Any plans to support slic3r PE on PrusaPrint?

Are there plans to have slic3r PE pre-installed on PrusaPrint?

There is a plugin (https://plugins.octoprint.org/plugins/sl...) that allows the usage of slic3r and it would be awesome to have a fully remote, plug and play experience with PrusaPrint.

Answer this question I have this problem too

Is this a good question?

Hi Cassiano,

in the future it might, but our Slic3r PE is currently undertaking major code changes, so our devs need to finish it first. I will suggest to them your idea ;)

Awesome, thanks! That would be a huge win for PrusaPrint.

Hi Cassiano, after a brief discussion with the devs I learned we already tried. The current issue is the performance of the ARM boards. It takes way more time compared to the x86 platform. However, these small chips are increasing performance fast, so it might be powerful enough soon.

Ok, thanks for checking. I wonder how a Pi 3 B or B+ would fare against what you tested. It's quad-core and quite powerful for the size. Obviously not nearly as powerful as a lap/desktop PC but possibly enough with a bit of patience. :)

Our hardware was slightly more powerful than the RPi 3B, though the slicing times were 4x times slower compared to our laptops, which are mostly intel based i5/i7.

That seems like a reasonable time. Slic3r is pretty fast on the desk/laptop.

The convenience of being able to download an STL from the internet and just pushing that straight to Octoprint from any computer, phone or tablet and start printing straight away sounds like a huge win.

Certainly waiting a minute or two for a slice is, in many situations, a lot quicker and with less cognitive overhead than going to the computer where the slicer is configured with the correct profiles, getting the stl, slicing it, then finally uploading it to Octoprint and then getting back to what I was doing or where I was when I found the thing I wanted/had to print.
