Name : Klipper
Author(s) : KevinOConnor
Status : Active as of September 2024
|
Firmware that runs all calculations on a host and has the MCU execute steps at specified times
|
| Features
|
- High precision stepper movement.
- High step rates even on 8bit.
- Kinematics algorithms, the G-code parsing, and more are in Python.
- Multiple microcontrollers supported on single printer.
- Configuration via single file, no need to flash MCU.
- Host software can run on Raspberry Pi.
- Supports Cartesian, Delta, and CoreXY. Adding more only requires changes to Python code.
|
| Compatible Electronics
|
- ARM, AVR, and PRU (portable code to make adding more easier.)
- Example configs for:

Name : Repetier
Author(s) : Repetier
Status : v1.0.3 (Active as February 2019, with v 2.x in development)
|
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
