I’m having an issue with slicing an STL file I downloaded from Maker World. It looks like the STL file and the support structure already in place. But when I go to slice it the supports are not printed and I get a floating cantilever warning. If I try and add supports in the slicer, they are not added and I still get the same error. How do I fix this?
Can you post the link to the model…
The model can be found here:
But I think I figured out the problem. The supports in the model where just very thin. So the slicer was deleting them. I changed the Outer Wall Line Width to 0.25 and it look like it slice fine now. Also added some manual tree supports. I now just need to trty the print.
Let us know if that works, and what nozzle size you are using. It may slice OK with a narrow wall width, but I think you will need a 0.2 nozzle to print reliably. A 0.4 nozzle might work but the width might be inconsistent and it may not adhere to previous layers. I don’t think anything larger will work at all.
Yup, you are right. tried a couple times and quickly canceled the print. Going to try the 0.2mm nozzle next.
Did you check the box that says “detect thin wall” in the slicer?
Sometimes you can get away with this on a 0.4 nozzle if you use Arachne wall generator and a smaller “minimum wall width %” and “minimum feature size”. Arachne fluctuates wall line widths, while Classic keeps it constant.
History: Back in the day, precision of the extruders and motion systems weren’t so great and trying to flutter the wall widths just made them into spaghetti. The current generation of printers are capable of doing this well, so you can choose which strategy you want to use.
