Kossel Air autolevel and print

[@nekomuraねこ丸]

Hello Mr Johann Rocholl You are the developer of Kossel and Rostock 3D printers. I am blessed with that benefit. Thank you

[@jtaylor330]

No fan or heatbed and still a quality print? Impressive. Im designing my own kossel mini reprap and I always enjoy the Tri-frame models like this one.

[@carlosgomesribeiro9569]

Olá Johann, tenho uma kossel mini e não consigo fazer funcionar o bed leveling , pode me ajudar? obrigado

[@mechanisma22]

Do you have any tips for carrying on the printer on the plane? I plan on taking my small delta 3D printer like this and want to make sure TSA won't give me problems.

[@fragapple]

Hi, where did you get the belttensioners/clamps from?

[@JohannRocholl]

Kossel Air (formerly known as IATA Kossel) is the little brother of Mini Kossel. It is designed to fit in overhead hand luggage bins for air travel, and has successfully traveled between Seattle and New York. In this video it's printing a Nexus 4 Wireless Charging Orb Cradle by pixil3d: www.thingiverse.com/thing:89762

How do you solved the oozing-Problem with this printhead? shorter filament tube? higher/lower temperature? more filament retraction than 5 mm? a tip would be nice... ;-)

[@JohannRocholl]

10 mm retract with NEMA17 direct drive, 100 mm/s retract speed.

[@bytebrand-org]

Oh thx, i will try that!

[@JohannRocholl]

***** Marlin's Configuration.h says #define DEFAULT_RETRACT_ACCELERATION 3000 mm/s^2 which means we spend 0.0333s accelerating to 100 mm/s. Probably we should double or triple the acceleration setting.

hi am from Ecuador I would like to buy a 3d printer which recomiendad me and where I buy thanks

[@ConnorWidtfeldt]

When will you release this? I'm really hoping to build one.

[@widgity]

did the probe imprpve quality much? I have pretty much the same setup, but don't use the probe. never had an issue with first layer, but I'm eondering of it's worth investing the time into getting the probe going?

[@Nomoreidsleft]

Do I the rods have to be so long? Can I use shorter rods printed on my TOM?

[@HReality]

Yes, its an open source design in yes they are indirectly for sale. The BOM is available online as are the printed parts and other parts trick is there is no one stop 'kit' available.

[@bdh4]

Looks great, Johann. Are you going to release or give pointers to the new parts that aren't on the github repo, including the gt2 belt clips and glass clips? Also, is this 210/550? I found mine, at 210/500, would almost fit into carryon luggage, but the cutout for the handle would get in the way. A slightly larger carryon would probably be large enough. The power supply fits, but is super tight. Thanks!

[@bradreed1395]

what filament is this on the green frame parts? it's beautiful!

[@nrdesign1991]

IDK if this is out of place, but my x-axis seems reversed. The motor setting is correct, but when I command the printer to move 30mm to the right, it goes to the left. I had to reprogram the deploy/retract coordinates to make it work at all.

[@RichardTheValiantFoolFox]

next time instead of firmware changes simply flip the connection between the motor and the board.

[@Unmannedair]

Richard Fox This is probably exactly what is wrong.

[@nrdesign1991]

Richard Fox Unmannedair Thanks for the replies; I had since forgotten about this comment. I ended up flashing the original firmware, swapping the motor connections until everyhing ran as it should. Since then I made some changes on the firmware, such as a longer watchdog timeout (the printer froze and turned off its fan when a stroke took more than four seconds), and also removed the jumpback to the main screen in the menu (the printer freezes for a fraction of a second when the GLCD display is updated, which leaves marks on the printed object).

[@vborgnet]

Files STL to print pieces of structure ?

[@JosenivaldoBenitoJunior]

Johann, do you have a detail picture of the auto bed leveling mechanism?

[@JosenivaldoBenitoJunior]

Never mind, I found the thread with details.

[@kalabrichizante]

Josenivaldo Benito Junior please, can you share this link.?

[@JosenivaldoBenitoJunior]

[@oleglyan]

The question is left, which is more energy efficient? This Delta printer or Makerbot?

[@blakebrown8314]

Probably delta because you could run off of 12 volts

[@idkzero]

would this printer be more accurate and faster than a prusa type 3d printer?

[@mtys11]

Yes, it takes more time to calibrate it, but once its printing, this type of geometry is an absolute beast (I got 3 of this printers)

[@melissaoliva6206]

Could you tell me what type of material did you use for the arms? Or what type of arms did you use to move the nozzle? Thank you

[@happyvalley808]

Melissa Oliva They are carbon fiber. goodwindsdotcom

[@broerbreaker9240Z]

Nice job ^^ Realy loving the auto level, wich was a pain to do manual i believe.

[@cleberalves3952]

Hello, Your auto leveling doesnot use a servo motor?

[@sanjeevgangaraju5967]

How much did this printer cost?

[@hholover1]

is it just PLA it can do?

[@Deathbynature89]

I've forgotten, is this an open source printer design and are these for sale?

[@francoisrougier4342]

is anybody knows how to implement auto level ?

[@matthewlaberge]

Looks great!

[@jamescullins2709]

Where is the Z probe used for bed leveling?

[@Traqr]

+James Cullins You can see the Z-probe at the back of the head at 0:30 when it gets pushed up into "print" position by plunging onto the extended bolt.

[@jamescullins2709]

Mine uses an inductive prox sensor, can't tell if that one is inductive or plunger type Thanks for you response

[@cloroxbleach7837]

It look nice!!

[@les_ruk_]

Share G-Code?

[@brunonovais8801]

wtf.. that video is in fast forward ?

[@ThomasCharron]

The video has the speed in the upper left hand corner..

[@heyarn]

sweet!

[@yurrry]

3D принтеров уже дофига, а стоящих или функциональных моделей почти нет совсем. Одну ерунду печатают

[@dimadiman3093]

А какие по вашему стоящие модели? Интересно узнать!

[@yurrry]

dima diman Вот это стоящая модель =) vk.com/hi_3d?w=wall-30905681_59324

[@dimadiman3093]

Я не пойму, Вы мне дали ссылку на фото что кто то, где то, когда то напечатал? Или я пропустил сам 3D принтер? Меня интересует и сам принтер, а фото как то мало, ибо с фото можно "поработать". Дайте ссылки на сами 3D принтера, именно тех моделей, которые так печатают и желательно видел глянуть.

[@yurrry]

dima diman я говорил о 3D моделях, созданных в софте. 3D принтеров и так до фига, ссылки найдешь по всему интернету. Там и печать резиной, и пластик+резина, и разрешение от 0.02мм. Но все они печатают одно и то -же - сову на ветке, бошку мастера йоды, болтик с гайкой, механизм из шестерней, кубики, вазы и прочую херь. А 3D принтер может печатать удивительные вещи, но их никто пока что не печатает толком. Потому что нужны крутые 3D-моделлеры, которые и создадут эти вещи.
