today I'm going to talk to you about the MKS Gen L, but what I'm gonna do is
something a little different I'm gonna talk about how the Marlin firmware
relates to the actual board so the first thing I'm gonna start with is opening up
the pins for the MKS Gen L this can be found online but I can also post a link
to help you find it so inside here as you can see over here it says D37 D17
D23 D27 these are pins that are associated with digital pins some unique
things are where it says like A13 A14 A15 those are analog pins and then
where you see 5v and GND that's five volts and ground and then over here for
our extruders extruder number two which is listed as E1 it says D7 that's
digital pin 7 and then the first extruder which would be D10 so now that
we have an idea of what this looks like and close out of this and I'm gonna open
up the Marlin folder for the bug-fix 1.1.9 bug-fix inside here we're gonna
search on pins and what we're looking for is pins MKS Gen L and we're gonna
look inside here for a second inside here we have a definition of what the
board name is which is n KS Gen L then we also have a MOSFET D7 what
that means is digital pin 7 and then we have two unique settings for chip select
these are used usually for something like a TMC 2130 extruder and the chip
select is the actual way to specify the individual board to communicate with so
it can only communicate with one board at a time
so it's assigned a digital pin which a wire runs to the board and allows it to
communicate right here we have something unique
it says, '#include "pins_RAMPS.h"' ', what that's saying is take the
"pins_RAMPS.h", file and concatenate it together with this one or
appended to this one so what we want to do is actually look inside this file
because that's where the remainder of our pins can be found and then one last
thing I haven't spoken about this actually is a conditional setup for
making sure that we don't exceed the number of extruders so we might have to
manipulate this in the future we want to add a third extruder so I'm gonna close
out of this in a second and I'm gonna show you what in, "boards.h", our board
looks like it's, "BOARD_MKS_GEN_L", that's the actual name
of our motherboard and then I'm going to show you the pins folder inside the pins
folder we have a specification for all the pin values that we are using in the
first file that I showed you when we opened up for the pins for the MKS Gen L
as you can see there's something unique here where it's saying pin 7 11 6 5 & 4
4 servos we only have four servos this is talking about the older RAMPS board
which is RAMPS_13 or 13 then down below we have a bunch of
information about our limiting switches limiting switches our end stops and then
they talk about the axes and we have a chip select set for each one which
I'll go into in the future with a stepper and explain how that works so
I'm gonna close out of this and I'm going to open up the Marlin firmware
solution file for the IDE
okay for the IDE there's several different configuration dot files for
header files, "configuration.h", is where we'll do about 85 to 90% of our
configurations, "CONFIGURATION_ADV.H" or advanced configuration.h is
where the remainder is so I'm going to only talk about, "configuration.h", in this
tutorial so moving through it really quick you can see that there's a version
number that they've set up or the actual file they talk about who developed it
and what information is relevant to it down here they talked about getting
started this is useful links that you can go and look up information about the
Marlin software and how to configure it they talked about multiple printers
being Delta the SCARA the hangar printer I'm gonna skip those because I'm not
knowledgeable in those then they also talked about the ability to add
information about your particular configuration such as you being the
author showed the boot screen they have a splash line which says what software
build it is so if you're keeping track of it an SVN where a source control
then you can add a build version right here then you can also add your own
website to the actual printer boot screen down below here we have the
ability to specify a custom boot screen right now it's commented out so you need
to remove the comments and point it to the boot screen if you don't know how to
do a boot screen you can always check out my RAMPS 1.4 tutorial on boot
screens and I guess now you can add a custom image which I haven't worked with
yet so I don't know down here you have the ability to select the serial port, I
prefer to leave this alone because default works perfectly fine
here's the baud rate you can change the baud rate if you so choose but this is
the optimized one currently so I'd leave it alone here we have a value for
Bluetooth which you can communicate with your printer board without using a
serial USB cable so that possibly is gonna be a future tutorial here's where
we actually specify our board type which is the MKS Gen L down here it looks like
we can give a custom machine name to our printer if we so choose by removing the
comments and putting in whatever we'd like between the quotes you can also do
the same thing with the serial number so if you're making multiple ones and you
want to keep track of serial numbers here's where we can add multiple
extruders it looks like we can do up to five in the Marlin firmware currently
we're gonna stick with one also we have the ability to set our own particular
