PrusaSlicer 2.2.0-alpha4 - Interesting internal bridging  

RE: PrusaSlicer 2.2.0-alpha4 - Interesting internal bridging

3MF project attached for anybody wanting to experiment. For some reason, the cut die is now bridging just like under PrusaSlicer 2.1.1, so I'm really puzzled as to what's going on.

Edit: Just realized the STL from Thingiverse has the sacrificial bridge built in... but it disappeared when I cut it apart. Now I'm really puzzled.

RE: PrusaSlicer 2.2.0-alpha4 - Interesting internal bridging

Here's the 3MF with the disappearing bridge. I only cut the part and this happened. Have not been able to replicate this though. I suppose it's technically a bug in 2.2.0-alpha 4, but not sure what triggered it.

RE: PrusaSlicer 2.2.0-alpha4 - Interesting internal bridging

Can we use a modifier to create internal bridging like in the model?, this could be a very handy feature.

And, maybe I just don't know how or it does not exist yet, when I slice a model I check the layers in the preview for any issues, this usually involves zooming in and tilt / rotating the view, is it possible to pan the view? as this would be very handy indeed and allow for some good fine tuning of settings / supports etc etc.

You can use a modifier and set it to 1 layer height and place them where you want to fill in areas yes.

As for panning, while its not quite perfect yet the recent added support for the 3dconnexion space mouse range allows that sort of movement as its a 6dof (6 degrees of freedom) input device.

You can also right click and drag to pan around an area too.  The one function that is lacking is a sort of xray mode, which would be useful in allowing placement of modifiers inside of models.  At the moment its a bit hit and miss and you can lose sight of small modifiers inside a model completely.

Might just go add a feature request for that one 🙂

Doh - Didn't think of using right click, and Hooray, I have a space mouse 🙂

The X ray feature, do you think it could work by using transparency for the existing model? 🙂

Thanks.

Always willing to pick up new tricks with Slicer, is there already some form of transparency for models that I've missed ?

RE: PrusaSlicer 2.2.0-alpha4 - Interesting internal bridging

Maybe you cut to a ½ layer? The bridge might not be realized when it is not a full layer thick.

Try to switch to 0.1 layer height and look if it is back.

No, that's my suggestion, if your already putting one in for X-Ray, then suggest variable transparency as this would help with placing modifiers.

And where do you put suggestions in?.

That's what I mean by x-ray anyway, not to be confused with wireframe :).  So it would also help with duplicate part placement as it would shade darker where parts intersect, you would be able to tell that parts were duplicated.  

You just add them to github same as a normal bug report.  Every so often one of the devs goes through and adds tags on to issues.  I've already added it over there but if anyone wants to pile on and raise its profile as 'a good idea' feel free 🙂

Great, I will look into this tomorrow now, have to be up very early, and the printers still got 1Hr 35 to finish, I hope I can sleep.

Finally building a LACK enclosure.

Should have used a 0.6mm nozzle.

RE: PrusaSlicer 2.2.0-alpha4 - Interesting internal bridging

I pretty much leave the 0.6 nozzle on my heavily modded direct drive cr10 now for 'draft' and quick prints and use the 0.4 on my mk3 for ones that need the better quality.

I built the enclosure when I first got my mk3 but I was looking at a remix that has doors that you can open up and then slide inside to get them out the way.  Useful when you need to leave them open for pla prints.  Cant seem to find the time to reprint though lol.

Thought that might be it, but the cut part has a good gap between the print bed and underside of the top surface.

Try to switch to 0.1 layer height and look if it is back.

I can't seem to re-create the effect that caused it to disappear. At this point, I think it was just a glitch. I was hoping there was a "bridge small openings" feature I'd missed, but it doesn't appear so.

Oh, a bridge small openings (possibly with an adjustable threshold) feature would save me a bundle of time adding flattened cylinder parts to my prints to manually bridge vertical screw holes. A concept that I picked up from Makers Muse (I think...) and applied with the PrusaSlicer toolset.
