Strange behavior of the Pattern Spacing #4053

Closed SteWhite closed 4 years ago

SteWhite commented 4 years ago

Version

2.2.0

Operating system type + version

Windows 10 pro 64bit

3D printer brand / version + firmware version (if known)

Anycubic i3 mega-s

Behavior

If I change the pattern spacing, a part of the model is no supported.

Is this a new feature request? no pattern spacing 5

Project File (.3MF) where problem occurs

supporti errati.zip

neophyl commented 4 years ago

The support is supporting the overhang perimeters. Once the perimeters are laid down the other interior area is printed using bridging so doesn't need to be supported. When the spacing is smaller it has more 'definition' so it can follow the unsupported perimeter, when larger it treats the whole area as one section.
Seems to be doing exactly what I'd expect.

Thanks for the reply. (the orientation is for the example) With 2.5 I don't have that any hole/bridge. With 2 i have 8mm hole/bridge It's inconceivable. I have never seen Simplify3D think in this way. I print often with nozzle 0.25 and layer 0.05 and I cannot cover up a 8mm bridge. Mayby the MK3s can (in few weeks I will find out) but with anycubic it's impossible. pattern spacing2

and I cannot cover up a 8mm bridge.

Disable "Don't support bridges" setting. It should solve your issue.

SteWhite commented 4 years ago

ok perfect!! Sorry, I'm blind. Do you know how can I reduce the extra inflation distance? With "support enforcer" it's the same. Thanks a lot! pattern spacing3

rtyr commented 4 years ago

There is no special setting for extra inflation distance. I guess you can avoid this by different pattern spacing or by increasing XY separation. Or enable "Support on build plate only" :-).

SteWhite commented 4 years ago

yes, I have tried that features, It partially solves the problem. Thanks a lot.
