This is the Arduino Mega 2560
This is the RAMPS 1.4
This is what you're going to use for a 3d printer to connect it
You're going to connect to the female ports
with the male ports on the bottom of the ramps
To do that it is kind of simple
going to line up your pins and use a little bit of thumb pressure
To make sure all it is mounted correctly
When you want to load
software on your
Arduino you're gonna use this, end of the USB cable and
connect it right
here
Then you are going use the other end on your computer, on your USB port.
Let me describe the a couple of
things on the board for you here
we have our two extruders
We have E1 and E0
This is the port for the motor for E1 here is the E0
Then we have our end stops from here
To here, this is X-Min
this is Y-Min or excuse me this is X-Max this is Y-Min
This is Y-Max
This is Z-Min and this is Z-Max
Then you have your
thermistor pins here there is three sets
the first set being these is ... it's a
thermistor 0
thermistor one
thermistor two
normally you would use thermistor zero
for your extruder to monitor the temperature the second set is usually used for your print bed
and the third set is extra that you can use for other things sometimes
Then you have your
stepper for
your Z-Axis
there are two ports for your motors
Then you have your Y which has one port for your motor and then you have your X which has one port for your motor
over here you have
two pins that you use for your fan
The side being positive this side being negative
you, have your PSU port this is used for an on/off switch i believe and there are three pins here
then you have your power reset pin and
Then you have your
Servo pins
this is an auxiliary set of pins this is auxiliary 1 this is auxiliary 2 , this is auxiliary 3, This is auxiliary 4
over here
we have our power pins that we use for our extruder which would be D-10
this is the negative side this is the positive side
then you can use the next set of pins for either fans
or you can use them for your heat bed
that will go into a little bit later this is the actual power supply
that connects to your port to power everything
this power supply I'm going to show you with examples using a 12 volt power supply
it can do 24 volt, but that is more advanced
We also have some pins that I wanted to show you these are your I2C pins
And you also have SPI pins on auxiliary 3
Okay if the Arduino over here with the RAMPS on it
we have the connector that we are going connect to the
computer now you should hear a beep when it connects if you do not it might mean that your
driver software is not loaded this is a windows-based machine
so you get a blinking light saying that it is actually connected
Okay, for the first thing that we are going do we are going go to our marlin folder
Inside the Marlin folder the quickest way to get to your marlin
File start is hit the letter, 'm', then you want to click on the Marlin.ino?
As soon as it opens
What we're going to do is figure out a couple of simple things first being our USB connection
So here's what we're going, to do we're going, to go over to tools
Go to ports
It appears to be on COM 3, so we check that off
Now, we need to pick the correct device in this case I already had two chosen
But if you need to choose it you can choose it through here and
Then the subtype which is the 2560
Now, see how we're not doing much with this particular configuration all i'm trying to show you how to do is load it
To load the firmware
You are going hit the upload button and what will occur is it is going to compile first to make sure there is no errors and
Then it is going upload, to the device so watch the
taskbar in the middle of the screen
and right now what it is doing is it is compiling the solution file
And now it is uploading it to the Arduino MEGA 2560
