I have / like my 3D printer, but... At present I go to sites like Thingiverse where I can (normally) search for / find a .stl file to download that describes an object that I want. My 3D printer wants to see a .gcode file which describes what path the 3D printer's print nozzle should follow (ie: devil is in the details, a perfect .gcode file for a Brand A printer could cause problems for a Brand B printer). Okay, there is software available that will take .stl files and convert them to .gcode files while taking into account the ... quirks ... of different printer makes/models. For the last while I have been using the program "Slic3r" to do this .stl to .gcode conversion, because it is good, fast, easy to use, and free. Problem, in early August I moved my main desktop PC from Debian 12 to Debian 13 and the "Slic3r" program isn't available in the default Debian 13 repository. Also I have been unable so far to get the "Slic3r" flatpack file to run, all meaning getting "Slic3r" to run on my desktop machine will be no joy :-( . I have tried to find another .stl to .gcode conversion program for my main machine, so far without success :-( . My solution while not perfect, does work is to put one of my Raspberry Pi 5's to work, running "PrusaSlicer"... I'll do the grumpy old guy thing of noting I'm not super keen on the differences between "Slic3r" and "PrusaSlicer", but ... better a working but flawed (or at least different) ... software tool than no software tool.
