*Update on CC1 Colour Changer* - https://geni.us/CC1ColourChangerUpdate
🆘 Can someone help? (*UPDATE* This is Sorted, Thanks @hurricanewin88)
As shown in the video, I’ve printed this model, but it’s *incredibly weak along the length*.
Even though it prints looking like each section is one piece, it's actually made from two separate parts that are just very closely aligned. So you end up with what looks like solid blade+body parts, but in reality you’ve got two “near-touching” halves per piece.
So, I’m hoping someone can *remix the model* so I can add plastic reinforcement rods down the length.
*What I’m hoping for:*
Is anyone able to *remix this model* to allow *internal reinforcement rods*?
My thinking is:
- *2 long plastic rods* running through the *body*
- *1 rod* running through the *blade*

Well, Eligu upset a lot of people,
0:02
didn't they? It probably wasn't a smart
0:04
idea allowing the Centuri Carbon 2 to be
0:06
revealed before making it clear that a
0:08
color-changing element was still coming
0:10
to the original CC as promised. And
0:13
based on the footage they've shared on
0:14
socials, it is at some point. But don't
0:17
worry, dear Aligu fan, because this
0:20
isn't really even a Centuri Carbon 2.
0:22
It's more of a 1.5. It's the same
0:25
machine again with a few improvements, a
0:27
few enhanced features, a few things
0:29
moved about, and it does move the
0:30
product line forward. But I think for
0:32
many a 3D printing enthusiast, the
0:35
second you see their sidemounted
0:36
implementation of color changing rather
0:39
than a separate modular and expandable
0:41
box in a world where tool changes and
0:44
multiple nozzles are 3D printing's next
0:46
top model, I'm sure many of us are
0:48
thinking, "Yeah, but that's not the
0:50
direction we hoped you'd go."
0:52
Nevertheless, this is still Eligu doing
0:55
what they've done best for years now,
0:57
stripping expensive technology back to
0:59
little more than the components
1:01
necessary and delivering a decent
1:03
workhorse at a price point that's hard
1:05
to ignore. And when it comes down to it,
1:07
whilst color changing still looks
1:09
impressive, most of us abandon it the
1:12
second we realize how much waste is
1:14
involved. Anyway, oh yeah, sorry. Before
1:16
we move on, hi, I'm Ross and this is
1:18
Fammer Videos. So, let's get through
1:21
this. And up front, I need to say what
1:23
you're all going to see throughout and
1:25
what is actually quite typical of the
1:27
brand over the last few years. These are
1:30
more budget conscious machines. And
1:32
here, I don't mean that in a bad way. It
1:35
arrives in a basic cardboard box, lift
1:37
it out by the bag, and unwrap it. There
1:40
is some building to do, a little more
1:42
than other enclosed Corxy printers
1:44
nowadays, but nothing is particularly
1:47
difficult. For the most part, this is a
1:49
simple case of remove all the foam
1:50
packaging and unbolt the bed. But you
1:53
also need to attach the screen on the
1:54
bottom. And even the waist shoot on mine
1:56
came as a separate part that needs
1:58
mounting in. Now, for a basic printer,
2:01
that would be it. And whilst I don't
2:03
have confirmation, I think it's safe for
2:05
us to assume that there will be a
2:06
version of the Centuri Carbon 2 coming
2:08
out which doesn't have this fourcolor
2:10
add-on included. It would be daff not to
2:13
when there's so many other changes here,
2:15
just something on external. So, going
2:16
back to the earlier Centuri Carbon
2:18
review, the right side of the chassis
2:20
there had a built-in recess to mount a
2:22
filament reel holder and a screw socket
2:24
for the runout sensor. So, on this new
2:26
model, I'm not sure where those elements
2:28
are going to move to, and I'm curious as
2:30
to whether Elgo expect to sell a basic
2:32
version of the Centuri Carbon 2 with the
2:35
ability to upgrade to a color changer
2:37
later. This might actually be it, color
2:39
changer or nothing. We'll see before
2:41
long, and I think it'll be fine. But
2:43
these are things I wish I knew at the
2:45
start of a new generation. And if they
2:46
do release another model, maybe that's
2:48
going to be another video for me.
