IdeaMaker Supports so close together?

My brand new stock N2 can bridge about 50 mm without a problem, so why is the IdeaMake auto generated supports so close together?

Both methods to auto-generate supports (interactive or slicer), default to really close together supports. I am looking into more control using the slicer method.


Looks like if I switch from Lines --> Grid and infil % from 30% --> 6%

Then I get more of what I am looking for

P.S. Using the interactive method has anyone found a way to lasso multiple supports for deletion or do we have to click on each one to delete it?

I'm so sorry, but if you refer to the support pillars in Manual Support, you can only delete them one at one time with one click.

My supports testing above miserably failed because my Horizontal Offset was still at the default 0.75 mm.

Here are the new supports settings I am testing.

Makes a support grid about 10 mm apart. Anyone else have any luck with different styles of support structures?

fwiw I always place supports manually, EXCEPT for large flat areas, since it is so dependent on material temperature and geometry

Here is what I have been doing for a few years. Using grid style supports instead of a raft to cut down on the amount of filament printed and using elephant feet to really attach the corners to reduce warping. Less filament, easier removal, less warping. Just cause I can do it on another 3D Printer doesn't mean I can do it yet on the Raise3D, but this print worked nicely. Just have to wait until Monday to see if it detaches easily.

The full print is a case for the Raspberry PI 3 with touch screen.

So I know now why the supports are so close together. When the supports are far apart like when using my grid technique the bridge part has lots of stringy bits for it's bottom layer. With really close supports that is not a problem. For my situation in which are are making prototypes the low quality is fine since it shows if the part works and it ups the speed and reduces the filament waste.

My build above came off the buildTac great but was really hard to remove the supports. I have done another build with the supports 2 layers away and I will see how that works.