size for filament I use 1.75 but I usually don't change this value because
I set it in the Pronterface software or the Slic3r software here we have the
ability to use a single nozzle now most people are not familiar with the cyclops
or a printhead called the diamond print head for a cyclops it's usually two
extruders so to steppers pushing material and it usually has one single
nozzle so if you're using that you need to remove the comments and if you're
using a diamond printhead it would be three and obviously this would be
probably be 1.75 for a diamond printhead because I think that's the only size
that you can use in it
okay some multiplexer I haven't used it so I don't really want to talk about it
but I haven't used this either but I know what it is this is a switching
extruder it uses a single stepper to push material in so what happens is
you're changing the path of what can be pushed in using a switch so it's using a
servo here to change the angle between two feet tubes
this looks very similar to this obviously I'm not super experienced in
these so I'm gonna leave them alone for now this looks like the ability to dock
your X-carriage with your extruder connected I haven't used it so I don't
want to speak too much to it here's a mixing extruder this would be something
that you would use for something like your diamond printhead where you can mix
multiple colors
this looks like when you use multiple extruders you can say what the distance
between them is so the difference is of x and y in the same plane this is a
setting to specify your particular type of power supply unit I usually just go
with the default and that's some of the setting logic that might be used for it
this is for PS_on I don't normally use it but it's used I think on the RAMPS 1.4
printer board now thermal settings this is something that we all
use normally its default negative one so I'm sorry normally it's negative not
negative one but one so if you have a particular type of thermistor to tell
temperature then you would change to the number that's specified down here below
but in our case we're gonna stick with one for our extruders so if you have one
extruder your thermistor would be one if you have multiple like a second extruder
you could say that has the same thermistor type which is one so it's a
separate set of wires running to your other extruder that has a default value
for that particular software type and the same goes for apparently a
bedchamber and also your printer bed but I personally don't use a temperature
setting for the printer bed because I no longer heat it I use PLA on it
here's the ability to set dummy values for your thermistor I currently don't
use this for anything but you have the option to do it
this is something to keep track of multiple extruders and make sure the
difference doesn't float too much this is a way to keep track between them I'm
not super sure on the actual functionality of this so I don't want to
speak to it too much and then here's the minimal temperatures that you can set
for your thermistors by default they're all five and the same thing goes for
your extruders so you can have five extras with the default Max temperature
and then your bed has a default max temperature as well then there's the
ability to actually customize or tune your temperature settings with these
values I currently don't use this but if you want more precision you can always
do that for both your bed and your extruders then here's a setting for your
default cold extrusion this prevents your stepper motor from stepping if the
temperature hasn't been reached being 170 degrees Celsius and then I guess
there's also a max length that's added down here and then thermal runaway this
is kind of important do not disable this and always keep an eye on your printer
when printing because this is what prevents the printer from either
catching on fire or breaking itself so if this fails being in the room when it
fails you'll know that something's wrong it's happened to me once so I don't
recommend having that experience this is for a core XY I personally don't use
this so I'm not gonna really talk about it here's something that we all use it's
end step settings currently there default on for use X min
all the way to the Zed min if you're using a what is it a delta then you
might have to flip the settings and enable or remove the comments for these
three but I don't use a delta so I can't
really speak to that and stop pull-ups I believe are used for additional sensors
on your hand stop I haven't used this so I'm not happy to it here's something
that we all have used and probably will use in the future
sometimes when you move to your x-axis and you type it you move your x-axis to
the end stop and you type M119 for a G code you might get false when it should
say true when it's actuated the end stop inverting it allows you to change the
logic from false to true by flipping it for you automatically down below this is
new functionality it's just been recently added to Marlin 1.1.9 this
allows you to specify multiple types of steppers they're all default A4988
but then you can add the particular situation that you have
right here for your stepper if you have multiple types and this I don't
currently use but I guess if you want to save cycles on your CPU you can always
enable it by removing the comments I the same goes for end stop first give me for
end stop noise filters you can enable it if you so choose but I don't motion
settings so distinct in factors means extruder factors so if you have unique
