Too many supports

diamonddog · May 31, 2022

Every time I go to print my one item it adds soooo many supports that it adds days to the print and when it is done printing there are so many supports

it is impossible to remove it from the supports without destroying it. Is there any way I can get someone to help me with this. My Cura has only a 3 selections under supports

one being Generate support and support placement and support overhang angle. that's it. No way to choose what type of supports you want or anything else.

I have been trying to print this for DAYS and not sure what to do to fix this. If you can help me with getting a STL ready to print with a minimal amount of supports

that would be great. Also my cura does not show where the supports are going before i print sadly or allow me to delete supports etc.

Any help is great. Thanks again

There are about 73 support settings. You must be in one of the basic views.

To the right of the Search Settings box is an icon with three lines. It is the Settings Visibility control. Click on it and set it to "All".

Some of the settings may still not be available. They might be for certain printers or materials whose definitions call for them to be visible, but most are there.

With a model loaded and selected - on the left side of the screen are a column of controls. The 6th one down is "Support Blockers". Select it and then click somewhere on your model and a 10mmm cube will be added. It can be scaled and moved. The button right above the support blocker button is "Per Model" settings. You can change the effect of the support blocker to change infill or other things at whatever location you want. Ya just gotta play around.

Here you can see seven of the eight support blockers I put in (they are the gray blocks). This particular model gets sliced twice. Once at .2 layer height and once at .1 layer height. The gcodes get combined so the base portion prints at .2 and the external threads on top print at .1.
