Today we're going to talk about how to install the CB1 a Raspberry Pi alternative
on the BigTreeTech Manta M8P so I need to tell you a couple of things real quick here
there are several different boards that you can use obviously there are Raspberry Pi boards that
you can use either with eMMC or without and then we have uh two iterations of the board I'm going
to use the most current which I believe is v2.2 but I'll double check in just a second
and we're going to install it here and there's little connectors on the bottom right here
that'll connect to but I need to show you on the underside of the board what's going on here
so on the underside of the board they have two different slots they have the MCU which loads
the actual firmware and then they have the OS that you can load over here on the other card
so let me flip this back for a second and let me grab one of these boards hopefully
I'm grabbing the most current and this is v2.2 for the version
so to place this on top you have to align these I use the holes as a way to tell and also the
actual uh antenna is facing towards the edge of the board for all of the boards
so I'm gonna align it over the holes and then I'm going to press down and you'll hear a click
and that should put it in place next I'm going to attach the antenna and this has a little
cup on the bottom that will click over the actual connection over here so you just align it like so
find the actual cup and then push down and that's all you have to do to set up the antenna
next we need to image this now I already have firmware loaded on this and I've placed a jumper
over here for five volts of power through the USB so we can connect to the board so what I'm going
to do is I'm going to place this in the drive and then into the computer so you may hear a beep
and then I'm going to go over to the desktop and show you a couple things real quick here
is the Marlin (BTT) website page for GitHub and this will actually show you what you need to know so
if you click on repositories and then type Manta you'll see the Manta 8. now you can download this
folder by clicking the code button and then saying download zip you can check issues over here with
the board and then of course you can also check on the CB1 by doing the same thing so this will bring
you to the CB1 and inside of here you'll have the latest system images so if you click here
there's version 2.2.0 unfortunately I'm not going to use this one tonight I may update the video in
the future but there seems to be an issue that I'm having with a particular pin in the actual
printer config file so I'm going to skip that for tonight and we'll do image version 2.1.2 this one
will have a slightly different issue you have to use two different passwords whereas this one
for the c or excuse me for the M4P version of the Manta you can use one password so let's click on
this to get the image file and I already actually have the image file so it's downloaded already I
click this right here for Klipper and downloaded this so let's go over and set up the actual image
okay inside Raspberry Pi imager version 1.7.3 you're going to click on choose image
use custom you're going to select the actual image that we downloaded click open then we're going
to choose the actual media which is the storage then we'll click right and yes now this may take
a few moments to actually image so I'm going to pause the video and resume after it's completed
okay now that it's almost done verifying and just finished we're going to click continue
then we're going to go over to the desk for a second I'm going to pop out the drive
then I'm going to place it back in the computer then on the computer what I'm
gonna need to do is I'm gonna need to go to the boot then I'm going to right click on the
system configuration here and edit with Notepad++ now you're going to need to put in your Router
name right here and then you're going to need to put in your Router
Password now you're also going to have to do this down here for Router name
and then Router Password
and the reason that I'm telling you this is because this particular build you need to do
it for both otherwise you won't connect so I'm gonna do this off screen and save it and then
we'll continue from there okay so I've saved this so we're gonna go back over to the desk
and pop out the drive then I'm gonna place this drive inside of here but I'm gonna use
tweezers because I don't want to pick up the board so essentially it goes right in here
if I can get this in here correctly let's see if I can do it this way
there we go so we're going to power this board and we're actually going to use a display as well so
I'm going to show you the display inside of the recording so you can see it and then we'll sort
out later on in a future video how to use it so this is currently powered down but it does have
five volts for a jumper so we can power it over here so I'm going to Power It Up in the computer
and then I'm going to change the display so that we can check so if we're if we've done
this correct we'll see a little display of it loading which apparently it's doing
so this may take a few moments so what I'm going to do is pause it until it
comes up and then we'll check on the computer what the address is
okay so it's now finally came up so we know that it's actually working for the
display so now let's go over to the desktop of the computer and check the router now I
have blurred out this section up here because this is private to my network
but down here we're going to click refresh and we're going to see if it shows up as an
IP address it should be like CM or CB1 which it is it's the BigTreeTech CB1 so we're going to copy
the IP address which is 192.168.1.3 so I'm going to open a new browser and paste it in here
and this will bring it up now there will be issues so we're going to actually have to look up
first of all our configuration so we're going to go to machine you can see that there's currently
a little setting here for pointing to a configuration so we're going to have to place
our configuration in here as well and then point it to it so I already have it open in a folder so
I'm going to use this one right here which is the generic Manta I'm just going to drag and drop then
I'm going to right click rename I'm going to copy this then I'm going to cancel click on printer
config and then I'm going to highlight the name that's currently there and then paste it in then
I'll click save and restart now we actually have to fix the MCU issue that's inside this file so
if we clearly scroll down here you can see that this is the default so we're going to click on
our Terror term session I'm going to open a new session and I have to double check the address
so I'm going to blur it out again well actually I can see it over here it's three so we'll change
this to a three it's going to be TCP Port 22 and it's going to be SSH which is Secure Shell
so I'm going to click ok now the password is going to be b i q u for both the username
and password so I'll click ok and if you don't know how to change the password it's uh 'sudo passwd
I think but uh currently I'm not going to change it because we want to
find the information that is in regards to our installation so I already have a Klipper
for the actual installation and what we're going to do is we're going to use the ls and
it's going to go to the dev serial and buy ID uh folder right here and then anything in there
it's going to display so I'll right click copy that go back over to the terror term right click
hit enter and this is our machine for our address so I'm going to right click on it to copy it then
I'm going to minimize this go back over here and I'll show you what's going on so if I type serial
colon space and then hit Control V you can see the addresses are different so that's why
we had to do that so I'm gonna hit enter at the end of this line
to space it out and then I'm going to save and close now there is one other issue that
we have to deal with on the board we don't currently have our thermistor is attached so
I'm going to attach those so that we don't get a second warning but I'll show you what it looks
like real quick if we try and do a restart here there's going to be like an ADC message
hopefully yep so ADC out of range that means there's no thermistor so let's go back over
to the desk for a moment I'm going to grab two thermistors I'm actually going to plug these in
while it's powered with 5 volts because it's not going to do much damage but usually you should
power off the board so that is for the actual heat bed and that one up there is for the first
extruder so you can see the thermistor down here so let's go back and see if that fixes the problem
so let's do a restart again otherwise we're going to have to do a restart of the machine
being a firmware restart so let's see it's having an issue so let's do firmware restart
and see if this fixes the problem so if it does fix the problem we'll be able to see
the dashboard which we can see now so to test this I'm going to go back over to the desk for a moment
I'm going to pick up one of the thermistors for the hot end and I'm going to place my finger and
thumb around it then go back over to the desk and we can watch the temperature rise over here
so that's the basic setup obviously you're going to have to make changes to this and
possibly updates but at this time I want to thank BigTreeTech for providing me with the Manta
M8P and also the CB1 Raspberry Pi alternative I also want to
thank my patrons for their support without you I wouldn't be able to
make these tutorials as well as the people that donate on PayPal
I'll place a thank you note at the end of the tutorial so thank you and I'll talk to you later
