Hello new Infonaut, welcome or welcome to a new installment of your YouTube channel Infoductiva
this time I bring you a video in which I will talk about the 3D printer and we will learn how to calibrate the heaters of both the Extruder
like from the hot bed ...
interesting, right?
We started ... well first
We will have to access this page, which is the Pronterface page
I leave the link in the description of this video ... as you see
It allows several things, what we are going to do is basically use the control that has
to send commands to GCode so that you can calibrate
both the heater of the Extruder and
the heater of the hot bed and thus be able to define correctly
some PID values
that are suitable inside our printer and thus be able to get
better fit and better performance
of our 3D printer
Well, first of all clarify that the PID is an algorithm
let's say ... let's say it ... it's like a function ... okay?
and the meaning of each of those acronyms
It would be Proportional, Integral
and Derivative
and to get these three data
... the appropriate ones
depending on the season, because this ... let's see, I want to clarify it ... I for example have a 3D printer
and in the room where I have it
does not do the same temperature when we are for example in winter than when we are in summer
agree? yes in that room
you work with air conditioning, which is not recommended
or work with a heater
You would have to do this calibration every time there is a drastic change in the temperature of the room, okay? yes
your printer is logically encapsulated this calibration will not have to do it
at each change of season but every so often depending on the variation that may exist
all right? ... what is the calibration for?
let's see ... when we order
make an impression with for example 220ºC
the heater of the extruder takes a while to reach that temperature ...
if we have it properly calibrated it will take less and once the temperature is reached there will be no great oscillation in it, so our impression will be
much better ... it will have a higher quality ... okay? since there will not be
no variation in temperature
of the plastic at the time of injecting it
and if we talk about the hot bed, the same ...
if we order an impression with PLA in which case
we want the warm bed to reach 60ºC logically if we do not have it properly calibrated
it will take a long time or it will not even reach that temperature
and even reaching the temperature we will notice that there is an oscillation of about 5ºC or 10ºC ... well? to avoid this is done
this calibration that we are going to see today here ... the first thing that we will have to do is come to this page ... come to downloads ...
and good in principle is a repository
Git that can be linked
agree? but we have binaries here for both MAC and Windows computers, according? if you are working on a Linux
you directly make a clone of the Git repositories and that's it and you work with the
in my case I'm on a Windows system so I'm going to click here
this as you see leads us to
the program in several versions Printrun for Mac and then for Windows
and how do you see an obsolete folder, one of the oldest, according?
if we look inside those that are MAC gives us different dates so that
we would choose to select
the most recent one that would be on November 18 of last year of 2017 and if we are as is my case on Windows
we will do the same but how do you see here we have
the last one is Printrun for windows
and yes we want the Slic3r that we will talk about it later on as we would have to choose this which is the last of the 2015 febero well?
I'm going to click here to download it
this Printrun
win November 18, 2017
we wait for it to be downloaded ...
it is already, we have it here downloaded so that the folder downloads
this compressed package has been generated
that when you download it, it will generate
a folder
with the same name ... Printrun win November 18, 2017
yes we enter inside as you see here we have
on the one hand
its folders, its structure and on the other hand
the Pronterface program itself which is what we have
to execute now well ... a clarification before
continue with the process ...
we will have to execute this application
having our computer
connected to our printer
3D according? then before we start using the program we will have to
make sure to turn on our 3D printer and of course it is very convenient
configure the program before carrying out the commands that we will see below ... okay?
I'm already with the program open
with the connected printer
and just turned on
agree?
in principle what I'm going to do
is here in this menu that appears in the upper left as you see let me select a port that in this case has already detected
it's COM3 so I'm going to give it to connect
the speed is too high
so I'm going to go down to 115200bps
and I'll give it back to connect ... now if ...
very well, that's the proper speed, as you see in the printer not see absolutely no change
in your window
and now what we are going to do fundamentally
is to calculate the parameters of the PID
for the heater of our Extruder
For that
we are going to
center down here on the right
where do you see
here apart ... I can mention you ... apart from putting any code or instruction
in GCode, here on the left we can manipulate our printer and make it move
but it's not the goal of this video, this would be the heater and this one down here would be
the one with the hot bed that are the two that interest us ... then ...
In principle when we talk about the heater of the extruder we have to take into account for what we are going to calibrate ...
I will calibrate it for ABS in this case so that what
I will do is directly give you an instruction that will do a number of times
the cycle of reaching the temperature that I tell you and that is going to return me or tell me what the PID is
In other words, the different values that I would have to apply in electronics, right? then in
principle what I'm going to do is clarify that if we were doing this for PLA
what we would do would be to use another instruction that would be
M106
M106 F255 and when I say this what I would do would be turn on
the material fan
from our extruder ... if you try it and you give it
you can see how the fan has been put into operation ...
agree?
good as this case is not the one that matters to us I'm going to give a Reset
It has been turned off right now
everything, that is, the fan is no longer running
you can see it here, I think you can see that the fan is totally still ...
all right?
so now we are going to focus
in making that temperature curve for a number of cycles
so that the command itself to be able to make the calculation of the PID parameters of the extruder would be ... always in capital letters remember ...
the instruction would be M303 space
I repeat M303 space
next we are going to talk about the extruder, as my printer only has one would be the E0
agree? If you had more than one extruder because this would be the first, E1 would be the second
and so on ...
next space S220
and finally space C8 ... let's see ... I'll clarify what this means ... M303
M303 is the command or instruction that allows us to calculate the PID
then a space, the first parameter that asks us would be
to which extruder or what heater are we going to do it, in this case
is the first extruder ie E0
next a space and you see that I have put S220 that is to say that is the temperature
the S parameter represents that what comes next is the temperature at which you want to make the Test ... the calibration
I've put 220 because I'm talking about the extruder and it's the temperature where I think there's
to start printing or extruding ABS, if you were doing a test
or a calibration in PLA instead of 220 we could put perfectly 200
and finally space C8 ... C indicates the number of cycles that it is going to do, so, the first thing I do is
press Enter
doing it as you can observe
start making a
Autotune start
this is going to take some time
you can see on the screen that although it seems that
the temperature that needs to be reached is 0ºC, even if that puts 0º you see that the temperature is rising remember that I have put S220
okay?
