Dude lol, I find it hilarious how much you love the cetus. I find it pretty under engineered. It is basically ignoring many 3d printer advancements over the years. No self adhering heated bed. Non geared, unconstrained direct drive extruder that makes flexible almost impossible. No type of pressure advance. At least it has a rock solid motion platform with the rails and belt driven Z. It seems like a printer stuck in 2014. Still, I bet an enclosed coreXY printer using a e3d Hemera extruder, running a duet with Reprap firmware and pressure advance with a heated removable flexible pei sheet bed and hiwin rails would blow your mind. You could run prints at like 250mm/s with acceleration values of like 3000 with damned near perfect quality. You can literally lift the printer by the extruder with a geared dual drive system. If the filament could hold the weight that is. You should build one up to the standards of your sick CNC mill. Go crazy with it. Ball screws, Hiwin rails, heated enclosure with water cooling. I wanna see you print some engineering grade plastics like PEEK and PEI.

I was about to comment about how great the timelapse at the beginning looked, never saw any 3d printer timelapse that smooth! Great you explained it, awsome what you came up with

It's a joy to find a place like here, with such a good and informative technical content. Thanks.

Top quality videos, interesting topics, good humour and regular uploads. I feel bad that you don't have more subscribers and views. Keep up the good work!

Your videos are AMAZING, and they always make me think of "look around you" for some reason...

awesome work. the time lapse stuff is impressive - as is the heated platform...thank you!

Love your videos. I was waiting for another about 3d printing, finally!!

Very cool video. Pls don’t stop them coming

You pack a lot into a short time always fun and interesting to watch. 👍

Awesome timelapse concept! Thanks for sharing.

Qualitiy video as usual! Informative, funny, well edited. Keep up the good work!

Great video. Pre ordered my Cetus MKII few weeks ago so whenever it arrives maybe I will get one of those cameras and set it up like you.

Dude.... You seriously have an awesome brain. 🤔 your attention to detail and ability to explain things are enviable. Awesome work.

How do you not have millions of subscribers?? Best channel on KZfaq.

Really alot of good work in this one video... impressive and entertaining

That's actually really nice!

Oh, Marco. In addition to providing some very informative videos, you're the only person who manages to make me bark with laughter at least twice in every one of them. And I won't even mention the sexy "Terminator" voice... Oh, wait...

i love your dry sense of humour Marco ! BTW pass on my best regards to surveillance snake, if he's watching.......

Nice! I like the OpenCV work, I have just started looking at that library.

Your humor is fantastic!

Great enclosure build with aluminum frame and acrylic window panes.

I noticed! It was absolutely butter!!!

I'm liking your videos more and more

OctoPrint has a nice Timelapse feature, that only takes a snapshot when it detects a z change in the gcode. Does exactly what you want, makes beautifully smooth time lapses. Especially if you attach the camera to the heated bed.

With Marco Reps, I can learn something and watch comedy at the same time. Multitasking education.

I built a wooden box around the cetus, but had to add also a 12V fan. The stored heat was messing up the z-axis and the belt started to slip above 50°C. I also printed the fan extension from thingiverse for 60mm fans, since the factory 40mm fan is with 38db a bit to noisy and you can buy 60mm fans for less than 5euros double your cfm and reduce the noise to 21db.

Man, you're crazy! Had to subscribe!!

surveillance snake is watching

Just love your channel! Fkn great!!!!

I love this channel

Great video !

I think PETG pretty much made ABS obsolete for most - but not all - use cases. It's sooo much easier to print than ABS (no enclosure needed, but you need a heated bed) and is super strong. Plus it can make a really detailed print when you have those settings tuned in so no vapor smoothing needed.

Marco Reps You need to make a shop tour video. I and I'm sure a lot of people would like to see all your equipment and the space is occupies.

I love the foreshadowing XD

very useful information

love your video

Reflector button/switch on plate. Take photo when aligned. You can also make a manual version with a button magnet and paperclip

Nice timelapse! I actually did something similar recently... by injecting gcode to take a snapshot every time the Z axis changes and move the hotend away to a fixed location before taking a snapshot.