motor types or mixed motor types you can enable this by removing the comments but
most of time people use only one extruder so this is your X Y your Z
and your extruder these you might need to calibrate in the future I've done a
video on how to calibrate your extruder so the principle is exactly the same for
x y&z it has to do with measurement of actual divided into your what you
getting or vice-versa I can't remember the equation but it's listed above in
the calculator here we have default max feed rate I believe this has to do with
the speed at which things moves then we have default max acceleration and they
go into defaults for everything here in case you want to set them the jerk value
I believe is how fast it accelerates and then decelerates but don't quote me on
that
s-curve I'm not exactly sure but there's a link here where you can look it up and
then Z probes I've done a couple of videos on this this is enabled by
default so I'm going to move kind of quick through it you might have to
enable this in some cases for minimum for the Z-min probe and stops and then
sometimes you want to probe manually sometimes you're gonna have something
particular about it you know the distance away I'm not exactly sure these
settings but you can use your LCD panel for that that's probably why you can
enable these fixed mount probe you can use this for an inductive or capacitive
and stop for your z-axis and then this has to do with being able to stow your
probe with a servo I did a video on this a long time ago for RAMPS you can take a
look if you're interested in doing it but just remember the firmware was much
older when I did that I've also done a tutorial on the BL touch so you can
check that out on your free time and then these are a series of settings that
you can set for your probe in the beginning if you want to turn off the
power or use solenoids to extend the sled or something like that
this is used to tell positionally where the probe is in relation to your
extruder being the XYZ plane of the Cartesian plane so it
just says where they are indifference to where your extruder is located this
allows you to actually start probing inside your printer area being I use a
glass plate so I have clips so I don't want to avoid those so I probably set
this to 10 or 20 to avoid them this is the speed at which you can probe I'm not
going to talk too much about probing because it's kind of clear this talks
about another probe and what you can do with it this allows you to have multiple
probes if you so choose so I'm going to scroll through is kind of quick here we
go so sometimes when we use the stepper it goes in the wrong direction
you can change the value from 0 to 1 to flip the direction without taking the
plug out and turning it around you can also disable your motors if you so
choose they're set to false because I like to keep them holding where they are
so I recommend not changing these this is the setting basically having to do
with something with the motors I say don't change it but you are more than
welcome to experiment if you so choose
and this has to do with disabling an inactive extruder that's up to you to
play with but it's on by default here we have the ability to invert the direction
yet again so you can change the direction that your motor actually turns
so if it's going to the right by changing false to true it'll move to the
left same thing goes for your extruder and then let's see these are defaulted
off but they're experimental things that you can use for no motion before homing
unknown Z no raise so I'm guessing if you don't know where
the z-axis is then don't raise it this I believe is an offset so when it reaches
a zero position I'll go up four but it could be incorrect on this now here's an
interesting setting this is for x y and z homing sometimes your end stop is in
the wrong direction by changing the negative one to one you can actually
change the direction in which your homing rather than flipping the actual
direction that your motors turn here's the default bed size for your printer so
you have an X bed size and a Y bed size normally a heat bed default size for
most people is 220 millimeters by 220 millimeters in this case if you want to
change it to 300 by 200 you can do that here here is a way to define what your
bed looks like to the software so x-min is the zero position so these three
would be the Cartesian starting point of 0 comma 0 comma 0 this would be how
large your actual plane is in the XY so it could be 220 by 220 here or 200 as
it's specified up here and then this can also change so your height might be a
lot higher so you might be able to change this to 300 millimeters or more
depending upon how much you measure it
this I'm not familiar with so I'm not gonna stick to it as well as this
this I'm not sure of so I don't want to talk about it here's the filament run
out I've done a video on this for the RAMPS 1.4 there's actually two
different videos that have done on it there's one for a end stop sensor that I
designed that you can use to tell when you've runout of filament and there's
also a photo electric sensor to tell but it doesn't work with color or clear
filament that's why I designed the switch sensor instead bed leveling I'm
gonna try and avoid talking too much about there's about five different types
of bed leveling you can try these out on your free time I personally level with my
bed manually I'll possibly do a future video on that
but for now I'm not going to talk too much about this
