this is an E3D hotend, basically your material is melted when it goes down
through the tube into here and then that is where your material is deposited
from on to the surface some interesting things we have a resistor that we have
locked in here that will allow it not to be removed and then we also have a
thermistor which is a little glass filled bead that measures how quickly
current travels through at different heats so what we are going do is we are
going hook it up on the ramps now here is the thermistor wire you do not have to
worry about positive and negative to do this you are going hook it to the
thermistor block and it is going to go into the very first two pins and you just
plug it in like so now for the actual thermistor you are going to connect it to D10, which is over here now positive and negative do not matter
so you are going slide in the first one
tie it down just slide in the next one and tie it down and that is all you have
to do for the install portion for the driver portion I'll show you that in
just a second or the firmware portion pardon me so you are going connect your
USB wait for the beep and then we are going try it up okay
within the Marlin folder we are going find the Marlin solution file we are
going open that up
and now we are going go and check see that we are connected with the correct
port and it looks like we are good on the board we are going to go to the
configuration tab we are going scroll down now we already have the port set to
the default so we generally do not need to change these the baud rates good.
Now motherboard we are using the ramps 1.4 so we are using an extruder a fan and this
is a designation for a bed right here for the B but currently we are not using
that so we are going ignore that we are going scroll down a little further we
only have one extruder in this case do not have to worry about setting a
single nozzle because that is for multiple print heads or excuse me
multiple ports for a single printhead
so we are getting down to where we need to do some settings here okay thermal
settings this is a list of thermistors that we could possibly use now in the
case that we are using it is going to be this one right here so when we get down
to the bottom we have to set it so we have four different or excuse me five
different temperature settings and bed in this case we're only using the first
one so we are going mark it as eight zero I believe is not used now these are
dummy values we are not going to use those at the moment I'm not going worry
about all these complex settings here is the minimum temperature that we are going
use it is going be five degrees Celsius all the other bed settings do not really
matter or thermistor settings now we are at max temp seeing how we are using just
PLA one because it is safer to because it is easier to use we are going change
this to a max value of 200 degrees Celsius now these are specialized
settings to calibrate to your actual printhead there is a million different
videos on how to set these up so I'm going ignore that for now so there is one
less setting I want to show you
okay if they are multi-terminal run away right now they are uncommented I'm not
going to tell you to comment these because I believe it will make running
safer for you always stay in the room while you are printing or nearby but
these will protect you if your temperature runs away and will shut down
the printer so what we are going to do now is we are going to compile and upload
okay we are going to connect the power to the main board this goes to the 12 volt
power supply and then we are going to plug it in now normally this is going be
inside a printer so I have it propped up right now on iron bars to keep it safe
and I'll show you in Pronterface how to actually test it okay we are going open
up Pronterface we are going connect to the RAMPS now currently our temperature
appears to be it looks like about 8 degrees Celsius and our PLA default
right now is set to 185 degrees Celsius this may vary you can always go to
settings options and set the defaults in here so to turn it on we are going keep
an eye on this to see what the temperature is right now it says eight
point five eight degrees Celsius and we are going see if it actually works so
it looks like the power supply has got some stress on it because the fans gone
on and it looks like temperatures beginning to rise so it looks like it is
going work when you test this on your own make sure that you will have it in a
safe place and you are keeping an eye on it and for now we're just going turn it
off because we have already gone up 50 degrees Celsius and if you liked my
