[Rotary Dual Print- Head]

I made the experience as an designing engineer that you get better results (keep it simple) by talking to a team which gives you total new ideas! Perhaps you´re kinda get blind for it more and more when you get closer to your own approach

Mhm, lets call them "nozzle masks".

Yes, but i prefer a softer material like high temperature silicon toned in a mold, to prevent the nozzles for weareout. Trying to do only the standart retraction for the filament (except for the material which dont like to stay a bit longer in the nozzle).

All red parts are neodym magnets (inside the transperent green parts the red ones are more orange), the orange parts are dumpers mounted with the magnets on a adjustible base to calibrate the nozlle hights.

atached some photos of current print status

Maybe i can finish the mechincal work on next sunday, but i could need help with the software / firmware part. I want to use the sripts which can put into the toolchange scripts in simplify3d, but i don t do something like this before.

Nice, I have been trying to make something like this as well, but didn't get very far.

 

Hi Deto,

you want to turn the head by servo?, do you know how to trigger a servo in marlin?

On the first try i want to do the switching with the x-axis, arms and ramps, but maybe after this we could do a servo mod if you want.

Nice design!

Reg. questions - never ask for it :-)

How are the dimensions compared with the UMO head (e.g. nozzle position), what about the additional weight and how do you secure the position in the print state?

Thx drayson,

the dimensions are quit well i only loose in X-direction about 7mm (compare to single nozzle) because of the rotation. The rotation is from side to side 24° (12° left / 12° right). In Y-direction i loose about 20mm (maybe i can optomize this down to about 10mm). The position of the print state / the rotation of the half print head is secured by magnets which can be adjusted- sliding around the X-axes centre (ill upload more screen shots soon). I don t compare the weight of the original printhead to the new design right now, but based on the dimension and the fact that the most parts are printed in PLA (axial bearing too - (only balls are steel) ) i think it isn`t much additional weight.

Hi there,

i am upgrading my ultimaker orginal from standart dual extrusion to a rotary printhead. I got inspired of the rotary printhead long time ago but i did never started to design my own one for the ultimaker till now.

here are some videos which inspired me:

My goals are:

-having fun

-no oozing

-fast switching between heads

-very light printhead to keep the accelaration high

-printing without prime tower, ooze shield... to save print time

-using magnets for rotary fixing

-using the x-axis to switch between the heads

-get a easy to print design in the end so anybody who want it can print it

-integrate e3d v6 hotends

-upgrade to e3d titan extruder (not on the printhead)

-customise original firmware

-generate printing profiles

I already redisigned my first dual head (never printed only disigned) to version 2

Old design:

New design:

-new bearing rotary axes

-more magnets (clamping of the hotends fan duct)

This only the beta type to try out the mechnical characteristics of the rotary axis.

I already printed 75% of it, pictures coming soon

Feel free to ask questions, and of course if you have further ideas tell me.

Greetings Zeno
