Printing Custom 3d Model G-Codes from Grasshopper(Rhino 8)

Hi guys,

Recently i’ve been trying to write my own g-code (except the start & end code given from the bambu studio as almost presets) for 3d models like this.


(Not trying to use the existing slicing method, for design purposes & trying to control the toolpath of the printer to go more than just printing on flat xy planed layers.)

I’ve studied that i’ll need the start code - 3d model code - end code to make the gcodes work from a book called ‘Advanced 3d Printing with Grasshopper’, from Diego Garcia Cuevas and Gianluca Pugliese. And the codes they make could produce things like these.

I’ve tried testing with Creality slicer and Cura Slicer, and they work just fine but for the bambu studio, when i drag & drop the G code, it kind of works (like this in the image)

but whenever i try to print it,

And one more thing that i’ve tried is printing the gcode file directly from the sd card. But in this case, the nozzle and the bed starts to warm up, and the extruder moves but the filament won’t just come out.

(as the gcode is a bit long, i’ll leave a link for the code that i’ve used just in case for testing.)

If anyone had these issues in the past and solved it, could you please tell me how you made it work?

Thank you so much for your response in advance.

Welcome to the community! Your question seems quite specialized, and this forum may not have many users with the right expertise to provide a detailed answer. Additionally, since most discussions here happen in English, posting an example in Korean could further limit the number of people who can engage with your question.

To improve your chances of getting useful responses, I’d recommend providing your example in English. That way, more members of the community—including those who might have the expertise you’re looking for—can understand and contribute.
