PrusaSlicer VS OctoPrint

I do this with my Prusa MK3S with MMU2S. It cannot be done without this fix in PrusaSlicer, however (which hasn't been merged into a release).

If you’d like to support my request https://github.com/prusa3d/PrusaSlicer/issues/11102 and leave a comment or a 👍. Any support is welcome and helps to get this feature implemented in PrusaSlicer. Thank you in advance!

That's it. I haven't seen many mentions of global variables other than This GitHub page from March so I hope this helps people.

Example: "The feature was ported from BambuStudio, thanks to @bambulab for the initial implementation." https://github.com/prusa3d/PrusaSlicer/releases/tag/version_2.6.0-beta4

It may be worth filing a feature request issue for your use case with the PrusaSlicer project.

There is an issue with PrusaSlicer that needs to be fixed to make it work for true multi-material printing. At this time, the nozzle can jam when switching from a high temperature to a lower temperature filament, because the purge is attempted at the lower temperature, which can cause the nozzle to jam. I fixed it in this PR (so that purging happens at the higher of the two temperatures) but it never got merged into the current release, and given the PR backlog, I doubt it ever will. In any case, that fix converts the MMU into a true multi-material printer. I can now print PLA with PETG supports, for example. Or mix PLA with PLA+. I have to use my own PrusaSlicer build to do this, however.

Hi, I have a project based on https://github.com/prusa3d/PrusaSlicer/tree/master that I want to create a .app for to try on another laptop. however i just can't figure out how. it seems like xcode build will do that for you, however upon using cmake with -GXcode it does create a project and I can debug/run my app with it. but there is no .app within the file structure.

The cheapest way is to use OctoPrint. Octoprint itself is free, and although it's often run on a Raspberry Pi, it can be installed on many things, such as an old laptop runing Linux or even Windows, or a small single-board computer. OctoPrint would connect to the printer using a USB cable, and you'd send the slicer output to Octoprint over your WiFi.

Octoprint

2023-11-08 14:10:57,263 - octoprint.util.connectivity.connectivity_checker - INF O - Resolving octoprint.org is working

- Two LibreELEC (https://libreelec.tv/) mediaplayers in house (yes, one is not enough in my big family).

- One for hosting low usage applications at home network (Unifi controller and some more).

- Octoprint (https://octoprint.org) connected to the 3d-printer.

- One on my desk for hardware hacking – mostly as just a PC with GPIO.

- Some Raspberry Pi Zeros as security cameras.

Really quite easy, especially if you have ever dealt with a raspberry pi before. Once installed & set up, you manage everything over a web interface. I even added a webcam to it in order to see what's going on. Check out https://octoprint.org/

For other devices it can be harder, there are guides for installing on Linux on the octoprint website (I use an old laptop running Linux Mint). If using an old Android phone look for Octo4A.

I’d just get Octoprint setup and a camera for it
