2nd Post - Understanding Supports in Cura
Posted: March 13th, 2020, 9:22 am
This one's going to be rather vague, as I don't completely understand what I am asking.
I am having a great deal of trouble understanding the relationships between the "Support Z Distance" and "Support X/Y Distance" and how the model gets supported overall. I'm not entirely sure how to describe what I don't understand. What I do know from my background and education (I'm an architectural historian) is that in order for something to support something else, it has to be physically attached and structurally sound.
I have been fiddling with the settings in 4.1.1 and am rather at odds with the "Support Z Distance" and "Support X/Y Distance" settings. Whenever I set them to a value of "0" (so that they actually touch and are valid support) the model won't slice. They have to be at some fraction of the line width in order for the program to slice the model.
What I am stuck on is this: If I have a distance between the support and the model, then what's supporting the model on that distance? The whole concept doesn't make any sense to me. I've even checked out the Settings Guide, and separate research on the 'net. And I still don't get it. For a support to actually hold something up, it has to be touching it to hold it up!
I have attached a screenshot. The red arrows indicate the space to which I referred in my original post. These occur on Layer 51 of the model.
Also, note the orange arrow, as it is indicating a little "blip" or dot of material laid down in the previous layer. (Layer 50) I don't know what to make of this either.
Before the thread goes off in unwanted directions, let me say that I know A) supports exist because of overhangs. B) What's above the layers where the supports start is irrelevant, because the issue isn't at the top of the support, its at the bottom. Duh.
Could I please get some responses to explain these phenomena?