If your getting good results with that build platform then more power to you! Expect curling edges on larger parts as you get close to the edge of the build platform and other problems due to how uneven it is, but if you don't print things that have those issues, then it's a solution that works well for you! I haven't seen a resistor based heated bed for years. Nowadays, even most of the the traditional PCB based bed heaters are considered uneven. :)

Octoprint does the timelapse on z change with a plugin. Also lets you load/monitor prints wirelessly on your home wifi connection.

I like when you were drilling your finger. Very nice.

I noticed the time-lapse clip at the beginning ;)

I use an electric wok to vapour polish my parts. It works very well and has no open flames.

Neat! I've been using OpenCV on a Pi Zero with a camera to catch my cat stealing food from my dog's bowl. Just gotta figure out what to have it do to get her to stop, maybe spray some water using an actuator or something.

Smoooth. That's "smoooth". With three o.

Coole Videos, hast ein Abo

I like elp cams. Ordered a 1080p h.264 to connect to the trinocular port on my microscope. c to m12 adapter for like 6 bucks, 15 buck trinoc tube to c adapter and 45 buck camera beats the hell out of the $200+ most places want for an entry level scope cam. i have 2 of their 720p hardware h.264 units and have always been pleased with the price to quality ratio

I used your power resistor idea and it works great. Using a cheap RAMPS 1.4 board to control the power. Went cheap on the box though of 5mm thick wood planks:P You REALLY need the box if you want ABS, the warping is bad.

I have a small question. When you print with PETG material, are you using 24VDC or the original 19VDC? Because the printing temperature required by PETG is too high, I am not sure if my V2 extrusion head can reach this temperature, using 19VDC. Thank you

"Surveilance snake likes its freedom, as much as it likes taking it away" lol!

Thanks for sharing :-)

Nice video! put the part in the fridge or freezer before acetone smoothing

I just took apart my cetus hotend and the heater cartrige is labled 24V 80W, so no problem there with the new power supply.

Marco Reps, great video, but with a heated build chamber, how does the electronics and motors deal with 60C/140F ambient temp? Control electronics can overheat at those temps.

:D your videos are so awesome. Ah, and thank you for the tip with skimage, wasn't arware of it at all.

I like Ron's glare.

The cetus 3D printer is a great printer I've actually wanted one but near the end when you showed that camera setup it looked really awesome would you possibly make a video on setting that camera up and 3D printed parts.

Nice - I've also always wanted to build a temperature controlled enclosure, just with a simple temperature sensor and a fan to get the warm air out, if it gets too hot (the cold-end would not get sufficient cooling any more and the filament would start to flex). Though I've always told myself that I'd build a better 3D printer one day with linear rails instead of rods and all and then also build a nice enclosure. Now been doing that for half a year and still haven't built any of those things :P

That's a beautiful view through the window and on the roof of another of your Cetus vids. Southern Germany perhaps?

My guess is that your room temperature was too low, so the acetone would evaporate very slowly. Try the same process, but put the (very) closed jar on top of the heated bed, while it's heated at 50ºC. A few minutes should do the trick :)

I've never gotten vapor smoothing to work without some heating. The boiling point of acetone is ~50C so it doesn't take much. It only takes 30-60 minutes at most. Once you're happy with the result, let the part dry out for a while, it will have soaked in the acetone (which acts as a plasticizer so it might be temporarily flexible).

Looking at getting a cetus3d largely based on your reviews, but the software is holding me back. I want a slicer I can tinker with. Ive seen they added support for importing gcode from other slicers; but on their own forums all I see is misery in trying to get that to work. Is that sampling bias? Do you have any experience, say, importing gcode from cura?

would you ever implement the trinamic tmc2130 stepper driver inside cetus printer?

Can't you use a limit switch or proximity sensor to automatically take photos in the same positions?

You are a very odd individual. That's probably why I enjoy your videos so much. I about spit my coffee out with the finger circle....

