Internal Supports How To please?

[imk001 1]

Hello,

Using Cura 3.4.1. and trying to print a rocket nose cone to include an internal support when at 70 deg and over.

Selected Support Placement Everywhere and tried many other parameters but can't get it to generate anything that look like an internal support in Layer View.

Any ideas please how to get this to work? (Or is it just vaporware, lots of button that don't do anything) 

Far to complicated if you ask me, classic example of programmer didn't know how to make it easy so kept adding tick boxes until million monkeys scenario eventual hit the right combination.

Disappointed   in version 3 old version 15 was way way way way way way way way way way way way way way way way way better.

Though I fully agree there lot's of room for improvement on the Cura user experience....  a rant is usually not the best start to get help.....

 

Can you share some screenshots of what you tried to do or better upload the model? that will make it a lot easier to help you.

Hello and many thanks for reply

Rotate this stl 90 deg to point upwards, set infill to zero % and try to add an internal support to tip of nose eg over 70 deg.

Sorry about rant but read and read and spent hour trying to do it.

That said this 3.4.1 is way better than what 3D print ware the MS monkeys have put in win 10, boy those guy must really be high on something as doesn't seem to do anything as been analyzing  this model for 10 min and still going.

ultiarjan,

Thanks for the help, it is late now here in uk so off up the wooden hill, hence no rush finding a solution

BTW if you have contact with/or are a cura developer, well adding a scale to the print bed graphics would be nice as if you want to print in particular place on printer bed it would be nice not to have to count squares.

 

Did notice that the support it added under the recess is much better in 3.4.1 compared with v 15

 

Have a good evening. imk

Have given up... Going back to 15.4.6.

This 3.4.1 is about the most unusable software in have seen in a VERY LONG TIME and i have been writing it for 50 years!

Needs an HOW TO GUIDE

Internal supports just DOES NOT WORK!

=============== WAY WAY WAY TO COMPLICATED ==============

Life is just to short for shit like this, plus clumsy user interface compared to 15.4.6.

Bit like UK met office web site, about 7 year ago was really good, simple and quick to use.

Then the programmer wanted to keep themselves in jobs and rewrote it, now it is unreliable, clumsy and slow WOW.

That isn't going to work as you wish because the model is solid. The fact that you set infill to 0% is ignored when it comes to generating the support.

 

BTW, the tone of your posts gives the impression you're a complete dick head. Sorry to be blunt but that's how you come across. No matter, we can cope with all types here.

Dick head in your eyes maybe, but i my mind i just have a short fuse for crap.

Anyway, here's a solution. You need to use an infill mesh to alter the infill within the central region of your nose cone. The steps are:

 

1 - load the nose cone model.

 

2 - load a cylindrical model that has the right diameter for the desired infill region  and is taller than the nose cone.

 

3 - select the cylinder and use the menu on the left to change the mesh type to "modify settings for infill of other models".

 

4 - add the settings you wish to alter as shown in the picture below.

 

5 - set the global infill density to 0.

 

6 - slice, print, be happy

Hello Smartavionics

Creative solution, many thanks, going to  be couple of days before i can try it but nice one.

Many thanks imk
