soft' realtime control, e.g. traject planning, temperature control etc., runs on the ARM processor under Linux.

  • The stepper control code accelerates and steps all axes simultaneously at up to 60 kHz steprate.
  • The step-pulse duration on the E-axis can be controlled for laser engraving/cutter applications.

A license for the coprocessor code comes with the board. All Linux code is Open Source, the coprocessor code will be provided as a binary module.
