Issues and Tips When Using Slic3r with Repetier-Host

Hi everyone,

I've been using Repetier-Host in combination with Slic3r for some time and wanted to open a general discussion around it — both to troubleshoot a few issues and share experiences.

Some of the things I’ve run into:

  • Slic3r sometimes fails to slice models with certain geometries that CuraEngine handles fine.

  • Profiles can be tricky to tune — small changes to layer height or extrusion width occasionally cause unexpected results.

  • Repetier-Host doesn’t always reflect Slic3r changes immediately, especially when switching between slicing engines.

On the flip side, I appreciate:

  • The level of control Slic3r offers — especially with infill patterns and support material.

  • Seamless integration in Repetier-Host, once it’s dialed in correctly.

  • G-code preview and multi-extruder support.

I’m curious:

  • What have others experienced when using Slic3r in Repetier-Host?

  • Are there known issues or workarounds for better performance?

  • Any tips for profile management or advanced features that are easy to miss?

Looking forward to hearing from the community!

  • Better switch to PrusaSlicer which is still actively developed and can be seen as successor of Slic3r. More features, faster, ...
  • Thanks for the suggestion! I’ve looked into PrusaSlicer before but haven’t fully made the switch yet — mostly because I’m pretty comfortable with the Slic3r workflow inside Repetier-Host.

    That said, I’m definitely open to giving it another shot, especially if it solves some of the slicing quirks I’ve been running into. Does it integrate well with Repetier-Host these days, or do you mostly use it standalone?

    Appreciate the tip!

  • I meant the bundeled prusa slicer in host. Same workflow with that.

    Okay. I just want to learn something personal about you — if you're okay with that, may I ask?
