Works best if your model is centered on 0,0. Not on your 3d printer bed, gcode files must be converted to a text file to be loaded into lists on scratch It’s quite slow because there’s a lot of processing involved, turbo mode helps but using turbowarp is probably a good idea: https://turbowarp.org/1043825173?fps=250&hqpen&interpolate&turbo
Remix with your own gcode, I’d love to see what everyone’s making. Scratch has a pretty small file size limit so I would recommend 0%infill and 1-2 walls Tutorial on importing G-code https://scratch.mit.edu/projects/1077944621/