You are also seeing in the window
on the left as the temperature goes up
all right?
there is practically no difference
and this would be to say it in some way the first cycle
of the test, as I told you to do it 8 times so let's say that
will get a temperature first time
will induce it in a second way to get closer, not go over, etc. and this what he is doing is calibrating our
extruder ... our heater
As we are doing precisely to the heater of the extruder once it is well calibrated what we are going to get is to have a
greater fluidity when it comes to extruding plastic, in this case I put 220 because I'm doing
to calibrate this printer
for ABS plastic
well, we are already 210º, remember that we have put 220º
look at how he's going through a few degrees
all this is part of the calculation that takes place
this is very important to do with the filament outside, that is, do not have any filament in the throat
focus on seeing the data we have
on the left
as you see it is going down, we are already below and we are in 215º forgiveness ... 216º
and then it starts to rise again, so look, it's stayed at 3º
below the temperature and then it is passed but it is no longer passed
as much as it has happened in the first cycle
all right?
This is very important to do to your printer before you start working with it for the first time
and I recommend that there are temperature variations in the cabin where you have your printer or in my case
But of course, if I had it encapsulated it would not be so much fluctuation ... what I mean is that in winter
When the winter starts I do a calibration or when we are already in winter and when we say that we left the spring I do another calibration
with which I always make sure that the temperature is reached quickly
and optimal
as you see, data is appearing
of autotune
anyway, we're just going to focus on the data
to tell us when the process is finished
only 5ºC over
and it's coming down again
let's say it's like an adjustment or an adjustment through what's called PID, right?
Proportional, Integral and Derivative, remember
and by this calibration we make sure of that, that when the electronics receives a
concrete temperature really is that temperature
or when you send him a warming data you already know how he reacts ...
We are adjusting the heater of the extruder ... very important ...
as you see now it's 4ºC above ... 3ºC ... it's already going down
Remember that if you have a printer for each plastic because logically it is very important
do this for each of the different plastics
what do you have
how you see, look, you are already giving us some data
Kp, Ki and Kd ... that we can observe here
but as you see it's not over yet ... it's still going through cycles
I'm interested ... I'm not shortening the video because I'm interested to see how it's fluctuating to me
as we say is closing that fork on the temperature that we are asking
and the data that is being offered to us
on the right
logically they are the adjustment to get
precisely that reaction
both the heater and the thermistor because here come into play both, both the heater and the one that sends what is the temperature
to electronics to know if you have to keep going up or down
or if you have to turn off before, okay? not to exceed it
as you see, each time is more adjusted
since this is going to take time
I'm thinking about doing the second part of the video in a separate video, okay? so that I can focus exclusively
in the hot bed ...
as you see we are in the temperature ... it is already, we would already have it, it is over ... I can tell you here to disconnect
agree? to stop
and then we can focus
in the data that we have obtained here on the right
As you can see we focus on the last ... in the last sequence of data that would be this
just the one that appears above info
the Autotune PID has been completed
Place the values of Kp, Ki and Kd in the constant of the configuration
Configuration.ho in your EEPROM of your
printer ... let's see ...
let's aim in the first place
these 3 data ... okay? this is important to have it targeted
KP is giving me
Of course, each one of us will give us different values, according?
Kp is giving me 7.68
Ki is giving me 0.34
and Kd
finally he is giving me 42.90
Well, let's see, how do we transfer it directly?
to
our printer? let's see, the first thing we have to do is come to the panel of our printer
in the menu you can see that in the first menu there are many options but there is a very important one called configuration
when entering here inside as you see gives us some general data
of acceleration, of the Feedrate
of extrusion and to save
the configuration, well ...
let's go to what interests us ... what interests us is to first enter General
and how you see here gives us baud, speed ...
all right?
how do you see this is the speed at which we should have put the program
all right?
that's why that happened to us
acceleration
Feedrate that would be the movement
of the axes, this is where we set it
extruder would be the one that interests us so that as you see here we have
speed options
of acceleration
of waiting, of control and here it is ...
we have PID on one side P, I and finally D ... well let's review
in P as you see me
is telling me in this up here
he is saying 11 when in fact he told me Kp 7.68
so here what we would do would be to lower
you see that it does not allow me to put 68
so
taking into account that I can round it up because I'm going to put
which is ... it can not be 7.68 so it's going to be 7.70 in my case ... okay?
then the second data that is I ... in Ki he told me that it is 0.34 so we are going to press and we will lower it
until you get to the nearest data that in this case is going to be exact
and finally we select
D's
and instead of 42.80 is 42.90 ... we hit
and we will lower it to 40
It is done
sorry 90 ... it's not 40 ... it's 90
there ... 42.90
we press and we would have it
it would be simply to go back
and give on the option
from Store to EEPROM ... I will press
how do you see it says it has been
restored the configuration ... that has been configured
so yes we go back to the extruder
we can check
that in the PID data
as you see we have 7.70, 0.34 and 42.90
that's it, we have already finished configuring the PID of our extruder of our 3D printer
with this we make sure we have a very fine adjustment
at the time of printing, in this case in ABS plastic but with changing temperatures
you could calibrate for PLA or for any other
you would not have any problem so good
I hope it has been helpful, if you liked it, give it a Like and share it and we'll see you in the
next video in which I will focus on doing the same for the warm bed
