Prusaslicer Support Settings

Jasers

Looking for guidance regarding organic support settings in prusaslicer. I've utilized the default settings with the obvious removal difficulties one experiences. I've been adjusting per recommendations on fosscad but just can't seem to dial it in to my satisfaction even though parts are serviceable. I know it can be better (performance/ease of removal) and I'm running out of ideas. Anyone willing to share support settings that have worked well for you in PLA Pro and PET CF? I'm using Prusaslicer and printing with MK3S+.

I've actually had really good results with some of the default settings. Make sure that you are using a couple layers of top interface material, and that the XY offset is at least 60% or 0.25 mm.

What parts of the support have been hard to remove?

Mainly bits of the interface layers are sticking. I have XY set to 75%. I tried increasing Z sep but found that although support removal improved, print quality suffered. Don't get me wrong, my prints are serviceable, just wanted to explore what others have experienced. I've seen some videos of supports that seemed to break away easy and leave little trace of their existence, so I thought there must be a better way.

Jasers Using a razor to pick off some of the interface is normal, but should not be a lot of effort. Good layer adhesion will result in harder to remove supports. Increasing cooling for bridges could make the interface adhesion a bit lower, assuming it's not already at 100%.

hoffmantactical Reset to Prusa defaults and tweaked only the XY distance and double checked cooling. You were spot on, close to default settings and increasing bridge cooling did it! Thanks Tim.

I’ve been printing with various types of pla lately and Pla pro has always been tough to remove for me. Normal pla and polyterra have been much easier but pla pro is just way chewier and doesn’t break away like I want. Usually the bottom interface but both can be difficult. Snug supports seem to be easier for me but don’t apply to every situation. Idk if you can use different support types for different areas but I may try that in the future.
Another idea I haven’t tried is turning up the print speed for the support layers which could decrease adhesion as well.
Interested to hear back if you find something that works. Try YouTube also I haven’t watched it yet but saw a video about the this exact topic yesterday. Being able to change temp for certain areas would be an interesting ability 🧐

Changing temp by the layer is pretty easy to do with a custom Gcode command, but doing it by extrusion type would be tricky. Might be able to trick the printer into thinking it's an IDEX.
