Today we're going to talk about power outputs
We have three power output ports here
We have D10, D9 and D8 that can be used for various things such as hotends
Fans and beds they can also be used for a spindle control and a fan
So I'm going to
Go into a little bit of detail in the Marlin firmware to show you how to set it up for the board
That you choose for configuration that'll be next
Okay, we're in the Marlin firmware folder, we're gonna open up Marlin
We're gonna go to the Marlin.Ino file we're gonna open that up
We're gonna select the configuration.h tab. We're then going to search on, "motherboard", now
The initial configuration for the RAMPS in
Marlin is BOARD_RAMPS_14_EFB
now the EFB stands for extruder fan and bed.
so let's go take a look at the, "boards.h"
So in, "board.h", we have the configurations outlined right here at the top ...
I placed D10, D9 and D8
Just for reference purposes normally this would not be there
But our very first configuration that we see as default is EFB
the next one is extruder 0
Or hotend then we have extruder 1 or hotend one, and then a bed
then we have an extruder, fan 0 fan 1, and then we have extruder 0
Extruder 1 or hot and one and then fan and the very last one that we have is spindle
And controller fan, which is SF.
So let me show you what it looks like to do the next four configurations real quick here
so the first one we're gonna do is hotend zero, hotend one and bed
So if we're in Marlin all we have to do on configuration.h is
extruder extruder bed
So now if we go back and we look the next configuration is extruder, fan zero, fan one
That one's going to be EFF
the next configuration that we have is extruder zero
Extruder one which they show is hotend zero hotend one and a fan
so in Marlin that would be EEF
And then the very last configuration is the spindle and controller fan.
So that one would be SF and the next portion of the video
I'll show you a mock-up of what the configurations look like in future videos. I'll show you actually how to configure them
Here's what the mock-up would look like for the board
We have D10, D9 and D8
So the first configuration that we spoke about was the hotend, fan, and bed so for the hotend you're gonna take the
wires for the heating element and those are gonna be put into
Your two connections for D10 and screw them down
then you'll have a thermistor connection which will go on T0
the next portion of this will have a fan
Which goes on D9 and connects to the D9 connections here and
the very last portion is
Going to be a hotend or excuse me a heat bed and
The heat bed is going to connect for the thermistor connector to T1
On D8 You're gonna screw down the wires for the heat bed
The next configuration that we're gonna have is going to be a hotend hotend
So D10 we're gonna do is we did before
D9 we're gonna do the same thing, but we're gonna do it on D9 and we're gonna use T1 for the
Thermistor connection and then we're gonna use the bed
Now the bed's gonna connect to D8 and
The thermistor is going to connect to T2
The next configuration that we're gonna have is
Going to be the hotend which is going to connect like before to D10
with T0 is the connector the next connection that we're gonna have is D9
with a fan connected and
then D8 with the fan connected
Next connection that will have will be similar to the one just before the last one I showed you and that one's gonna connect
for the hotend, hotend so you have D10 for this hotend you have T0
For your thermistor connection now this one's not wired up, but the actual heating element will connect
To D9 just like we did for D10, and then the thermistor connection will connect to T1 and
Then we'll have a fan connected to D8.
And the very last configuration that we're gonna have
Is a spindle controller. Now, this is not the one we're going to be using
But it's a mock up for this case
We're gonna connect that to D10 so the wires will go into the D10 and then be screwed down and
Then we'll have a fan controller which goes on D9 and
We'll connect to the D9 connection right here
