RE: Support problem

Nothing attached.  You have to ZIP up files for the forum to accept them.  If you don't it just silently drops them.  Its also best practice to check your post immediately after hitting Add Reply as the edit window is only a few minutes long.

Hi Danny, 
I think the first error is not succeeding on adding Pictures... 

In Windows, I Open a reduced size file manager window, over the forum page and drag the images into the bottom of the text window.

Support problem 20250309_174526

Second attempt to add files.

RE: Support problem

I wish you had included a zipped up Prusa Slicer project file too as well as the pics.  That way we could examine all the settings and would have a complete picture.

btw pics are one of the few things you don't need to zip up 🙂

Without a project I'm guessing you have Dont Support bridges enabled.

Personally Id suggest switching your options to For Support enforcers Only and then manually paint in spots along the bridges and other overhang areas to get supports placed exactly where you want them.

If you do decide to attach a project we can also help with how to do that if you aren't familiar with the tools to do all this.

RE: Support problem

Hereby the project file.

RE: Support problem

Yeah, as Neophyl's spider sense indicated, you have Don't Support Bridges active.

I didn't look at other settings but I just couldn't get over all the supports. I think most of the beams going across will look awful after removing the supports unless you have an MMU or XL and can print with a different support material. My suggestion is to cut the model in half in the vertical direction, using Prusaslicer's Cut function, flip the top part so both parts print with their legs sticking up. No supports needed at all anymore. Of course you have to connect the two pieced (super glue) and/or utilize Cut's ability to add connectors.

RE: Support problem

Thanks for the advice. I wasn't awhere of this.

RE: Support problem

Try this version of your project.

Your cross members should look alright with this method and will probably only require minimal post processing.

Its a pity your printer doesn't have more height.  Could have almost eliminated support then 🙂

RE: Support problem

Ran out of edit time.

With more height you can try even more unconventional orientations.

RE: Support problem

I'am a bit of a newby and didn't realyse that is also possible this way. Thanks for the advice.

RE: Support problem

I'm getting vertigo just from looking at it 🙂

Tilting an object is a good strategy for minimizing supports. For this one though, I'm not sure I'd trust my Mk4S with vibrations at higher layers and the small contact area. Would probably add some support pillars around the outmost vertices. But I think this model is a good one to explore different options.

RE: Support problem

Yeah I’d hesitate to actually print that with that orientation with a bed slinger. I ‘might’ with a fixed bed core x y though. It was more of an example to show that looking outside the norms can be beneficial. 

RE: Support problem

I am using a CR5 PRO H so I'll give it a try. Thanks.