2:50
Anyway, back to this one. Adding the
2:52
material change module takes a bit more
2:54
building time. You need to attach the
2:56
brackets to the side of the machine and
2:57
then slide in the filament wheels. I'll
2:59
cover these in more detail later, but
3:01
these are numbered. And whilst it
3:02
doesn't functionally matter where each
3:04
one goes, it's probably best to put
3:06
these in the places assigned with the
3:07
stickers on the chassis because they
3:10
marry up to the order of what the buffer
3:12
on top knows them to be. Anyway, you
3:14
then need to attach this buffer bracket
3:16
onto the top. Then attach the buffer
3:18
itself to that bracket, which then
3:20
connects to the machine via a four pin
3:22
cable. And you also need to manually
3:24
attach the four-way hub in the top of
3:26
the hotend before connecting the PTFE
3:29
tubes from the buffer and clipping them
3:31
together. And then finally, we put on
3:33
the big plastic lid, which is, yeah,
3:36
more of a hat. And yes, this feels a bit
3:38
cheap and flimsy, but aside from taking
3:41
up some extra vertical space, I've had
3:43
no issues with it, and it does help to
3:45
keep the noise down a bit. But that's
3:47
your fully constructed machine. Now,
3:49
externally, other than the hat, this is
3:52
near identical to the original Centuri
3:54
Carbon with only a few things moved
3:56
about, which is why I said in the intro,
3:58
this is more of a 1.5 with a few
4:00
upgrades rather than what other brands
4:03
do in terms of changes where they make
4:04
more of a whole new machine with a new
4:07
silhouette and new footprint. Almost
4:09
everything here is where it was before.
4:11
The power socket and rocker switch is on
4:13
the back, but the waist shoot is now
4:15
directly above it. This time the dual
4:17
fan outlets are a singular fan which
4:19
actually has one of the best Centuri
4:21
carbon upgrades internally, a vent flap
4:24
which opens for materials that need
4:25
cooler print environments like PLA and
4:28
closes to keep the heat in the chamber
4:29
for materials like ABS. And we'll come
4:32
back to the results of this in print
4:33
quality later. But spoiler alert, very
4:36
good. But just to point out, and this is
4:38
what led me to infer there's going to be
4:40
a simple version coming. This machine
4:42
still has an opening at the top for a
4:44
PTFE tube when not using the material
4:47
changer. Now, it would have been nice to
4:48
see Eligu plug this up. At least maybe
4:51
they have on the retail version, but
4:53
even if not, I expect someone will make
4:54
a printable plug before long. And as I
4:57
said before, the right side no longer
4:58
has the socket for the reel holder or
5:00
runout sensor in place of these four new
5:02
reel mounts. So, we'll see what they do
5:04
there if they make a basic version. Now,
5:06
on the front, this is identical to what
5:08
we had before. We've got the USB socket
5:10
right in the center and the screen
5:12
mounted to the bottom right corner. But
5:14
this is fixed, not rotatable. And we
5:17
also have a glass front door. And a lot
5:18
of people have been asking me this on
5:20
more reviews I do. So I'll answer it
5:22
here. No, it doesn't open much beyond
5:25
90°. Maybe 100, 110. It doesn't bother
5:28
me, but yes, I can see how nearer 180
5:31
all the way open would be more handy.
5:34
Now inside we've got the hotend unit.
5:36
The nozzle has been upgraded, so you can
5:38
now push it up to 350°.
5:40
But as always, I'm more interested in
5:43
the practical features of this module.
