[Change Print Speed]

Wow, an encyclopedia of information in one post. Amazing! Thank You

The speed is off because you are Ironing at 50mm/sec and everything else is at 75mm/sec.

I didn't have the Ironing Speed visible and when I enabled it it was set at 25mm?

This is with the Infill Density at 20% and all of the Lightning angles at 50° and I've changed the Top/Bottom Line Directions to [0,90] so the first skin doesn't fall into the gaps as much.  This allows for better support for ALL the skins.  The heat problem is still there but probably not as troublesome.

I inserted all these settings and try them out today.

This is good ole' Grid infill at 15% density.  You can see that the first layer of skin is well supported.  If you set the Infill Layer Thickness to 2X Layer Height then the infill only goes down every other layer.  That decreases the time penalty (vs Lightning) to about 7 minutes. 

 

I'll try this one next

It also results in a much more robust part.

 

True.

In the past I would make these as hollow tubes and they worked well, I decided to try to use end caps to see if it would be better. I even tried to print the end caps separately and glue them in place

The part is only 2" diameter and bridging should work but it might be necessary to add another top layer.

 

Some of these models I make are up to 4" in diameter and your robust settings may be just what is needed

 

Winter trees is hollow and works well. The fern has a top and bottom layer and is 4" in diameter (yet to be printed

@RonS the 3mf file opened as a model file.  Use the "File | Save Project" command to create a 3mf project file that will contain your settings and printer as well as the model.  (When you "Export" from Cura an option is for a 3mf model only file ... no printer or settings.)

 

With just the model to work with and using my settings I get this.

 

Everything is at 75mm/sec except for the outer-wall because I have it set to 50 and that's what all the speeds in the gcode show.

 

Hi Greg, thanks for replying.

 

Here is the 3mf file saved as you requested

TopLayerTest.3mf

FWIW, I have the same problem and I was hoping someone has an answer.

 

I'm trying to get a better top layer that doesn't sag

Cura behaves different with placing a model  as a .STL or .3mf file.

 

Ok, I think I understand what you are saying.

 

My model was centered in Fusion 360, but when placing a 3mf file it will land on the front left edge because that is the nature of the beast?

 

Thank you for taking the time for such an in-depth explanation 

[.3mf File drops in on left front edge]

Hi Dustin

 

I've turned that on and off to see if it helps, it didn't make a difference either way. I guess I took a snapshot of the screen while it was still on.

 

Is there something else I might turn on or off?

 

Thanks

[.3mf File drops in on left front edge]

When I load a 3mf into Cura 5.2.2 the model drops on the left front edge. I know I can move it to wherever I want using the cursor but I was wondering if there is a setting to have it drop in the center.
