First :
• Install the Arduino soware (1.0.6 version or lower). You can download it from our website or the ocial Arduino’s website.
Aer that, the RAMPS board must be connected on the Arduino board.
• Connect USB (do not connect the power supply).
• Check if the board is identied by your computer. You can to push on « Windows + Pause » -or go to your compute setup-, and on « Device manager »
on the le. e Arduino Mega 2560 board must appeared in the device list.
System panel of Windows Device manager
Read the COM port of your Arduino board (Arduino Mega 2560)
Driver and the rmware installation
Note : If Windows 8 or higher is installed on your PC, you should deactivated automatic control of unsigned drivers. It’s possible to nd process about
this on the web.
If it is not regognized, please install drivers manually by doing a right-click on it. Arduino’s drivers is in the Arduino «drivers» folder.

Connect the RAMPS board to the power supply 12v and respect
polarity.
Before to begin this tutorial, you have to get:
• e electronic and mechanic parts (see the assembly instruc-
tions);
• e board need to be identied by your computer;
• e rmware is download.
First we are going to settle the host soware (Repetier host) com-
munication.

Check the message «idle » at the Bottom of the page.
If you have waiting commands, it means that you have connection problem with your printer.
Check the COM port and push on Reset button or reconnect the USB wiring.

Conguration and preset
Let start to a material checking on your machine.
Manual moving of axis
Push your carriage X and Y to the center of their axis, -if you feel resistance don’t force! -, You only need to unlocking your motors :

For Z axis, move up the extruder for at least 20 mm above the PCB heatbed by turning the two couplers at the same time.
Be sure that axis X stay horizontal to not damage plastic piece.
Now you are ready to move safely.

To know if your endstop is functional, connect them and check that the red LED switch on when you do a contact.

Press the X homing and check the X carriage stop to move aer touching the endstop X.
If there is a problem you can press on the emergency stop button to stop motors.
Repeat the operation for Y axis.
For Z axis, we will explain the prober in the h parts («using of the paper»).

Disconnect Repetier Host and all power sources (power supply 12V and
USB).en invert your motor plug on the RAMPS card. Reconnect your
machine.
Repeat the operation for Y and Z axis. For Z axis the positive direction
means a vertical rise.
Activate support fan
If a fan does not work, check the polarity.
Invert motor’s direction
e extruder has two fans. One cool the extruder body and other one
cool the piece. e rst is above is activate when you connect the 12V
supply. e second will be activated automatically or through the manual
control interface (see below).

Launch the heating of the cartridge heater: Extrusion
Check if the motor turn in the good direction (do not set up the
lament). Use manual commandsto extrude 10 mm:

Note : extruder’s temperature will progressively increase to the targe-

If it is necessary, invert the direction connection of the motor connector on
RAMPS board.
Launch the heating according to the sort of plastic lament:
• For PLA: from 200° to 210° and 50° for the PCB heatbed (Cover the plate
with Polyimide for a better adhesion)
• For ABS: from 230° to 250° and 90° for the PCB heatbed, (spread ABS juice*,
on the plate cover of polyimide, with a brush to have a better adhesion)
* ABS juice: Dissolve ABS lament in some acetone to obtain a liquid mixture.
For instance : In a glass, pour 10 cl of acetone and add 10cm of ABS lament,
thicken with more lament if the adhesion is not sucient.
Insert plastic lament 1.75 mm in the extruder by pushing on the Extrudeur Idler
(xed on a spring) to free access to the lament.
When you have reach the temperature, use manual command to extrude.
Check that your hotend have no leak, if it is, it means that you had not well build or tighten your extruder.
Check also that the drive wheel well train the lament continuously and without slippage. In a rst time, you can re-tighten the spring.
Cut the lament extremely beveled to

e inductive sensor will allow you to automatically palpate 4 calibration points to correct mounting imperfections.
is only detects metals (detection ~ 1mm for non-ferrous metals (aluminum, ...) and ~ 3mm for ferrous metals (steel, cast iron, ...).
Caution: use of a glass plate is prohibited with the use of the bed of aluminum.
Using Z Sensor
Position the inductive sensor slightly above the nozzle.

Step 2 : checking sensor operation
View the feedback (logs) : Position a metal object in your sensor and type «M119» in the command
prompt of «manual control» tab.
Type of response expected in the logs:
Reporting endstop status
x_min: open
x_max: open
y_min: open
y_max: open
z_min: TRIGGERED
z_max: open
is command allow you to check operation of printer’s sensors.
Note: try the M119 command when you do not have a metal part to recover
the «open» mention in z_min.
If you do not have feedback of your inductive sensor, check the orientation of
the sensor connector and a possible false contact on RAMPS card + adapter
board + inductive sensor.
Note: on some sensor model, the indicator light remains on power
supply and not sign detection.

To reduce the correction of the auto-leveling, it is highly advisable to balance the height dierence between the two Z motors.
Step 2: Balancing Z motors
With the power supply o, push the X carriage to the endstop and turn the coupler until your heating nozzle touches the bed:

In manual control, make some upward and downward movement. If you nd that motors struggle to move, adjust the potentiometer of the Z
axis stepstick so that the movements are uid and without missteps.
