Manually add/remove support structures

[deonholt 0]

Hi and thanks for the help.

Can someone please point me to some tutorials about this. I have read some blogs and watched videos and a "block" was mentioned in mostly all instances. How do I remove unwanted support. I cannot seem to find this block or how to draw it.

I will really appreciate your help & advice.

Thanks.

On the left of the Cura workspace screen is a toolbar.  The bottom tool is "Support Blocker".  Select your model and then select Support Blocker.  Click somewhere on the model to create a block.

On the lower left there will be a list of the objects on the build plate (oddly enough called the "Object List").  Your new support blocker will be Eraser and additional blocks will be added to the list.  You can make them active by selecting them on the list.

When you select the Eraser block you can drag it around or type numbers into the Move tool dialog.  You can also scale it separately in all three axis.  When it covers the proper section of your model you can also elect to have different settings for the intersection volume between your model and the blocker (it's under "Per Model" settings just above the blocker tool).  I found that if I wanted to block support AND infill from an area that I needed two blocks covering the same area with one set to infill and the other set to support.  I haven't played with that aspect of Cura a lot though.

Thank you very much for a very thorough explanation. Really appreciate your help & time. I got it to work.
