On today's episode I'm going to update a ender 3 pro
with a 32-bit board from big tree tech. I'll show you how to do it
and how to update the firmware on today's Filament Friday.
Filament Friday is brought to you every week by these patreon supporters.
Here's the board I'm going to use it's the big tree tech skr mini e3 version
1.2. There's also a version 2.0 but we're
going to work with the version 1.2 today. It's about 36 dollars,
version 2.0 which is a little bit later is about 10 dollars more.
So let's get this installed let me show you how to do it.
To get access to the board there's one screw on top and then these three on the
bottom that you need to remove so we can take the cover off. I also
suggest you take a picture of the wiring so you know where everything is at and
then here's the replacement board and it matches up exactly to the old one.
So we need to take the old one out and there's four screws. I just use a
screwdriver and pliers so I don't lose those little
screws and then you can take the board out.
And then we'll swap the wires so one by one I disconnect
and then try to connect on a new board. But a lot of these are labeled
so it's not a big deal to pull them off and then install them later.
And then these other wires need to be unscrewed with a little screwdriver. I
try to do these one at a time that way I get it in the
right slot and everything lines up. And once you get
everything installed now we can put the board back in place
and it lines up those same screws. Put those four screws back in place make
sure the sd card is in its slot in the front and
then route all the power wires so they don't get pinched.
I did notice that the fan cooling the electronics does not run when the power
is on. You can actually swap the two connectors.
The cooling fan for the filament should be on the lower connector and
then this fan on the upper connector and then when power is on this fan runs
all the time the same as the fan on the hot end. And then the filament
cooling fan is controlled by the pwm. I powered it up and everything looked
good. The menu is a little bit different, I went into printer info and you can see
this is running bug fix 2.0 so this is old firmware. Updated
firmware is already available here's the site to go to. This is all the
information on the bigtreetech boards. You go here download the zip file it'll
download everything. Unzip it and here's the firmware. There's
a version 1.0 version 1.2 and 2.0. I have a 1.2.
Now there is a bltouch with z homing and a bltouch but I just want the
standard firmware. So this is the one I'm going to download
and put it on a blank sd card to install the firmware. We shut power
off, insert that sd card with the new firmware
turn it back on. It'll take a few minutes and then the screen will come up
and you briefly saw that it's updated. But let's go to "About Printer" >
"Printer Info" you can see now we're running 2.0.5.3 the latest version.
And I'm happy to report that my bed leveling g-code
works perfectly on this. Click the button, it moves to the next spot so I can level
there and then when i'm done I was able to
print my squares. It came out great. I used some fiberology fiber silk gold
and this vase came out beautiful. And this has been around. There's a lot of
people that already have this on their machines,
so it's proven to work really well. There's also now
a version 2.0 and I got this one. I'm going to install this on a different
machine. I wanted to try the 1.2 and see how it
does. Another thing you can do is put on a glass bed. I've shown this in a
previous video, that you can just pop a glass bed on there you get a nice
even level and really at that point you've got the core of the
Ender 3 v2. Because Ender 3 v2 is a 32-bit board and
a glass bed. Now you don't have the adjusters, you can
easily add those. I do have the knob, I have an EZR
on this which is my favorite extruder for these. But
overall you can build your own v2 essentially by doing this.
Now there's one caveat. Some of the new Ender 3 pros
are coming with a 32-bit board. The same board that's on the Ender 3 v2.
Why creality is doing this, I don't know. If they ran out of boards or what? It's
not every one but it's popping up in different places.
I'm trying to find out if this is going to be something they're doing in the
future or if this is a temporary thing but several people have commented that
they can't run my bed level on their brand new Ender 3 v2. Well that's
why. It's running the creality firmware which doesn't recognize the m0 command.
So my code doesn't work. But this does. The big tree tech does. So
if you want 32 bit on your old existing Ender 3 or Ender 3
pro? This is an easy way to do it. I'll put
links to all this in the description below. If you like
what i'm doing here maybe check out some of the videos that are popping up
and maybe click on that CHEP logo and subscribe, that way you don't miss an
episode. I'll see you next time right here at
Filament Friday.
