[Changes made to material unavailable until cura restart]

Hello

to calibrate what is known as extrusion multiplier in S3D I change the filament diameter in material settings, making it bigger when over extruding and smaller if my prints are under extruded.

w

When I change filament diameter the modification is not available instantaneously and if I jump to another material and come back it's the same, no changes to material are available.

I must shut down cura and restart it to see modifications. Is this normal?

 

thanks 

[Setting parameters for new material]

I think you must go in manage materials and then create a new one or copy an existing one and then modify settings at your needs..

[Material disappear from list changing diameter]

Found the problem. My Machine must have 1,75mm compatible nozzle otherwise the material disappear because not compatible..

[Material disappear from list changing diameter]

Hello

I'm learning to use cura (3.2.1 - MacOS El Capitan).

I'm Trying to create my own materials.

I click on create then change Brand to group with other material of the same brand and then I set a different diameter, from 2,85 to 1,75mm

As soon as I change this parameter my new material disappear from list...

 

Am I doing something wrong?

Thanks   

[Feature request - Extrusion multiplier - where is it?]

Hello,

coming back to this post to clear some doubt.

 

In Simplify3d there is the "flow" parameter that for a 1,75 filament should be lowered if in over-extrusion and risen if in under-extrusion condition.

If I correctly understand  this can be achieved, in cura 3.2.1, changing filament diameter, with lower diameter for under extrusion condition and higher diameter for over extrusion.

Am I right?

 

Then

there is some problem in filament selection in cura

If I create a new filament and I set all parameters (temperature, retraction speed, filament diameter..) and I select a filament from the drop down list in printing profile, then the diameter of the filament under material section is not updated.

I must close and restart Cura (version 3.2.1 on MacOSx HSierra).

Anyone could confirm this?

 

Thanks

Pietro

Flow in cura 3.2 isn't set in material profile, it is relative to print profile, so it changes with let's say layer thickness and other print specific settings.

If you select different material in the uppermost section of  sidebar flow don't change in a given print profile..

Just an idea:

Perhaps it is possible to change the according setting for material diameter instead.

This has the same effect (change of the extruded volume) and should be stored together with the material.

Nice idea, I'll try some hollow cubes to see if this work as should be.

Thanks!

If you are making a new one, just duplicate an existing profile and then edit to rename and put in your values.

Ok now I see, I must duplicate a material and then rename it and it's brand and a new section appears under brands..

Not much intuitive.

 

By the way, extrusion multiplier could be a nice addendum

 

Thanks again

Pietro

Thank you kmanstudios

so I must enter flow % for each material manually without saving a new profile each time?

Is it possible to ask for adding this feature to the software - if feasable?

[Feature request - Extrusion multiplier - where is it?]

Thanks I see...

But this is something that is not linked to a particular material.

I mean, different material could behave differently (by over extrusion/under extrusion point of view) to the same extruder settings (fine tuned steps/mm).

On my machine I fine tune the actual filament length extruded with caliper and set fine tuned steps/mm this is a value saved to my firmware (eeprom) settings.

Then Each time I change a filament spool I make a new calibration process, with thin wall - single shell hollow cube to measure if the wanted shell thickness is what is actually printed.

The ratio between what is "wanted" and what is "achieved" is my extrusion multiplier for a given material on a given spool.

So for example I print PLA Tech with 0.96  extrusion multiplier, Pla wood with 0,92, PETG with 1.03 and so on.

 

So I would expect to find extrusion multiplier in "materials" tab under preferences, because each "material" has its own fine tuned extrusion multiplier on a given machine..

Flow percentage in Cura’s settings panel is fixed for a given profile and doesn't change when I change printed material..

 

In S3D I can save extrusion multiplier with material settings, together with hot end/bed temperature and fan speed for first layer and consecutive ones.

 

Is it possible to do the same with Cura?

 

Thanks

Hello

I'm new to cura 3.x, I am trying to use it instead of some other slicers (S3D)

 

In Simplify 3d and many other slicers there is an option to fine tune and correct the extrusion, i.e. extrusion multiplier.

 

Where is this value located?

I thought it was in material management but it's not there and I can't see it elsewere

 

Thanks

Pietro
