Phoenix Electronics
Phoenix is a robust, modular through hole RepRap electronics designed to be easy for beginners to construct.
History
In 2011 a few of us started the Thames Valley RepRap group [TVRRUG] to connect RepRap folk in the area and to embark on build groups designed to bring new folks into the RepRap 3D printing revolution. As part of this we started refining our Mendel Prusa based design and were looking to improve on the existing electronics. We wanted to solve a few of the current design issues as well as move away from the more expensive Pololu-based drive modules (Early build discussions). Here are some of the main features we decided as a group:
- Completely through hole component design to make construction accessible to a wider range of folk
- Modular so that single or Multiple extruder designs could be catered for
- Self maintainable if you can build it you can replace its modules and or components
- Robust we had experienced thermal and power issues with the existing electronics we figured we could improve on that
Design
The design is modular and consistis of a main controller board (OMC) and up to 3 Stepper modules (DSMs), each of which is capable of handling 2 stepper motors. This allows for designs from the basic single extruder up to more complex builds using three extruders.
- Atmel ATmega644 based controller design
- Up to 3 extruders (requires 3 DSM modules)
- High capacity Heated bed support (up to 20 Amps DC)
- Onboard SDCard
- Power sequencing (to protect those Tosh drivers)
We currently support Marlin firmware
Current version is 1.2 - Kit Parts, Build Instructions & Wiring