ELP camera from China. I use those in my DIY pick and place machine vision system

6:12 I have the same OCD problem with my Cetus3D 😎

Very nice time lapse solution! Did you manage to get a true continuous single outline corkscrew (aka "vase mode") print out of your Cetus? Unfortunately their proprietary firmware seems to have problems with very small Z-Axis steps.

love your videos man but I have watched them many times already. can you do like a pod cast about anything. Ill be your first subscruber.

Looks very comfy. Do they sell the controller board separately?

Most Caps run on 16V so if your running anything above that ie:24v they will blow up, thus causing the magic smoke you had!

oh hey you have an s7 too have you noticed occasional pops and ticks in the audio?

Ich Feier so sehr dein Kanal 😃 Kannst du bitte n Video über Präzision von led sla ducket machen wie zb Turbo Fan impeller und Festigkeit von uv resin machen? Ich bin so unglaublich neidisch über dein Wissen und Fähigkeiten! Und die geilen Sachen die du machst! 😃😂 OMG! Mach weiter!

Could the timelapse thing be done with any USB camera or even with Raspberrys own camera module?

try PETG... excellent fillament material

Good morning Marco. Great video as usual. Quick question: have you looked at potential bed warpage issues with that aluminum plate now that its heated? Reason I ask is that when you demonstrated the overheating of the PLA, you could really see the aluminum distort.

Great review!!! Please review a large format delta printer capable of poly carbonate.

do you have a spec sheet for the power resistors used?

Nice! Can I ask what polycarbonate are you using? And did you need to change anything with the heater? I thought that PC needs a nozzle temperature of ~300C, and the Cetus can only get to ~260. Thanks :)

🤔 Would you be able to extemd the X axis if you have the equipment?

Do know how to 'clean' the Cetus platform? Do you use Blue Tape? Questions like that...

You could have used something like a usb heating pad or a 12V 10-50W heating pad instead to make sure it's even spread. Or even a thermoelectric cooler as they would reach their own temp limit of 70.

Thoughts on printing with PETG? I’ve read a lot recently saying how it’s easier to print than ABS, and stronger.

Hi Marco, do you any chance have dimensions for the enclosure? I want to try building an enclosure for my cetus and can use some help.

Try heated vapoursmoothing and you'll get a much better result :) Otherwise, great video!

@Marco Reps, are you still as happy with the Cetus printer? If it is accurate enough for a guy building 1 ppm voltmeters at home, it is good enough for me.

Hi Marco, I always enjoy your humor in your videos. Which of the many available ELP cameras did you get? For instance the lense size? I see a 4mm lense available, but is that the best? There are fisheye and 180° view lenses available as well. Would you reveal the model number please? (drumroll)

Blew that old carbon comp resistor right in half, impressive

Do you think you could break this printer down and pack into a pelican 1430 case?

Hi Marco what nozzle are you using, and best settings for good prints on the cetus, i just got the cetus ext. thanks for your videos

Why does the acetone vapor polish look so bad though? Isn't it possible to get it to be even glossy when you erode so much detail with acetone vapor?

wich temp you use for PC filament?

Nice Timelapse, you could try to use a photo diode and a laser at the end of the printer to signal the snapshot Zevs Richy

can you amazon link to your clear sheets?

What I want to see is glass reinforced nylon printing. Probably nozzles would die after some time, but that structural strength! I also heard about ferrous filament. Printed brushless inrunner motor project for example??? Maybe printed stepper motors? 3D printer printed on a 3D printer???!!! ;-)

Mit dem Vaporbath geht deutlich mehr, schau dir mal n paar Videos dazu an, man bekommt abs quasi Spiegelglatt wie Spritzguss. Wie immer ein cooles Video Daumen hoch :)

Thank you, very nice video, as always! Keep up the good work! - could the cetus be modified to be used with a laser to make clean laser cuts thrue paper?

You have a Kaypro? Cool!

My brand new extended cetus mk3 caught fire and they said i was the first. My question is why did they have thermal runaway off?

you should defenitely try the vapor smoothing again, that didnt look like it worked at all, some people warm the aceton a bit up, to get more vapor...
