Where does the wire clamp go?

Are the belt tensioner screws supposed to go in the main holes that the really long screws go through.

can you attach the file for a regular fan like you have in the pictures. Thanks!

Is the stock stepper strong enough for a Bowden extruder?

I'm using the radial fan adapter and getting a lot of stringing using a 50mm radial fan.

Bowden's typically need higher retraction settings (spring pressure in the tube), try upping your retraction distance

Comments deleted.

are you using printed ingus bearings and bearing block? how do they fit?

Comments deleted.

I say it need only one stl-file from Wanhao Mk9. Print it, and be happy)

Started the conversion on my malyan m150 today but I have one problem, how to mount the belt?

Mount the belt is not apply to this mod.

Modified belt holder for Wanhao i3 X-Axis Belt Tensioner
by JonBAL

Seems like I need to improvise a temporary solution because my extruder is broken so I can't print and have to do this mod earlier then planned.
Will post the temporary solution when I'm done.

Дорогой автор, спасибо за данный мод, но вы не учли Усадку ABS. В итоге все детали не подходят.
1)Часть, которая одевается на раму принтера под катушкой - пад в губах вал - рама не влезает,
2) сама рамка на 1мм короче чем рама - не одевается.
3) лучше убрать дыры (ромбы) Экономия пластика незначительная, а вот время печати увеличивается колосально
4) Обдув - потолок длиной трубы плоский и пластик экструдируется на весу в итоге на потолке куча соплей внтрури трубки что ухудшает прохождение потока. Стенки должны быть / -образными
5) кулер не влезает в отверстие под него опять же изза усадки ABS + дырка под нижнее ушко не там получается
6) не делайте дырки под винты 2.5мм их нереально найти! делайте под 3мм!

Ну во первых, этот сайт международный и комментарии принято писать на английском.
Во вторых, вас не смущает тот факт, что мод успешно повторён уже не одним человеком, и никаких проблем у них не возникало? С некоторыми я общался по поводу результатов и доработки мода.
1,2) Всё влезает
3) Если не хотите ромбы, то для вас есть другая версия крепления, и ещё одна версия в комментариях
4) Тут согласен, но "куча соплей" это проблема настроек
5) У всех влезает, а у вас нет
6) Дырки как раз таки под винты 3мм.

Rombic holes - my mistake they save time.. - Ok Here!
What wall thikness must be used then?
Small holes on sides for cooler mounts - 2mm bolt slide free - 3mm too big for holes - 2.5 is right
The two big holes that lock radiator - 3mm bolt slides free - need 4mm bolt
My radiator just like yours but it doesnt fit in clamps. Had to cut off radius of 0.3mm more.

I measured your model of motor mount (goes on top)and it is 50mm sharp - frame is 50mm wide. You cant print ABS 1:1 - it will shink 0.5-1.5mm guaranteed.

Does this use standard prusa i3 spacing on the X carriage? really great design, very versatile with all the mount points and such.

Wanhao i3 has 45mm betwen center of rods (on x-axis). I think it compatible. Measure your size.

What are some of the benefits of using this extruder over the stock? Besides printing at higher temps and less strain on the stepper from all the heat generated while printing ABS.

  • Different nozzles: 0.2-1.0 for simple hot-end, 0.4-1.2 for volcano hot-end (very fast)
  • Low cost nozzles
  • Less weight (moves)
    may be else anythink...

I need cheap different nozzles and make it)

This mod does not change the printing volume if we ignore the tube rubbing, right?

I mean, it is still 20cm X 20cm X 18cm, right?

Yes, if we ignore (replace stepper motor from top frame) volume doesn't change.
I added the photo. You can see gaps with Z=180mm.

Awesome, thx :)

Do i need to update the firmware?

Don't need update the FW. All work with stock firmware.

kinda a odd place for the motor/extruder. this is where i mounted mine. http://www.thingiverse.com/thing:1489794

Simple Wanhao i3 Bowden Mount

I think short PTFE tube is better (my desing need 0.5m only). Therefore more fast retractions.

I have no problems with retraction. but my tube also had much less bend/flex then yours. just a bit longer.
