The leading developers of Sprinter are currently Kliment, caru and
|
|
midopple, though many others contribute with their patches.
|
|
|
|
This is a firmware for RAMPS and other reprap single-processor
|
|
electronics setups. It supports printing from SD card, active heatbed
|
|
control, and ATmega internal pullups.
|
|
|
|
This work is licensed under the GNU GPL v3 or (at the user's
|
|
discretion) any later version.
|
|
|
|
It is based on Tonokips's firmware, which was licensed under GPL v2 or
|
|
later.
|
|
|
|
WARNING: This version (April 19th, 2011) fixes a bug that caused
|
|
speeds to be lower than what set in GCODE. So before attempting
|
|
any print, you will have to check all your axis max speed,
|
|
including the extruder retract speed. Not following this
|
|
guidelines can seriously damage your printer.
|
|
|
|
The configuration file now has an option to set the wanted temperature
|
|
table file. If you copy and paste a temperature file from older
|
|
versions, make sure that the configuration is pointing to it. For
|
|
example: #include "ThermistorTable.h"
|
|
|
|
In addition, you can optionally use a different thermistor table for
|
|
hot-end and bed. To do so, comment out the following lines in
|
|
configuration.h:
|
|
#define BNUMTEMPS NUMPTEMPS
|
|
#define bedtemptable temptable
|
|
|
|
Then add a line pointing to your second thermistor table, for example:
|
|
#include "BedThermistorTable.h"
|
|
|
|
Finally, make sure that the nozzle thermistor table, inside
|
|
ThermistorTable.h in this case, is defined as "temptable" and that the
|
|
bed thermistor table is defined as "bedtemptable", and that the number
|
|
of temps is defined as NUMTEMPS for the heater and BNUMTEMPS for the
|
|
bed.
|
|
|
|
There are examples of all these configurations in the configuration.h
|
|
file. Please look at them before you change anything.

Complete beginners guide
|
|
=======================
|
|
|
|
From a fresh Ubuntu install how to update the firmware of your Prusa
|
|
Mendel ? (the specifics are for the Prusa Mendel built at the Bath
|
|
RepRap masterclass. This version uses the
|
|
http://reprap.org/wiki/Sanguinololu. Some details may not fit your
|
|
hardware, be sure to check what you are doing)
|
|
|
|
Steps 3,10,11 are hardware-specific to the Sanguinololu and Bath Prusa
|
|
and should be skipped or modified accordingly for other hardware such
|
|
as the Arduino Mega 2560
|
|
|
|
Software installation
|
|
----------------------
|
|
|
|
1. Install the required packages (gcc-avr, avr-libc, etc.)
|
|
sudo apt-get install arduino-core
|
|
|
|
2. Get the arduino software version 0023, uncompress it in a
|
|
directory. Arduino software v1 has not been tested much, but is known
|
|
to work with some boards.
|
|
http://www.arduino.cc/en/Main/Software
|
|
|
|
3. Get the sanguino software, version 0023
|
|
http://sanguino.cc/softwareforlinux
|
|
|
|
follow the sanguino's readme so that your arduino hardware folder looks like
|
|
arduino-0023/hardware/arduino
|
|
arduino-0023/hardware/sanguino
|
|
arduino-0023/hardware/tools
|
|
|
|
4. Clone the Sprinter git repository.
|
|
git clone https://github.com/kliment/Sprinter.git
|
|
Optionally, switch to the desired branch
|
|
git branch -a
|
|
git checkout THE_BRANCH_YOU_WANT
|
|
|
|
Firmware compilation and upload
|
|
-------------------------------
|
|
|
|
5. Edit INSTALL_DIR inside Sprinter/Makefile (do not mind the default
|
|
reference to arduino 0022)
|
|
|
|
6. Run make. If everything goes well Sprinter/applet/Sprinter.cpp
|
|
should have been created. You can safely ignore the error message
|
|
mentioning arduino-0023/hardware/arduino/cores/arduino/WString.o
|
|
|
|
7. Connect your Sanguinololu to your computer
|
|
http://reprap.org/wiki/Sanguinololu
|
|
|
|
8. Launch arduino-0023/arduino, open Sprinter/Sprinter.pde
|
|
|
|
9. Go to Tools -> Serial Port, and select the relevant option
|
|
|
|
10. Go to Tools -> Board, select Sanguino
|
|
|
|
11. Go to the Configuration.h file and edit the following lines:
|
|
#define MOTHERBOARD 62
|
|
62 indicates Sanguino 1.2 or superior
|
|
|
|
float axis_steps_per_unit[]
|
|
|
|
set values that match your hardware. For the special cast gears of the
|
|
Bath Masterclass Prusa Mendel, these values are
|
|
float axis_steps_per_unit[] = {91.42857, 91.42857, 3200/1.25,700};
|
|
|
|
also for the mentioned hardware setup
|
|
const bool ENDSTOPS_INVERTING = false; //set to true to invert the logic of the endstops
|
|
// false because the switch SIG signal is linked to the ground
|
|
// "no touch == closed circuit == SIG connects to GND"
|
|
// see http://reprap.org/wiki/Sanguinololu#Endstops
|
|
|
|
12. Click on the "play" button to compile. If everything goes well you
|
|
should see a "Binary sketch size: " message.
|
|
|
|
13. Click on "the arrow going to the right" button to upload (you had
|
|
done steps 7,8,9 before, right ?). If everything goes well you should
|
|
see the message "Done uploading".
|
|
|
|
if GEN7 with 20 Mhz is in use set the Fuses for Bootloader to
|
|
lfuse= 0xF7 hfuse = 0xD4 efuse = FD
|
|
Brownout must be 2,7 V
|
|
|
|
Congratulations, you have just upgraded the firmware of your RepRap !
|
|
|
|
You can use pronterface.py to do some manual verifications by moving
|
|
the printer's tip along the axes and verifying that the physical
|
|
displacements match the ones indicated on the interface.
