bug reports should be made on the github issue tracker here: https://github.com/FreeCAD/FreeCAD/issues

• Marlin

  755 15,919 9.8 C++

  Marlin is an optimized firmware for RepRap 3D printers based on the Arduino platform. Many commercial 3D printers come with Marlin installed. Check with your vendor if you need source code for your specific machine.

  

Project mention: Why Prusa is floundering, and how you can avoid their fate | news.ycombinator.com | 2023-12-26

There is _a lot_ wrong with Marlin. It is a complex codebase, full with ancient artefacts, litterred with preprocessor ifdefs every 2-3 lines of code, dynamic includes in the middle of CPP files, etc[1]. It's about as unreadable as C++ code gets--well, I guess it's not template metaprogramming.

Klipper by contrast is a breeze to read through[2].

I am very grateful for Marlin, for all of reprap, and everyone who has contributed to it. But saying there is nothing wrong with it is straight up misguided.

Project mention: X Max 3 owner for the past 4 months and it has been a headache | /r/QIDI | 2023-12-10

You might also try a different slicer. I used Qidi Slicer for a couple prints but found better results from Orca Slicer and haven't looked back. You might find that Orca works better for your PETG projects. It also has calibration functions for helping set the flow ratio and pressure advance (https://github.com/SoftFever/OrcaSlicer/wiki/Calibration).

Project mention: Dust3D – Low Poly Modeling Tool | news.ycombinator.com | 2023-07-02

I wonder about the state of the project. I found it through HN in the past but the author seems to be busy rewriting the project

• sv06

  18 118 2.6 C++

Project mention: First layer issues. Leveled bed, trammed x axis. SV06 | /r/FixMyPrint | 2023-06-01

There is also a software solution. If you are running the stock firmware, flash a version of Marlin with Unified Bed Leveling (UBL) enabled. It will let you use the bed sensor to build a mesh, then go through each point and manually adjust it as needed. You can either compile it yourself or just use the UBL version from here: https://github.com/hillsoftware/sv06
