If you are doing oven or hot plate method, now is the time apply heat (add links here). If you used a solder iron, you have probably already soldered all these components.
Make sure to inspect the SMT soldering at this point since it will be harder to rework after the headers are on top.
Solder 1 1x6, 6 1x4, and 7 2x3 pin headers on top of the board. The long post should be standing up to take a connector. Solder one leg on each one to tack them into place. Then re-heat the joint and push on the component until it is perfectly situated. Then you'll want to solder the rest of the leads. You will get burnt if you touch the other side of the pin you are soldering.
If you want to use the extra pin outputs, now is the time to solder on the rest of the headers.
Place the female headers for the stepper drivers on top of the board. You can use the 1x8 and 1x6 pin headers to jig them straight. Turn the board over and solder these pins.
D1, D2 - 二极管
These must be placed in the proper orientation. The band on the diode must be turned the same way as the mark on the board.
Definitely solder D2 in. D2, F1, and F2 are shown installed here.
D1 should only be installed if the 5A rail is powered by 12V. It can be omitted and the Arduino will be powered from USB. You will want D1 installed if you add components to print without a PC. To reiterate, D1 MUST be omitted if you are powering the 5A rail by more than 12V, or the power is not absolutely clean, otherwise you may damage your ramps.
F1 - MFR500 保险丝
This is the smaller yellow fuse. This can be placed in any orientation. When soldering the fuses it is best to use a piece of 3mm filament or something similar to keep the ceramic coating on the pins from blocking proper solder along the through hole.
Since the fuses are the tallest parts, it is simpler and more convenient to solder them last. From this point on, solder the rest of the RAMPS in order of bottom pins, reset switch, terminals, mosfets and then fuses.
F2 - MFR1100 保险丝
This is the larger yellow fuse. This can be placed in any orientation.
Q1, Q2, Q3 - 场效应管
These must be orientated as in the picture. The tall heat sink part of the mosfet needs to be turned the same as the mark on the board.
This must be oriented where the wire holes are turned towards the edge of the board. Solder a pin on each end and make sure the component is flat on the board and solder the middle pins.
This can only be oriented in one direction.
This can only be oriented in one direction.

- Cut the pin headers to 8 pins long so that they fit each side of the stepper driver.
- Insert the pin headers into the sockets on RAMPS
- Fit the stepper drivers onto the pin headers and solder. Only heat each pin for a few seconds at time to avoid damage to the socket.
- Cut the 26awg 3 conductor cable into 3 length.
- Note: you may want until you've built your machine to cut the cables to the perfect length.
- crimp and solder a female connector to the ends of each wire. (solder not necessary with proper crimp tools)
- use the 2.54mm 1x3 housing.
- Connect at least the minimum endstops.
- 将RAMPS上的S (top row, labelled to the left)连接到开关的NC端.
Note: The latest firmware such as Marlin seems to use NO as the default pin on the switch. Otherwise you may need to invert the endstops in the firmware. You can use M119 to check your endstops status.
Put the connectors on the motor wires
- solder a female connector to the ends of each wire.
- use the 2.54mm 1x3 housing.
- Shown is the type used for servos in RC projects. See Stepper Motors for info on motors.
Use a 2 pin 0.1" connector to terminate the thermistor wires.
- Connect the cable so the 2 wires go to T0
- Connect the 2 heater wires to D10 (E0H on older boards) and the + connection above it.
- If changing to an unverified firmware it is best to verify heater circuit function with a meter before connecting heater to prevent damage to the extruder.
This section assumes you are using Pololu, but there are other options. Insert two 1x8 pin headers into the board. If you bought a kit with one 16 pin header, simply cut it so that you have two 1x8. Make sure that the side with the labels has the long ends of the posts, and the side you want to solder is the side with the heat sink. Doing this backwards will cause you not to see the labels and will most likely not fit. Remember to apply a heat-sink to the largest chip on the back.
步进电机驱动器上的电位器实现限流功能。Turn it all the way down (counter clock wise) and back up 25%. Be careful to not force the trimpot, it is delicate. You will need to fine tune the current limit later. Note that it is allways giving the motors that much power, even when not moving, so if your stepper motor drivers are getting hot, you may want to turn it down slightly.
Connect the minimum endstops for X,Y, and Z
连接步进电机 (Do not disconnect or connect motors while powered; if the connection is loose, this will cause the motors to spazz and possibly kill your stepper driver.)
