Cheap 3D printer with 3 linear rails - How the Cetus changed my mind 

The combination of your accent and no-nonsense tone of voice makes your silly humour work so well.

I always enjoy your videos. Perfect balance of serious review with that dry German sense of humor that gets me every time.

Dude... my car has been running on rotten fruits for years. I have no complaints

This is the first time I've seen one of your videos, and you've totally won a new subscriber. You give us a solid, useful review of a technical product - which alone would make it extraordinary. Add your deadpan delivery - as dry and understated as any I've ever seen. Remarkable work, and fun to watch. Bravo!

yay watched the whole thing with a smile on my face

Putting the printer “out of the way” was hilarious on so many levels.

I was one of the original Kickstarter backers, I got the first gen Cetus for $240 including shipping

Pipe organ builder? Now that IS cool. 18 years ago, I was doing pro audio and found myself in the lowest bowels of Uptown Chicago, beneath the moorish-styled Aragon Ballroom. My assistant and I thought it appropriate to explore the tunnels, reportedly a refuge of one of their more infamous denizens, Al Capone. Two levels beneath some gigantic leaf springs which suspended the dance floor, we stumbled upon several very large relatively thinwall pipes. From a dark passage a man emerged, startling us. He almost seemed like he was waiting for us. Very friendly, the man explained he was the resident electrician and He invited us into his warren. Quite homey, if you like museum-quality electrical equipment and pipe organ parts... I do. This man maintained Aragon's three manual, ten rank WurliTzer Opus 1897, from the factory rebuild of the two-manual, ten rank instrument from the Pelican Theatre, Klamath Falls, Oregon. For the life of me, I can't remember his name. He is likely sleeping with the angels, given his advanced years. He told us that his primary gig was rebuilding pipe organs, and the Aragon was a side job. Lovely, lovely man. He gave us the $.29 tour, then we bid him auf wiedersehen. I walked away feeling as though I'd completed a heretofore undiscovered bucket list, and I could now die. Lavay Smith and Her Red Hot Skillet Lickers never sounded so good as that night... partly because I strongarmed the bonehead mixing-board dude into not showing off our 150,000 watt sound system we configured and turning it down and let the most excellent acoustics of the Aragon do the heavy sonic lifting. Phase cancellation is a b**tch! Speaking of death, Aragon's mighty Wurlitzer exacted a fatal toll upon one Kyle Kirchoff (RIP) in 2015. Seems our tragic and probably un-sober subject found his way up to the catwalk around the domed plaster ceiling above the main floor. He crashed through the plaster, fell, and was impaled on the organ's pipes. Ouch. A lesson that one should consider: a bosun's chair is one's friend whilst engaging in such activity. Curiously, Chevelle, the Chicago band playing at the time didn't notice and continued playing, stopping only at the behest of Chicago's Finest. "Chevelle": a sometimes muscly, but mostly crappy contraption out of Detroit's glory years. Aptly named. Have seen Iggy Pop, Nirvana, Hüsker Dü, many others at the Aragon. Stopped going there because I'm old, tired, and found that urinals are not the walls. Did I digress? God forfend. Cheap linear rails, oh yeah! Stick-slip, plentiful, cetus3d, et robotdigg, all making our motion-control more controlled. Good times! Herr Marco Reps, there is a certain youngster in Chicago - J., who won't stop talking about his semi-famous RU-vidr friend. Seems your rep is circulating around the NYLF/Envision STEM camp at Loyola University lately. These rugrats are adopting little, quiet, dry ways, and thinking this is funny. Hahaha. It is insidious and must be stopped. Someone will report you to the authorities and you will pay! However, we will visit you in your new "home" and bring you a nice raisin cake and maybe some tea. No beer allowed. At your release tribunal, your appreciation for Aminita designs will count to your favor. BTW, Kooky (film) may soon be featured at a regular film night we have at CTS Orthodox ch. in Chicago. Real love makes things real.

I love your sense of humor great machine by the way ...

I love the monotone delivery of your one liners 😂😂😂 This looks like a fantastic machine. I was looking at building my own corexy style printer with linear slides, until I saw this... Now I may have to pick one of these up. Thanks!

Wow ! I was just thinking about cartesian printers with real linear rails yesterday, awesome video!

Your sense of humor is amazing! Loved the video, and got a good laugh ever so often from your presentation. Einen schönen Sonntag wünsche ich noch allen.

Please cut more rubber prints in the future

Great video ! Well explained and documentated. With a nice sense of humor. I love your workshop.

Loooved that ending.