5:45
And honestly, as a user, this is and has
5:48
always been my least favorite part of
5:50
the Centuri Carbon machines. The cover
5:53
easily comes off, but the nozzle itself
5:55
is rather legacy in that replacement
5:57
still relies on unscrewing the whole
5:59
nozzle assembly, including the heat
6:01
sink, or manually heating it up and then
6:04
unscrewing and rescrewing in a new
6:06
nozzle. But the hardest part is if you
6:08
do get a clog, it's near enough of full
6:11
hotend tear down to reach the extruder
6:13
mechanics, which is proper frustrating
6:16
if it happens. Now, I'm saying that as
6:18
of yet, I haven't experienced a clog on
6:21
either of the Centuri Carbon machines,
6:23
and this one alone has done over 700
6:26
hours, but the fact is clogs can and do
6:29
happen. And when they do, it's a pain in
6:31
the ass to solve it here. Now, the Z
6:33
mechanism operates on three lead screws,
6:36
each with a guide bar. Unfortunately
6:38
though, accessing the rear lead screw
6:40
for relubrication isn't great because
6:42
it's now behind an inner plastic
6:44
enclosure, something that wasn't present
6:46
on the original carbon. So, because this
6:48
new one has an internal carbon filter in
6:50
front of the fan on the right hand side,
6:52
all of that plastic housing gets in the
6:55
way of the screw. Another extra is the
6:57
auxiliary part calling fan mounted to
6:59
the left hand side of the inner chamber.
7:01
And as for the build plate, this is a
7:03
dual-sided spring steel plate, which
7:06
actually has two sides. It has a
7:08
generally rough PEI side used for a
7:10
variety of materials with the slightly
7:12
less rough B side specifically for PLA.
7:15
But honestly, I just stuck with the PEI
7:17
side for all of my prints and it was
7:19
absolutely fine. Oh, and the build
7:21
volume is once again 256 mm cubed,
7:25
directly copying a certain other brand
7:27
on the market. Considering the amount of
7:29
designs out there nowadays on the likes
7:31
of Maker World with that build size in
7:33
mind, this means it's a solid machine
7:35
out of the box because it's directly
7:37
compatible with most of the pre-esigned
7:39
models already available. The only other
7:41
thing I want to mention in the internals
7:42
right now is a small frustration, but it
7:44
is practically annoying. And this is
7:46
because the internal base of the machine
7:48
is lower than the bottom of the door.
7:50
So, it's slightly harder to remove
7:52
debris that will inevitably get dropped
7:53
in here, which is a little bit extra
7:56
bothersome due to the large gaps around
7:57
the guide rods where things can fall
8:00
inside the machine. Again, though,
8:02
someone will probably make a printable
8:03
cover before long. But, I've got to
8:05
mention it cuz scooping crap out of the
8:07
base rather than slide it out is a valid
8:09
difference that doesn't exist now on a
8:11
few other Core XY machines. Before we
8:14
come on to color changing, I'm getting
8:15
old and I need to sit down. And that
8:18
brings me perfectly to this quick
8:19
sponsored break. This section is
8:21
sponsored by Bullies, and I want to talk
8:23
briefly about the Master Rex chair,
8:26
which you're seeing me build here.
8:28
Assembly is straightforward and
8:29
sensible. Nothing fights you. Nothing
8:31
feels flimsy while you're putting it
8:32
together, and once it's built, the whole
8:34
thing feels solid rather than creaky or
8:37
hollow. The metal base and frame give it
8:39
a reassuring bit of weight, and
8:40
everything lines up without needing to
8:43
force parts into place. Once it's set
8:45
up, what stands out is how adjustable it
8:47
is in ways you'll actually notice. The
8:50
lumbar support moves up and down so you
8:52
can actually line it up with your back
8:53
properly. The seat is wide with rounded
8:56
edges so you're not perched on the edge
8:57
of it. And the armrests adjust in ways
9:00
that will actually get your arms sitting
9:02
naturally instead of shrugged up or
9:04
stretched forward. It recines smoothly.
9:06
And yes, it has a built-in leg rest.
9:08
That's not something I use often when
9:10
working, but when you lean back between
9:12
jobs or you're just watching something,
9:15
it's genuinely comfortable and easy to
9:17
use. Material-wise, you can choose
9:19
between their Ultraflex PU or water
9:22
repellent fabric in a variety of colors.
