World best Cetus 3D MK2 Extended printer ! with a twist :)

IF you want silent cetus3D printer please send email for [e-mail] with request. If enough will sign, i will produce batch of pcb.
This is short video about my silent Cetus3D MK2 Extended printer with Trinamic stepper drivers. It is completely silent now, check this out !
All power electronics was designed from ground up to be as good as it can be :)

WOW I get that PCB board!!! for Cetus 3D MK3 is my Prototype Factory

[@kubectlgetpo]

Good work, maybe. Shit attitude, definitely.

[@ictrepairs6963]

Very nice piece of engeneering, congrat! Cabling as well, state of the art.

[@me438]

Wow! This is awesome! I need to try this with my printer, I'm SUPER annoyed by the noise. I would love to see the PCB design files if you ever release/sell them, that board looked nice too.

[@Kilohercas]

Hit me up on [e-mail], if i get few orders, i will make a batch of pcb for it.

[@BurakEnez]

Such annoying attitude... Do you really think that your design is a good one? Yes, the original one is horrible but yours is not very good also. Most of the hard work is still done by MCU side. You look very proud about how small your board is, it could be smaller, tough. You used a different header to make your cabling better. Now, it is achieved by MK3 version and your PCB is not compatible with new version because cabling is well managed in the new version and cable connectors are different and not compatible with your headers. I assume that your Trinamic ICs are TMC2130 and STM32 Cortex-M0 microprocessor is only used for SPI configuration of the trinamic stepper drivers. Using trinamic drivers in 3d printers are not old news. Considering standard drivers now replacing with trinamic stepper drivers such as SilentStepStick and China version Trinamic drivers which are pin to pin compatible with Ramps boards. You also talking about USB shield grounding. Yes, you are right. It is a horrible mistake. Aslos, directly connecting the shield to the ground without a proper filtering is not a perfect approach. What a giantic Capacitor in is in the middle of the board. It look very ugly and not needed. If all different axes had their own capacitors, that would be better. In your design all of them trying to leach current from only one capacitor. What about your buzzer? It is an inductive companent and when it buzzes there will occur a magnetic field. Since you forgot the ground polygon cut under the buzzer, your ground will be affected by it. Making fun of someone else is very easy. But your work is no different and there is nothing to be so much proud of. Not even all of the Trinamic company is as much proud of their extraordinary drivers as you proud of your ordinary PCB design? How much money have you earned by selling this design? How much do you think you gonna make from it? Not as much, It would be better if you would have little bit open source soul. People would be more thankful to you, if you have mentioned about how you silenced your 3d printer with details instead of how good you are. If you read my comment until the end, you dont have a life :) or you are as much angry to the dude's attitude as I am.

[@Kilohercas]

Yes, we don't have any life :) I am a bit proud, but most I am happy for what i did. It is hard to make me happy, I do BGA780 FPGAs board in my work, and this is nothing compare to it, but it makes me happy to see result, and result was better than I expected. Every one who seen my 3D printer in life was amazed, just like first time i see my axis move. Regarding complains, I have answer. Each trinamic has it's own low ESL 20uF capacitor, so that one electrolytic is just for fun lets say, and i wanted to keep it cheap if i be able to sell it. Regarding buzzer, It does not do anything to my groudnplane, and it is on the side, no currents will flow below that point. About selling, around 10 people expressed interest, at this point it is not economical for me to make complete boards for people to upgrade it, I have so many projects ahead, and no time...

[@BurakEnez]

@@Kilohercas To be able to sell a board, necessary components should be placed into the design. At least, Ramps kind of open source designes could be good example to follow the basics. These cheap 3D printers are mostly bought by hobbyists and It is hard for them to play around with the electronics. As I assumed, there is not much people who are willing to buy the board. If you share your work at least schematics would be more beneficial and people will appreciated your work more. But for anyone who does know little bit reverse engineering at least track following capability can benefit from an open source project which is "Duet 2 Wifi". Trinamic drivers are used in it, as well. You could find schematics and source files in their github.

[@Kilohercas]

@@BurakEnez You know, you have a point, that would be win-win situation in some sense, i will make separate video about it. If i try to sell it, it will be complete solution, only screw driver would be needed, all of this would be preprogrammed and tested on my own hardware ( drop in replacement)

[@cpopte]

The guy is a fucking douchebag, fuck him, his design and his fucking printer.

[@LucasGarrow]

Will you share gerber files?

Very Clean Love IT ! Hot Damn ! Sold $100.00 Need this upgrade & looking to do Good design Very Clean Love IT !

[@Martin-H]

I would consider buying this PCB as well !

[@Afro3dprinter]

Didn't know what to expect, AWESOME work, I'd buy a board where do I sign up... I've even subbed to you that was a surprise 😀😀😀

[@Kilohercas]

[@VicCatalasan]

I did similar and now its an UnCetus - Gutted the electronics replaced with a AzteegX3 controller, TMC2208 (This will quite many 3D printers) only fan noise, replaced with a lighter stepper motor on the extruder with a Bondtech BMG extruder direct feed to a E3D-V6 hotend. No mo homing to the top, which was super annoying. Hotbed with PEI sheet, temp control through a Mosfet Amp.

[@boryshacker]

Can you show some schematics?

[@davidtwine947]

Great job. I would buy this.

[@murrayedington]

Nice work! Do you plan to sell any of this eg PCB, PCBA etc?

[@Kilohercas]

Murray Edington Maybe, will see if where is a need for it :)

[@Tony-Beasley]

Linas K I would be interested in this

[@lenreeves]

I would like t purchase a board! I have two of these and it's pretty annoying when sitting next to the printers while running.

