Electronic Wiring on Ramps 1.4 board

5V or12V probe? Careful choose your schematic

  • 12V probe has 1 Dupont 2 pins connector and 1 red wire left over
    • Red wire left over: +12V
    • Black wire: 0V- Ground
    • Red wire in connector: Signal.

 

 

 

 

Here is the wiring diagram to use


  • 5V  probe has only 1 Dupont connector with 3 pins.
    • Brown wire (+5V)
    • Blue wire (0V – GND)
    • Black wire (Signal)

 

  • 5V  probe can be provided with and extender with different colors
    • Red wire (+5V)
    • Black wire (0V – GND)
    • White wire (Signal)

The wiring on the electronic board is similar to the previous version of this probe.

  • The Red wire corresponds to the Brown wire
  • The Black wire corresponds to the Blue Wire
  • The White wire corresponds to the Black wire

Here is the wiring diagram to use


 

 

Schematic for 12V proximity sensor

Electronic wiring on Ramps 1.4

On this 2nd schematic, ou will find a schematic closer to what is provided within the kit. With the induction probe, the hot end fan ad the auxiliary blower fan.

On the induction probe, it is provided with 3 wires. 2  (red and black) are connected to a Dupont 2 pin connector, and 1 (red) left alone with a node here, is the power supply of the probe.

Schematic for 5V proximity sensor

Brachement électronique de la carte Ramps 1.4 avec sonde à inductance 5V

This schematic corresponds to the kits provided after 17th October 2016.

This kit is provided with a 5V proximity sensors. The blue wire is the ground wire. The black wire is the signal wire and the brown wire is the +5V powe wire.

If your probe is not provided with a 3pin black connector, please look at the other schematics.

A Y shape wire extender is also provided. It’s directly connected to the 12V power output of the Ramps board and will help you to connect the hot end fan power supply to the +12V. It will also be used to connect the 80mm 12V fan dedicated to cool down your electronics.

 

You should be able to recognize the other components now. The wire’s color on the stepper motors are only for information, the one provided might have a completely different set of colors. The one on the power terminals are real colors with the red wire corresponding to +12V and the black wire to the ground wire (0V)

 


Ramps 1.4 Schematic

Ramps 1.4 Schematic

For information purpose here is the official schematic of the Ramps 1.4 board. It is the same you will find on the official reprap wiki  .

This schematic give you more data on all the pin out and also on the optional headers.

 

 

A word about the Big green power terminal

Ramps 1.4 power terminalsYou need to understand that the Green power connector on the left of the schematic picture is a Plug connector,

Meaning that the big part with the terminals can be removed from it’s base.

The picture here shows the 2 different parts:

  • On the left the terminal part that can be removed/unplugged
  • On the middle the fixed part, soldered on the ramps board
  • On the right side, the 2 parts attached together.

 


 

As visual support here is a picture of the electronic board free from any cables.

If you want compare directly with the previous schematic, you will need to make a 180° rotation as the power terminals are on the right on this picture and on the left on the previous schematic