9:24
I went with fabric because it's more
9:26
breathable for long desk sessions, and
9:28
it feels durable without being stiff or
9:30
plasticky. Overall, this feels like a
9:33
chair designed to be used everyday
9:35
rather than just photographed for a
9:36
product page. It's comfortable,
9:38
adjustable, and well put together cuz I
9:41
did it myself. No, I'm kidding. If you
9:43
want to check it out, there's an
9:44
affiliate link in the description, and
9:45
any current offers or coupon codes will
9:47
be listed there as well. And yes, I
9:50
mostly like it because bullies rhymes
9:52
with ghoulies, and apparently I'm still
9:54
12 years old. Now, this color changer,
9:57
or canvas, as they call it, I'm not
9:59
going to call it that. As far as
10:01
material changes go, I just don't think
10:04
this is the direction people want to
10:06
see. It feels legacy budget. External
10:09
enclosed boxes that help keep filament
10:11
dry or sometimes even actively dry it
10:14
are much more versatile and expandable
10:16
tools which are far easier to add to a
10:18
device later down the line. And again,
10:21
you can normally daisy chain them and
10:22
multiply them. Just sticking four reels
10:25
on the side in the open air when
10:27
filament is very susceptible to ambient
10:29
humidity isn't the way to go. But then
10:33
at the same time, I've got to remember,
10:34
I've also said for a long while now that
10:36
even though color changes exist, just
10:39
how much material a multiolor print
10:41
wastes and how messy that waste can be,
10:43
the feature you've paid for here often
10:45
gets relegated to no more than, "Ooh,
10:48
that was cool the first time you use it,
10:50
but never again." So honestly, as I've
10:52
said before, the bigger value in these
10:54
or any of them is the small convenience
10:57
of not having to manually heat the
10:58
nozzle and then hand push filament to
11:01
and through it. And then the reverse
11:03
every time you want to change it. So the
11:05
value here longterm, I think, is more
11:08
that. And I actually reviewed another
11:10
brand recently who have an external dual
11:13
reel autoloader, which I actually think
11:15
serves more value to people than this.
11:18
But on the flip side, if you do want it,
11:20
this works. Just be aware you can only
11:22
use filaments where the reels have an
11:24
inner diameter of about 52 to 58 mm.
11:28
Otherwise, they either won't mount on
11:29
the pegs or they'll fall off. And Eligu
11:32
now has filament with RFID tags. And
11:34
they're apparently making their own open
11:37
RFID format so that other brands can get
11:39
on board with this as I found out at
11:41
Form Next last year. Check out that
11:43
video for more. Okay, not more. Well,
11:45
actually, it's the same info, but please
11:47
watch more of my videos. Now, this isn't
11:50
quite as automated as other machines
11:51
where you just put the reel on and it
11:53
automatically detects it. What you
11:55
actually do is scan the RFID against the
11:58
reader on the side of the buffer and
11:59
then you get a pop-up on the UI which
12:01
asks you which slot you're mounting it
12:03
to. So, it is straightforward. Now, just
12:06
before we go on to print quality, a
12:07
couple of quick notes about software.
12:09
The UI of the machine is pretty much
12:11
what we've had before and is now rather
12:13
standard across most printers. They
12:15
have, of course, added the menu for
12:17
filament loading, which is handy because
12:18
setting your filament type and color
12:20
here then syncs back to the slicer. But
12:23
speaking of, this is Eligu's version of
12:25
Orca. It's basic, but it also doesn't
12:28
try and reinvent the wheel. And there
12:30
are some elements that have now become
12:32
common of printers using this same
12:34
firmware and slicer combo, such as the
12:37
simple ability to cancel part of a print
12:39
mid-print. I actually had one of several
12:42
parts fail and come away from the bed
12:44
during one of my earlier prints. And
12:46
rather than just cancel that item,
12:47
allowing the rest to continue, I only
12:50
had the option to either cancel the
12:51
entire print or just allow the printer
12:54
to extrude a spaghetti-ike mess in the
12:56
area of that part until that small piece
12:59
was complete. So, I chose that one. And
13:01
there was no sign of the printer
13:03
detecting the spaghetti and pausing.
13:05
Another thing I noticed with this
13:07
machine is that print time estimates
13:09
were wildly off. I printed a lot of
13:11
multiolor parts on this machine and jobs
13:13
with an estimate of say just over a day
13:16
ended up taking more than two. So this
13:19
is something they really need to get a
13:20
hold of and dial in. Now the machine has
13:23
a camera which generates time-lapses.
