18.8 To connect step motor. First cut off some heat shrink tube (one piece for one connec-tion) it means we need at least four pieces for one motor. Then slip each piece on each color of the wire.

18.9 Now twist wires together from motor and wire connector (twist the same color of the wire together).

Electronics Calibration

249

19.1 Arduino Mega 2560 system does not have a preloaded firmware. Go to the page:

http://arduino.cc/en/Main/Software

Download software called Arduino 1.0.5 then connect via USB RAMPS electronics.To install needed drivers we need to proceed with the following steps:

1. Plug in your board and wait for Windows to begin its driver installation process. After a few moments, the process will fail, despite its best efforts.

2. Click on the Start Menu, and open up the Control Panel.

3. While in the Control Panel, navigate to System and Security. Next, click on System. Once the System window is up, open the Device Manager.

4. Look under Ports (COM & LPT). You should see an open port named Arduino UNO (COMxx).

5. Right click on the Arduino UNO (COmxx) port and choose the Update Driver Software option.

6. Next, choose the Browse my computer for Driver software option.

7. Finally, navigate to and select the driver file named arduino.inf, located in the Drivers folder of the Arduino Software download (not the FTDI USB Drivers sub-directory). If you are using an old version of the IDE (1.0.3 or older), choose the Unos driver file named Arduino UNO.inf.

8. Windows will finish up the driver installation from there.

ELECTRONICS CALIBRATION

19.2 After successful installation, open the software Arduino, by default it will open blank sketch. Now we need to download pre-configured firmware from this site:

http://gadgets3d.com/firmware/RRG3D.zip

RAMPS 1.4 CS electronics also works with otherfirmware variations, such as: Sprinter, Teacup, sjfw, Sailfish.Preferred firmware: Marlin.

251

115

19


19.3 From the menu, choose File> Open, and then look forfirmware in downloads folder. Browse to the folder and look for file Marlin for Prusa i3 with extensions .ino.

252

116

253 254

19.4 Now select the menu Tools> Board - Arduino Mega 2560 or Mega ADK and then Tools> Serial port - COM7 (number can bediffer).


117

19

19.5 Next step is to upload the firmware to electronics by clicking button with arrow signed Load.

255


118

19

19.6 Sketch will be compiled and loaded into the Arduino, during this operation, the LED should blink. The program displays information about the correct code is loaded. After uploading the firmware we are almost ready to go. Now you need to calibrate the stepper motor drivers.

Caution! Potentiometer VREF for stepper motor drivers should be turned maximum anti-clockwise before connecting power.

256 257


119

19

19.7 Connect the power supply to the board like shown on circuit diagram (picture 248). For this task you need a multimeter or a voltmeter and ceramic flat screwdriver.

19.8 Now applying the measuring tip to the VREF (plus) and GND (ground) check voltage difference. Calibrate drivers by increasing the voltage on the potentiometer VREF, to do this you need ceramic screwdriver.

258 259

260 261


120

262

19.9 In order to fully calibrate the electronics you need to repeat previous step for all drivers.

Properly calibrated stepper motor driver:

for motor axes X, Y, Z - 0.9 Vthe extruder motor - 0.9 - 1.1 V

Disconnect the USB cable and power from electronics.

Importing Slic3r profiles

20.1 Go to website:

http://slic3r.org/ and download Slic3r software for your operating platform (windows / iOS / linux).

Then download our Slic3r Config:

www.gadgets3d.com/slic3r/RRG3D.zip

and unpack it (windows x86 & x64).

IMPORTING SLIC3R PROFILES
