This firmware is a mashup between Sprinter, grbl and many original parts.
|
|
(https://github.com/kliment/Sprinter)
|
|

|
|
|
|
Features:
|
|
- Interrupt based movement with real linear acceleration
|
|
- High steprate
|
|
- Look ahead (Keep the speed high when possible. High cornering speed)
|
|
- Interrupt based temperature protection
|
|
- preliminary support for Matthew Roberts advance algorithm
|
|

This firmware is optimized for gen6 electronics.
|
|
|
|
The default baudrate is 250000.
|
|
This gives less communication errors then regular baudrates.

Configuring and compilation
|
|
|
|
|
|
Install the arduino software version 0018
|
|
http://www.arduino.cc/en/Main/Software
|
|
|
|
Install the sanguino software, version 0018
|
|
http://sanguino.cc/useit
|
|
|
|
Install pronterface
|

|
|
|
|
Copy the Marlin firmware
|
|
https:/github.com/ErikZalm/Marlin
|
|
(Use the download button)
|
|
|
|
Start the arduino IDE.
|
|
Select Tools -> Board -> Sanguino
|
|
Select the correct serial port in Tools ->Serial Port
|
|
Open Marlin.pde
|
|
|
|
Change the printer specific setting in Configuration.h to the correct values.
|
|
|
|
The following values are the most important:
|
|
- float axis_steps_per_unit[].... // Set the correct steps / mm in the corresponding field
|
|
- const bool ENDSTOPS_INVERTING = false; // Change if only positive moves are executed
|
|
- #define INVERT_x_DIR true // Change if the motor direction is wrong
|
|
|
|
Click the Upload button
|
|
If all goes well the firmware is uploading
|
|
|
|
Start pronterface
|
|
|
|
Select the correct Serial Port. Type 250000 in the baudrate field.
|
|
Press the Connect button
|

Known issues
|
|
|
|
On some systems we get compilation errors.
|
|
|
|
This is caused by the "wiring_serial.c" and "wiring.c".
|
|
The simple fix is to delete these files but this may have a performance impact.
|
|
|
|
The best workaround is to move these files to sanguino directory.
|
|
(".../arduino-0018/hardware/Sanguino/cores/arduino/" on windows systems)