13:25
But getting these off the device is a
13:27
more arduous process of exporting them
13:29
to a USB drive rather than doing it
13:31
remotely in the slicer. And it's also
13:33
quite a low resolution camera. So, your
13:36
resulting time-lapses are at a pretty
13:37
poor quality of 640 by 360. But this
13:41
brings me on to the biggest thing Eligu
13:43
lacks, a phone app for basic remote
13:45
monitoring. Now, Eligu now have the
13:47
Matrix app, but so far this is only for
13:50
their resin printers. And you can access
13:52
the printers UI via a web browser by
13:55
just typing in the IP address. But to
13:56
monitor this outside of your own home,
13:58
yeah, you need to do some local network
14:00
fiddling on your router. But when it
14:02
comes to overall print quality, this has
14:05
been solid. In fact, it's been one of
14:07
the best printing experiences out of the
14:09
box that I've ever had. My first Beny
14:12
print was absolutely fine. First layer
14:14
test was near perfect with only a small
14:16
sign of underextrusion in the front
14:18
right corner. Now, yes, this isn't
14:20
perfect. I said near perfect, but this
14:22
is certainly above par for most FDM
14:25
printers that I've tested. And when it
14:27
comes to ABS, I ran off a full 3D print
14:30
test that showed decent surface quality.
14:32
All parts printed first time, bridging
14:34
was clean, and even the overhang test
14:37
outperformed my Prusser Core 1L, which
14:39
is a review I'll have out shortly after
14:41
this one. Subscribe so you don't miss
14:42
that. Now, this machine has no internal
14:45
heater. The chamber heats passively
14:47
using heat from the build plate. And I
14:49
must admit, the one thing I wish it did
14:51
was at least wait and let the chamber
14:53
warm to temp before starting a print.
14:56
But for the most part, this works and it
14:58
works well. Now, I had to wait a few
15:00
days for Eligu to send me some filament
15:02
as they asked me to do a large project
15:04
on this and supplied the materials for
15:06
it. So, I used up the ends of several
15:08
rolls I had printing a Final Fantasy 7
15:11
Buster Sword. And I told the printer
15:13
that all the rolls I loaded were the
15:14
same color when printing this. So, when
15:16
one ran out, it would just move on to
15:18
the next. and it had absolutely no issue
15:20
moving from one to the next every single
15:23
time I had a run out on all four reels.
15:26
To be honest, I wasn't even going to
15:27
show this model. It was just something I
15:28
was doing for myself. But I wanted to
15:30
bring it up because if there's anybody
15:32
watching who could please take this
15:33
model and remix it with two ball holes
15:35
through the full length of the blade so
15:37
I can add some long plastic rods for
15:39
stability, I'd be eternally grateful and
15:41
thank you in a future video when I
15:43
reprint it. A link to this model will be
15:45
in the comments if anyone can help me
15:46
with that. Also, while I'm asking for
15:48
favors, what do people in the UK use for
15:51
plastic welding PLA? Because I can't get
15:54
my hands on that gloop stuff anywhere at
15:56
a reasonable price. Anyway, yeah. So,
15:59
Eligu asked me to print a large
16:01
multiolor print for this video and said
16:03
they'd provide me with the filament to
16:05
deliver it. I got the printer for free.
16:06
They haven't paid me to make the video.
16:08
Printer filament for free. That's how I
16:10
do all my reviews. All the words I'm
16:12
saying are my own. They've had no
16:14
oversight over this video, but they
16:16
wanted me to show off color printing
16:17
because this is their first multiolor
16:19
printer. So, I printed two of these
16:21
frost axes from the Eternal Forges last
16:24
campaign. This took over a week, nearly
16:27
2 weeks, with thousands of color
16:29
changes. And one part of it even has
16:32
five colors. Now, in order to do this, I
16:35
added a pause in the job to do a swap
16:37
out. But unfortunately, and I tested
16:39
this a few times, the printer seems to
16:41
completely ignore that instruction in
16:43
the G-code. But because the gap between
16:45
these different colors, I had more than
16:47
enough time to do a manual swap between
16:49
the blue finishing for the rune block
16:51
and the start of the red gem. Now, on
16:53
these prints, the dimensions were a
16:54
little expanded. I actually struggled to
16:56
screw these parts without lubrication.
