Printing support material inside my infill

[bwturnbull]

I just upgraded to 3.0. I am excited to see the new infill options. I just tried reprinting a model that I've successfully printed almost a dozen times now, and all of a sudden I am getting some unique problems.

When I print support material to support overhangs on the outside of the part, it continues to print support material straight through the walls and the infill of my part. Why would I want my infill to be filled with support material? I have tried different models, different infills, different support setups, and I always get this. Even when I click support "From Build Platform Only", it fills the inside of my part with support material. I never had this problem in Version 2.2.

Does anyone know why this is happening? I was able to recreate the problem by using a simple box with an overhang on top.

This may be related to the problem I'm having with supports being embedded in the walls of my dual extrusion prints. In that case I don't think the supports actually were being generated by the tool paths but I was left with a lot of spurious supports outside the part not supporting anything.

I submitted a factory file to support yesterday but haven't heard back yet.

Yeah, I just noticed the same thing while trying to print out a doughnut. The thing just creates support inside the hole on its own, even when all support and raft options are unselected. Should not need any supports for this model, since it is split right in half. I think I'm gonna return to 2.2, which actually was better for the parts I'm printing.

Can you post a factory file?

Here is a factory file containing my process parameters. The model is just a box with an overhang on top. https://dl.dropboxusercontent.com/u/120 ... or.factory

I just downloaded version 3.0.1, and it seems that my problem has disappeared. Even the factory file that had errors in 3.0.0 now loads correctly. I don't know what the problem was, but I guess they fixed what ever was causing the bad path generation.

Hello,

have the same problem with 3.0.1.

DaVinci 1.0A

When I start a new process, everything works fine (Slice02).

Correct

I printed the model. When I change parameters, e.g. speed from 30 to 35, the new print preview shows like slice01.

Incorrect with support

I am no more able to remove this unchecked and unwanted support.

I have to start a whole new process and make all my changes again.

Even restart does not change the behaviour.

I would recommend going to Repair-->Identify Self Intersecting Surfaces and also Identify Non-Manifold Edges. If either of those produce error, I would look to use this website to repair the model: https://modelrepair.azurewebsites.net/ which has worked really well for me.

It's not relatetd to any specific object.

Just tested some others while no errors where produced.
But same strange results.

When I set my process settings fresh from the profile and hit "prepare to print" - it works just fine.

But at any point later, I want to change some settings, holes are closed with support - not starting at the first layer.
See this screenshot, when printing "support" starts.

Those holes are supposed to be open - and printed just fine before just changing temperature from 190 to 185