Unlike cnc machines the print bearings don't come into great sideways force on a 3d printer so linear bearings are far less of a problem.

Wow, astonishing quality for the amounts of views and subs, you got me, suscribed

Great review! I’ve been on the fence about the Cetus, primarily due to the small build volume, though without a standard heated bed it’s hard to justify getting one for your primary printer. If there’s a fairly straightforward way to add a heated bed I would leap at the chance to get one since it’s just so darn sexy compared to the plastic construction of most other entry-level printers. I did end up backing the maker’s Kickstarter for the newest design they’ve created since it’s a lot cleaner (And includes automatic bed leveling!), and looks far more professional than the cheap, no-name printer I started out with, which is always such a huge pain to use. The new design is your standard printer (i.e. no linear slides), but it integrates a lot of know-how and design experience to really optimize for a reliable, easy to use printer for a wide range of materials. Sorry, can’t remember the name of the new design!

great video and great sense of humor

Chimney Rooftop CNC... I LOVE THIS MAN

This looks worth investing in. Made me laugh when suddenly it appeared on that chimney stack :) You have a great sense of humour....love your videos.

I just ordered my second one of these. They're great!

I don't always like RU-vid videos, but when I do I like yours...

Funniest video on 3D printers and printing I've ever seen. I really like your sense of humour ;-)

Great video You had me laughing with the PCB agitator. And for that my friend, I subscribed.

I love your channel!!! I work vit Chermans effree day (Henkel) and your accent and humor is perfect!

Bei so einem Winzling sind die Linearlager auch echt nötig. In dieser Qualität können die konkurrenten ohne jene Lager auch drucken. Dennoch Daumen hoch, dass er von Anfang an so gut eingestellt ist.

Did you ever find the FT-5? It only has linear rails on x-y, though...

First vid I saw from you, I like your sense of humour, I'm subbing.

Nice finale. Thanks for a review. I was looking for info about using linear slides for all axis on my new large machine build.

I like your style my man, keep it up! Subscribed!

As I looked at your 3D printer setup and the hot glue gun, I laughed out so hard, because this was exactly the feeling I had with my first 3D printer years ago :) Thanks for sharing such great videos!

Really love your Videos:D please continue your work!

We produce high temperature resistant all-metal linear guide blocks

You offer me engineering knowledge and a smile

"I don't care, just give me the parts" Exactly my feelings about slicers, and one reason I like Tiertime products.

Very interesting and funny video! A Cetus 3D is now on my shopping list. Thanks for the info!

As usual, another great video. I just love the scripted humor being delivered through an awesome Germanglish. Thumbs up and subed. Going to the channel to find ( hopefully ) the video on adding " a " bed heater to Cetus

I'm going to save this video just in case the internet breaks, this deserves to be seen by future generations.

Showing the build volume with the cardboard mock-up is VERY effective. Excellent review: I have found the 3-D printer I will purchase! I would like to hear more about the heated build platform control since it appears to be a fixed temp per the mfr website. It is amazing so good for only $450!

The linear rails combined with ball screws would be the ultimate for long term accuracy.

Wow, Cetus looks pretty good, pricing is very palatable. That said, I was considering backing the Kappa 3D printer on Kickstarter (not for meme reasons Krappa). Do you have thoughts on their design?

I can watch your videos , even if i don't care about the items you describe!!!! Your presentations are among the best I have seen!!!!

A thing I saw on the Marble Machine X channel was creating a stable chamber for it to work in. I suspect changes in temperature is the enemy of accuracy once you've got those fancy linear things.

God start and ending(with humor), and fine video in between.

as a cetus owner, I can only agree. great vid

Where is the screen? I have a Prusa I3 MK2 with proper roller bearings and spring belt tensioner

Neat trick for leveling flex prints!!!!!!!! What material did you use? TPU?? I'll try it

Truly an inspirational man!

Thank you, an excellent video both in content and presentation.

super geil, mit der Klebepistole :D ....you made my day!

Nice solid construction. Makes me look askance at my prusa mk2's less-than-shiny-and-gradually-breaking 3d printed components and "I found these at the bottom of my parts bin" y-axis screws.

WONDERFUL JOB, LOVE THE CHANNEL!

I love dry German humor. Had a friend once with the exact sense of humor. Priceless, especially for Anglo's like myself.

I know I'm a few years late, if you still have this printer, I'd love to see how the stepper motor actually drives the rails, ie closeups of how the belt is run and connected to the moving bed. A follow up video would be great :-)

The hot glue fun taped to the machine...A+

wait, you actually get the LEFTOVERS!? SWEET :D

I like how they don't put too many plastic crappy parts on the machine.