你可能需要这个 代码 在刷固件前检查各个电子器件。
安装固件 (见下面). 刷固件也可在不加载12V电源的情况下进行。
给RAMPS接线很容易。 将挤出头供电线连接到D10, 将热敏电阻的线连接到中部右侧的T0排针，接上步进电机和限位器。从左 到右依次连接步进电机的 红、蓝、绿和黑或红、绿、黄、蓝线到Pololus边上的排针。当你连接限位开关时注意连接标签是否正确(如果你采用3个限位开关，将其连接到MIN (-)插槽)。
Reversing +/- or otherwise incorrectly connecting power can destroy your electronics and cause fire hazard.
Incorrectly inserting stepper drivers will destroy your electronics and cause a fire risk. Always make sure power and USB is disconnected when removing or adjusting stepper drivers. Always make sure to insert drivers in correct orientation and in the socket correctly.
The endstop pins are Signal - GND - VCC, instead of the VCC - Sig - GND like the rest of RepRaps boards. Make sure to wire them correctly. This is done to allow squeezing fatter traces on the printable board.
Connect your 12V power supply to the RAMPS shield. Reversing +/- or otherwise incorrectly connecting power can destroy your electronics and cause fire hazard.
The bottom pair of connectors marked 5A power the stepper drivers and Extruder heater/fan (D9, D10). The source should be rated a minimum of 5A.
The pair of connectors above marked 11A power a Heated Bed, or other output (D8). The source should be rated a minimum 11A (if both power rails are connected to the same supply it should have a minimum rating of 16A).
The barrel connector, on the Arduino MEGA, will NOT power RAMPS and will not provide power to the stepper motors, heated bed, etc.
The power connector plug may not be obviously labeled, looking at the power connection the positive is on the left and the negative is on the right of the plug.
RAMPS is quite happy with the 12 V line from PCPowerSupply. Or you can hack up a 12V laptop power supply, or other 12 V "wall wart" power supply. Be sure that the power can output 5A or greater. Additional 11A may be needed for heated bed support.
See Connecting power above.
The 3 pins next to the reset switch are meant to optionally connect to your PSU.
The PS_ON pin is intended to switch your power supply on and off. Many firmwares support pulling this pin low with M80 command to turn the power supply on, and M81 to turn it off. This behavior is desired for ATX power supplies and can be modified in firmware to support 5V high power supplies like those borrowed from an Xbox.
Without D1 installed, or when the 12VIN is not connected, the Arduino gets its power from USB. If you want your kit powered without USB connected you need to solder in D1 OR connect VCC to your PSU.
The VCC pin can be connected to your ATX's 5Vsb to continuously power the Arduino from your ATX power supply. You will want to make sure that D1 is not installed or cut out. The Arduino is not designed to be powered directly on the VCC rail and the VIN pin at the same time.
The 5V pin in that connector on RAMPS only supplies the 5V to the auxiliary servo connectors. It is designed so that you can jumper it to the VCC pin and use the Arduino's power supply to supply 5V for extra servos if you are only powered from USB or 5V. Since there is not a lot of extra power from the Arduino's power supply you can connect it directly to your 5V power supply if you have one. You can also leave this pin not connected if you have no plan to add extra servos.
Power Supply without diode
The 1N4004 diode connects the RAMPS input voltage to the MEGA. If your board does not have this diode soldered in, you can safely input as much as 35V. (The pololus can do up to 35V)
Power Supply with diode
If your board has a 1N4004 diode soldered in, do not apply more than 12 V to it. Original flavor Arduino Mega are rated to 12 V input. While Arduino Mega 2560 can take 20 V, it is not recommended.
Firmware and Pin Assignments
RAMPS 1.4 uses the same pin definitions as 1.3.
You will need the Arduino software at http://www.arduino.cc/en/Main/Software to upload the firmware to Arduino Mega. Arduino MEGA 2560 Rev3 requires Arduino software version 0023.
Working preconfigured sprinter firmware can be downloaded at http://ultimachine.com/sites/default/files/UltiMachineRAMPS1-4Sprinter.zip . Mechanical is in the folder ending with ME, optical endstop firmware is in the folder ending in OE.
Others (Need pins set in Firmware as below):
- mechanical endstops (now the default ultimachine.com option) require #define OPTO_PULLUPS_INTERNAL 1 to be added to configuration.h if not there by default.
Here are the pin definitions for this board.
