[Filament strands on the edge of vertical holes above bed height]

I am looking for a way to prevent strands of filament being formed by the initial pass on a vertical hole that has a support structure under it.  I use the default roof support interface and invariably get strands of filament on the edge of holes as shown in the attached image. 

 

I would also appreciate any suggestions to get a cleaner "roof" in parts like this.  The spacing of the filament on that first supported layer is so bad that it looks like some of the support is still attached to the part even though it seemed to separate easily.

Shell\Initial Layer Horizontal Expansion = 0.0 fixed the issue.  Thanks.

 

I have found this technique to work fairly well when you want to create a small housing with labeled controls.

[Strange First Layer sliced in Cura 4.8]

I use Cura to slice dual extrusion parts with text on the first layer that can take the place of a label. In older versions of Cura this worked fairly well.  But 4.8 has a strange first layer that causes very tiny spots of filament in place of my text.  The second layer is OK but the small bits of filament laid down on the first pass don't adhere well to the build plate and the part is ruined.    I have attached images of the first layer from Cura 4.2 and 4.8 to show the differences.  Any suggestions on what settings might be causing this?

[A nice storage container for filament]

I found this storage container at MTM Case-Guard.  It is a perfect fit for 8" reels of material once you pull out the foam insert.  It has an o-ring seal to keep moisture out.  They also make one without the insert but it is army green colored and I'm not a fan.

I am using EXMAX® Reusable silica Gel Desiccant to keep the reels dry.  

The little balls of silica gel turn from blue to red when they absorb moisture and they are re-usable if you throw them in the microwave to drive the absorbed moisture out.  The only down-side is the crummy plastic case they use.  I will print something up that is more durable and can take the microwave heat.