16:59
Yeah, giggity giggity. But anyway, once
17:01
I added some grease, they did connect
17:03
up. But the main point is during
17:06
printing, I had no issues. This machine,
17:10
like the Centuri carbon before it,
17:12
performed like an absolute workhorse for
17:14
hundreds of hours. But I do think this
17:17
waste also shows off the earlier point I
17:19
made about color changing because I had
17:21
to move this around my room during use
17:23
as I had other projects on the go. And
17:26
yeah, I think I'm going to be picking
17:27
out bits of filament from under my
17:29
cupboard for months to come. I did try
17:31
printing a small waste model, but after
17:33
my first print, I realized this was way
17:35
too small for the task I was
17:37
undertaking. So, I just took it off. But
17:39
again, someone will probably have a
17:41
larger solution available before long,
17:44
if not already, and I just missed it.
17:46
But let's conclude on the printer. So,
17:48
as always in my reviews, I like to just
17:50
break it down straight for you and get
17:52
to the point. This is a budget printer.
17:54
when you look at the price versus the
17:56
competition for the features you get.
17:58
And you've seen me sour on cheap copy
18:01
brands before, but I think this one is
18:04
an example of how to do it right. Even
18:07
in the resin space, Eligu have a track
18:09
record of understanding the key elements
18:11
we want as customers and delivering them
18:13
at the most affordable and competitive
18:16
price points possible. And they do that
18:18
by stripping things back. No glass lid,
18:21
money saved. The screen doesn't rotate,
18:22
money saved. lower resolution camera,
18:25
money saved. No app, no STL storefront
18:27
when better ones already exist. Money
18:30
saved. And that saving is passed on to
18:32
you. But yeah, there is a cost there
18:35
because there are still some software
18:36
elements that exist on other machines
18:38
like the ability to cancel parts or add
18:41
pauses and hardware elements that are a
18:43
bit outdated like long nozzle swaps and
18:46
bad extruder gear access. But this then
18:49
just comes down to your choice. And at
18:51
least this time it's a clear choice. You
18:54
know you're saving money when you buy
18:55
this machine. You get issues with all
18:58
printers, not just mid-tier brands. But
19:00
here, Eligu, instead of pretending to be
19:03
just like the best printers on the
19:05
market, but actually offering a poorer
19:07
quality experience with only a small
19:10
relative saving like some brands,
19:12
savings which will probably cost you
19:14
more in the long run. And you know the
19:16
brands, the ones I mean the ones that
19:18
embody that meme of your mom telling you
19:20
you don't need a bamboo A1 because
19:21
you've got an A1 at home. Yeah, those
19:23
guys. Here, Elu have found a better
19:26
market gap. In fact, they've actually
19:29
found a market gap without all the
19:31
pretense, misdirection, and marketing
19:34
by actually leaning into and I
19:37
suppose even being proud of their budget
19:39
conscious position. what they've
19:41
delivered here stripped this back
19:42
sensibly whilst passing a bigger saving
19:45
on to you. Yeah, they've got some
19:47
software work to do and we should
19:49
absolutely but kindly add pressure on
19:52
them to resolve these things and update
19:54
these features. And when they do, I'll
19:56
update the description of this video.
19:58
But the point is, if you're looking to
20:00
buy the most powerful 3D printer you can
20:03
on a budget, this is definitely one I'd
20:06
recommend over many of the others. just
20:09
decide if you want color changing or
20:11
not. But even if you don't, the
20:13
automatic loading is still handy. So, at
20:15
the end of the day, you know what this
20:17
is? Sensible savings without the
20:19
I want to say thanks for
20:21
watching with a huge thanks going to our
20:23
members who are on screen now. They help
20:25
keep the lights on and generally just
20:27
encourage me to keep doing what I'm
20:29
doing, as do you for watching my videos
20:31
and dropping comments. So, please do
20:33
that if you've had a good time. As
20:35
always, there are affiliate links in the
20:37
description if you do decide to pick up
20:38
this or any printer I review or even any
20:41
product. Clicking those links before
20:43
making a purchase really helps me
20:45
because I make a commission at no cost
20:47
to you. Above all, I appreciate you
20:49
being here. So, I'm just going to leave
20:51
it with until next time. This guy are
20:55
sick. Fammer out.
