Some materials can release harmful chemical vapors and should not be laser cut. Be sure to look up the MSDS for your material before cutting it. If you're using a new material that does not yet have suggested settings, look up suggested settings for similar then play around with the settings to find what works best. For example you wouldn't want to cut cardboard on the same settings as you would a piece of. These are generally guidelines rather than rules and you may need to adjust depending on material inconsistencies or personal preference. There are recommended settings for getting the best results different materials. Gemini 1.0 Ultra surpasses state-of-the-art performance on a range of benchmarks including text and coding. This is helpful if you want to go over the raster or cut paths on your design more than once. Gemini is the first model to outperform human experts on MMLU (Massive Multitask Language Understanding), one of the most popular methods to test the knowledge and problem solving abilities of AI models. Their software allows you to adjust the speed, frequency and power of the laser beam as well as whether you want to run a vector (cut), raster (etch), or both file. Most laser cutters use a separate software to adjust settings. Some materials cut easier, some etch easier and others won't cut or etch at all!
