With 3D printers like the Open-5x or tool changers (e.g. Prusa XL) both, 5-axis simultaneous 3D-printing as well as hybrid manufacturing (additive followed up by subtractive), is more accessible than they ever were.
For those already venturing into this endeavor: What is your toolchain/software?
Currently, I finish the additive/3D print before running a second gcode for the subtractive part (contact surfaces, threads, …). This is far from an efficient and powerful process.
This doesn’t solve your issue but can’t you at least merge the gcode files so you only have to start the entire process once?
What I would like to see is a far more advanced solution where you could for example machine features which will be inaccessible once the print is finish.
Right now the tools for none industrial machines are basic as it feels like you are feeding a slicer output to a CAM package but the slicer isn’t designed with this in mind (e.g. printing certain features that will be machined lightly larger and everything else at normal size).
this was gonna be my thought. writing a python script to append one file to another is pretty easy
