<<<<<<< HEAD A new beta version is avaiable. Look under the Marlin_v1 branch. We also made a tag that you can download. This firmware is a mashup between Sprinter, grbl and many original parts. (https://github.com/kliment/Sprinter) (https://github.com/simen/grbl/tree) 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 For more info see: http://reprap.org/pipermail/reprap-dev/2011-May/003323.html 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 https://github.com/kliment/Printrun 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) ======= This RepRap firmware is a mashup between Sprinter, grbl and many original parts. (https://github.com/kliment/Sprinter) (https://github.com/simen/grbl/tree) Derived from Sprinter and Grbl by Erik van der Zalm. Sprinters lead developers are Kliment and caru. Grbls lead developer is Simen Svale Skogsrud. It has been adapted to the Ultimaker Printer by: Bernhard Kubicek, Matthijs Keuper, Bradley Feldman, and others... 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 For more info see: http://reprap.org/pipermail/reprap-dev/2011-May/003323.html - Full endstop support - Simple LCD support (16x2) - SD Card support - Provisions for Bernhard Kubicek's new hardware control console and 20x4 lcd This firmware is optimized for Ultimaker's gen6 electronics (including the Ultimaker 1.5.x daughterboard and Arduino Mega 2560). The default baudrate is 115200. ======================================================================================== Configuring and compilation Install the latest arduino software IDE/toolset (currently 0022) http://www.arduino.cc/en/Main/Software Install Ultimaker's RepG 25 build http://software.ultimaker.com (or alternatively install Kliment's printrun/pronterface https://github.com/kliment/Printrun_) Copy the Ultimaker Marlin firmware https:/github.com/bkubicek/Marlin (Use the download button) Start the arduino IDE. Select Tools -> Board -> Arduino Mega 2560 Select the correct serial port in Tools ->Serial Port Open Marlin.pde Click the Verify/Compile button Click the Upload button If all goes well the firmware is uploading Start Ultimaker's Custom RepG 25 Make sure Show Experimental Profiles is enabled in Preferences Select Sprinter as the Driver Press the Connect button. KNOWN ISSUES: RepG will display: Unknown: marlin x.y.z That's ok. Enjoy Silky Smooth Printing. >>>>>>> Mendel