[@Kilohercas]

with my boards, you will have to check if it's printing :D But it is hard update, since you have to install limit switches, but it's like few hours of work

[@LucasGarrow]

Im interested!

[@lomborgelev39]

Do you make one for the mk3?

[@patrickrenschler]

Excellent! The noise reduction is amazing - I'd like to do a similar hack for my CR10. Can you summarize the main modifications responsible for the noise reduction? Is it primarily the trinamic stepper drivers? I may have missed it because I was watching while cooking but did you also add new steppers?

[@patrickrenschler]

I guess the fan is the big one. But I am very interested in getting rid of those high frequency CNC style noises. Those are the ones which I seem to hear in my bedroom while the printer runs in the room next door.

[@Kilohercas]

Trinamic and good oil in carages

[@dmitrysemy]

I just received my Cetus MK3. The steppers are undeniably loud, they also get hot compared to my other printers with TMC2208 drivers. I am super interested in purchasing your custom PCB. Please let me know if and when the board will be available to purchase. P.S. I believe the main board is unchanged from the MK2. The MK3 also has built in click type limit switches. I can email you some pictures of main board if you like.

[@T_TanksTinkers1066]

So let me get this straight you made a smaller motherboard that still takes the stock cpu (or tinyfab?) that uses hall effect limit switches?!

[@Kilohercas]

Jonathan Stinebaugh Yes. Since I couldn't get back EMF limit switch to work on trinamic. Goal was to make perfect printer, and I succeeded :)

[@PequignotMichel]

Waouh ! Beautiful job ! Do you think to share your schematic or to sell the PCB you designed ? Could you also share the .stl files of the plastic parts and provide the part number of your new extrusion stepper motor and fan ?

[@boryshacker]

Write him an email, find it in the description

[@davidmiedema2950]

I particulary love your custom endstops and z stabilization. Would you consider selling access to your stl files?

[@boryshacker]

Write him an email, the email is in the description

[@kpapadimakis]

Excellent work with the electronics! I just found your video because I'm about to buy one of these. Didn't realize it does not have limit switches till now. Btw, I'm also interested if you plan to sell the PCB. It would be a great addition. Thanks for sharing :)

[@lauriemcleod3082]

Where is the SD card slot? Did you eliminate that?

[@Kilohercas]

No, it is below CPU module. This is Where you download G code for offline printing. It is vital to have that :)

[@eskimodot]

Are you still selling the silent board?

[@Kilohercas]

No, but you can make it if you want

[@eskimodot]

@@Kilohercas What do you mean by that?

[@Kilohercas]

@@eskimodot you can order pcbs and assemble it yourself. I could help you with that.

[@eskimodot]

@@Kilohercas Thank you for your generous offer! I just got the MK2, will test it a bit and come back to you. Do you remember you payed for the custom pcb, stepper drivers etc.?

[@Monr3d]

@@Kilohercas It is possible to have the file to order the PCB and BOM?

[@theonlymudgel]

I’m really interested in an old project of yours. The Reflow oven video from 2014. Where can I contact you?

[@Kilohercas]

Michael Vogel megahercas6 is my Google

[@MrSp0ck]

Can you provide link for lighter/shorter stepper motor ?

[@EssGeeSee]

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

[@brantwinter]

Did you ever work this out ?

[@CarlosPuentes]

Im definitely interested in purchasing a PCB as well! I know it's been months at this point, but Id love to try my hand at assembling the PCB components myself if you dont have the time or means to produce a run of them!

Does anyone know where to buy the spring loaded belt tensioner on the cetus?

[@boryshacker]

I would buy this pcb or at least would apreciate having the gerber file

[@lauriemcleod3082]

Is your board compatible with the tinyfab.xyz CPU board? If so I would likely buy one, particularly if kitted with the hall sensor end-stops.

[@darknoktis]

Great upgrade, you are right that pcb design withing schematics is sheet, firmware is even worse. But man! You should lower your attitude, I thought you would start kissing your pcb plate. No offense, but was hard to watch, to much water and insult.

[@aaronkosminsky3793]

What is the model number of the pancake motor you showed?

[@Kilohercas]

It;s from stepper online 1.8 motor 17HS08-1004S

[@aaronkosminsky3793]

But this is a 3.5V motor, while the Cetus uses 24V motors, so how can it work?

[@clintcorbin3429]

@@aaronkosminsky3793 The short answer is the voltage rating of the motor is basically the maximum voltage you could apply to the motor CONTINUOUSLY without exceeding it's maximum current. But stepper motors are actually giant inductors, so the current does not (and cannot) instantly rise to the V/R level. The stepper controller pulses the voltage to maintain the correct current through the motor. I have some 1.8V rated steppers from a piece of semiconductor manufacturing equipment (A $2.5 million dollar tool) that used a 90V DC supply. The higher the voltage, the faster the motor would respond and the higher their top speed. But you have to have a controller that can monitor and limit the current fast enough to prevent damage.

[@addman]

Are the 3d printed supports files available?

[@Kilohercas]

Yes, I will upload it to my hackaday.io/project/162395-silent-cetus3d-printer-project-page

[@spartan3299]

You have been very quiet, busy?

[@mvadu]

Excellent.. but Trinamic drivers support better current sensing implementation, so you could have kept the switchless design?! May be you can do something like www.tinyfab.xyz folks and add full gcode support. Their software choices have bigger issues than their electronics department

[@brantwinter]

Tried emailing but no response. I would be keen to purchase a board from you.

[@Kilohercas]

Sorry, was very busy lately. Will share it with all of you soon !