Oh gawd I love your style! Keep it real

Excellent video. The highlight for me was learning about using back-emf as a virtual limit switch. Gonna see if I can get that working on my cheapo Banggood laser etcher.

There is an argument to say linear bearing are a worse choice than the cheaper simple lightweight bearings here. I built a laser cutter from scratch once and used linear bearings like this. The added friction from the grease and ball bearings induced quick a lot of backlash from the added friction. If I had to do it again I would go for something cheaper and lighter.

Damn, I wanted to build my own! These prices make it a tough choice. Really nice construction and size. Wouldn't the electronics heat up from being below a heated bed though? If you were to include one. PS love your vids.

2:54 I love the barely audible “Jeeze…”

Don't let RU-vid get in the way of your, uh, important work.

Have you tested the alignment of the axes to eachother? How is the alignment for X and Y established, since the user has to mount the turret theirself?

Nice printer, waiting was a wise choice. If you're adding a heated bed an AC powered silicone mat with an SSR works wonders, specially in a small form factor. ABS makes for pretty prints but that is about it, I've found CPE's to be a good compromise between usefulness and print quality.

I took your vid to heart love my 3dprinter now any one out their that can do this go for it its worth it

what's the stability of the bed like with just a single actuator in the middle?

I'm thinking of getting one of the larger ones as my first printer. There are so many choices of printers. More important to me than options is the thing works consistently and reliably. Is it easy to find parts and add-ons for it later to print with different materials? Is there a Plexi case available for it? How is the warranty and tech support? Has anyone had to go through RMA or support? I'm saving for an X-Carve and wondering if I should get this printer first. I already have the router and rest of the tools for the X-Carve. I have actual products I want to produce with these tools.

Great video and you got a sub the cetus is a very nice machine ive been wanting one for a wile

Who says Germans doesn't have any humor!? You sir, proved them wrong! Thnx for the great vid

Great topic, thanks 👍

They put IKO LWL12 B linear rails on this low cost printer. These rails are super expenisive. I wonder how they make any money on this printer.

I love your humor.

how compared to the monoprice mini? they are almost same price

Have you made process on the heated bed? I'm wondering if nicrome wire mod of the standard bed could work

1:52 had my heart stop and look at my printer

I subscribed the moment I saw the 3D printer on that roof.

Dein Video ist ja zum schießen. Voller nützliche Informationen, und auch witzig. Ich habe vor drei Tagen eins von diesem bestellt, und freue mich schon sehr über die Möglichkeiten. Ich finde auch das simple Design faszinierend. Mal sehen wie schnell das Ding von China nach Sydney, Australien ankommt.

I work, assembled machines with the same structure, only they have, a tank between the rails. My problem has been aligning the rails on each side, to ensure parallelism and squareness. The rails are located at a distance of 3 meters from each other. Do you know any technical and effective alignment system. Well, I do it empirically with a tensioned steel wire.

I done some work with linear synchronous motors. They are in a way stepper motors, but not that exact. Make me wounder, is it possible to make a linear stepper motor? Maybe using something like 9/10 gearing.

I'd love for you to throw your humor into quantum anything, I'm laughing already!

This printer is pretty good, the only downsides are the .2mm nozzle clogging a lot and the need for rafts/a rough bottom of print. For 300$ though, it competes well with the wanhao duplicator

What flexible filament is that? First time seeing hot air smoothing, kinda curious to try it out now..

Did you get those machine for free by Cetus? Because according to Maker's Muse, people reported lesser quality rails on the retail version after he poster his review.

As a fellow fussy engineer, I commend your drive for precision.

Every time you said 'biggy' with a German accent it cracked me up, thanks for that! :D

RIP 3D printer 0:35. It did disassemble itself before it had change finish building itself.

No heated bed and small build volume for 300$. Nah.

Do you know what the highest temperature is that the nozzle can reach?

Informative and entertaining as well

I have already invested heavily in a DIY printer, but it struggles because i lack access to another printer, the parts are just crappy. Gonna buy the Cetus and re-purpose my existing printer. Great video man!

i subscribed after watching and hearing the sense of humor.

You really should try the Original Prusa i3 for 3D printing. It is the best consumer printer atm

Could you replace the fan for a aftermarket (noctua) fan?

Not enough for milling, but what an awesome and simple construction for printing

Nice power screwdriver, where did you get it from ? or what is the brand ?

Great review

You won't have great luck with ABS without the "fancy design" of an enclosure.

great sense of humor :D
