Grbl

FIRMWARE INFO
Details Description

Name : Grbl
Author(s) : Simen Svale Skogsrud
Status : active as of May 2014

Grbl is a no-compromise, high performance, low cost alternative to parallel-port-based motion control for CNC milling. Does not control extruders.
Features
  • run on a vanilla Arduino (Duemillanove/Uno) as long as it sports an Atmega 328
  • nice simple controller for CNC milling
  • written in tidy, modular C
  • does not require parallel port
  • able to maintain more than 30kHz step rate and delivers a clean, jitter free stream of control pulses.
  • full acceleration-management with look ahead planner
Compatible Electronics
How to download

Downloadable from github by running:

git clone https://github.com/simen/grbl.git
Documentation & Misc. Notes

Documentation is at http://dank.bengler.no/-/page/show/5471_gettinggrbl

From the website:

We have limited g-code-support by design. Grbl support all the common operations encountered in output from CAM-tools, but leave human g-coders frustrated. No variables, no tool offsets, no functions, no arithmetic and no control structures. Just the basic machine operations. We have yet to find a CAM-generated file that failed to run, though.
  • No gui, all interaction is through command line

Repetier-Firmware

FIRMWARE INFO
Details Description

Name : Repetier
Author(s) : Repetier
Status : v0.92 (Active as March 2015)

forked from Sprinter.
Features
  • RAMP acceleration support.
  • Path planning (look ahead) for higher print speeds. (since version 0.32, 2011/9/24)
  • Fast ooze prevention system. (since version 0.35, 2011/10/8)
  • Trajectory smoothing for smoother lines. (since version 0.32, 2011/9/24)
  • Nozzle pressure control for improved print quality with RAMPS. (since version 0.32, 2011/9/24)
  • Fast - 16000 Hz and more stepper frequency is possible with a 16 MHz AVR. (since version 0.32, 2011/9/24)
  • Multiple extruder supported (experimental).
  • Standard ASCII and improved binary (Repetier protocol) communication.
  • Autodetect the command protocol, so it will work with any host software.
  • Continuous monitoring of one temperature.
  • Important parameters are stored in EEPROM and can easily modified without recompilation of the firmware.
  • Stepper control is handled in an interrupt routine, leaving time for filling caches for next move.
  • PID control for extruder temperature.
  • Interrupt based sending buffer (Arduino library normally waits for the recipient to receive written data)
  • Small RAM memory print, resulting in large caches.
  • Supports SD-cards.
  • mm and inches can be used for G0/G1
  • Works with Skeinforge 41, all unknown commands are ignored.
  • Dry run : Execute your GCode without using the extruder. This way you can test for non-extruder related failures without actually printing.
  • User defined and generic thermistor table( just set r0,t0,beta,r1,r2) in config (since version 0.31).
  • LCD support

Aprinter

FIRMWARE INFO
Details Description

Name : Aprinter
Author(s) : Ambroz Bizjak
Status : Active as of Nov 2015

Aprinter is a portable firmware system, written from scratch in C++ with a heavy dose of template metaprogramming. A web-based configuration system is used to configure the high-level features for a particular machine, but also to define the low-level configuration for supporting different controller boards.
Features
  • Linear-delta, rotational-delta and CoreXY support. New geometries can be added by implementing a foward and inverse coordinate transformation. A processor with sufficient speed and RAM is needed (not AVR).
  • Bed probing using a digital input line (e.g. microswitch). Height measurements are printed to the console.
  • Bed height correction, either with a linear or quadratic polynomial, calculated by the least-squares method.
  • SD card and FAT32 filesystem support. G-code can be read from the SD-card. Optionally, the SD card can be used for storage of runtime configuration options. A custom (fully asynchronous) FAT32 implementation is used, with limited write support (can write to existing files only).
  • Ethernet network (currently on Duet only). Gcode console over TCP is supported (equivalent to the serial-port interface), with multiple concurrent connections. Pronterface can connect this way.
  • Supports heaters and fans. Any number of these may be defined, limited only by available hardware resources.
  • Experimental support for lasers (PWM output with a duty cycle proportional to the current speed).
  • Supports multiple extruders. However, the interface is not compatible to typical firmwares. There are no tool commands, instead the extruders appear as separate axes. A g-code post-processor is provided to translate tool-using gcode into what the firmware understands. This post-processor can also control fans based on the "current tool".
  • Unified runtime configuration system. Most of the "simple" configuration values which are available in the configuration editor have the corresponding named runtime configuration option (e.g. XMaxPos). Configuration may be saved to and restored from a storage backend, such as an EEPROM or a file on an SD card.
  • Homing of multiple axes in parallel.
  • Homing cartesian axes involved in a coordinate transformation (e.g. homing X and Y in CoreXY).
  • Slave steppers, driven synchronously, can be configured for an axis (e.g. two Z motors driven by separate drivers).
  • Constant-acceleration motion planning with look-ahead. To speed up calculations, the firmware will only calculate a new plan every N ("Lookahead commit count") commands. This allows increasing the lookahead without an asymptotic increase of CPU usage, only limited by the available RAM.
  • High precision step timing. For each stepper, a separate timer compare channel is used. In the interrupt handler, a step pulse for a stepper is generated, and the time of the next step is calculated analytically.
Compatible Electronics
  • Duet.
  • RAMPS-FD, RADDS or other setup based on Arduino Due.
  • 4pi.
  • RAMPS 1.3/1.4 (only atmega2560).
  • Melzi (only atmega1284p).
  • Teensy 3.1/3.2 (no specific board).
  • STM32F4-Discovery, STM32F429I-Discovery (no specific board).