okay additional features we have EEPROM settings so we can set by turning on the
EEPROM manually and then flashing our board with the firmware I don't
recommend doing this only because it makes your printer unreliable because
most of time people forget that they left on the settings and then these are
settings to make sure your computer or your printer don't go to sleep when
they're connected I personally don't really mess with them I just leave them
alone here's a debugger from watching your memory and then here's a value that
some people like to use it's inch mode support because the printer
is default in millimeters but I recommend leaving it in millimeters only
because the whole world uses millimeters except for the United States and all the
software that you use to develop your 3d models is in millimeters by default and
then thermal units I believe is the ability to change from either Celsius to
Fahrenheit but the printer is default Celsius so you might as well stick to
Celsius as well these are default sensor settings for your thermistors I
recommend leaving them alone unless you want to match them up this is a parking
feature that you can remove the comments for if you want to park your nozzle I
personally don't use it nozzle cleaning is kind of cool I haven't really used it
but if you switch colors midway through a print you can cause it to spray out
the excess so that you can get the color you want where you don't get dribble
from the previous color that was loaded and this talks about the settings for it
this is a timer used for your printer to keep track of how long it took to print
I personally just leave it alone then there's a printer counter this is number
of prints that you print on your printer it's off by default but you can turn it
on if you so wish just keep in mind when you reflash your software you might
erase your previous settings LCD and SD support as you can see the printer for
the LCD if installed is defaulted to English but there are several other
languages you can choose from if it's not there you can also invent or make
your custom language I am NOT well versed in it but you can try it out for
yourself if you so choose talking more about language then we have SD support
ST support is off by default but if you remove the Commons you can turn on your
SD Drive on your LCD this talks about the speed at which a serial peripheral
interface will work you can change speeds this is for a SPI LCD I believe
this is used for when your SD card fails it'll try a retry you just have to
remove the comments and then this is for changing around the menu structure on
your LCD this I think has to do with the movement between your menus so when
you're turning the dial or the potentiometer you can select the speed
at which it travels this is allowing you to flip the direction at which you
travel so if you're moving clockwise and it's going to counter clockwise you just
remove the comment here's the speaker most of time it's a piezo buzzer
so you can remove the comment to cause it to work or you can leave it default
off and then this talks about I believe there refresh rate for the LCD but I
could be incorrect this section here talks about additional
controllers that you can add and specify most people use the RepRap discount
smart controller just remember that you might have to load the file for U8glib
it's shown below in the firmware down here to where you can find it right
here so up here they're talking about additional types of LCDs this is an i2c
which is another way to use an LCD the ports are native on the RAMPS 1.4
next to the end stops where as I'm not exactly sure on the MKS where they
can be found at least the MKS Gen L know where they are on the MKS for Gen
1.4 I believe but they're not populated so in future tutorials I might go over
that so now that we're going through a series of LCDs I'm kind of skipping them
because it's the same information just for a particular LCD now we have other
controllers you can add support for a particular type of keypad I think this
goes for about 17 dollars but I haven't used it so I can't really talk too much
about it but all you have to do is remove the comments to actually set it
up and then extra features this talks about PWM which is pulse width
modulation it has to do with how to run a fan
looks like you've got some settings here where you can use LEDs not sure what
that setting is Barracuda is used for a paste extruder um you can invent your
own if you so choose and see if it works with it
but there might be a specific specific dot H file for this so you might have to
look it up the blink atom is an i2c LED I've done a tutorial already on this for
the RAMPS 1.4 I haven't used this so I can't really speak to it
this is settings that you can set for LEDs neopixel is like a circular LED
this is some kind of logic talking about the LEDs and what to do with them and
then finally it talks about the number of servos now there's something
incorrect I think in the firmware if you were to compile after removing the
comments for this you should get a failure because in past versions of the
Marlin firmware he had a set individual settings for each of the three so
technically it should read like this in the past I they may have changed it to
where 300 applies to all I'm not sure I haven't tested it in a while but I want
to take the a moment to thank you for watching my very long tutorial and
please remember to Like and subscribe and thank you once again for your time
