I’m brand new to laser cutting (bought a 100w red chinese laser from ebay) and lightburn as well. I have gone through all the lightburn video tutorials which have helped me greatly getting me into the process but I have a few questions.
To start, I am getting into laser cutting specifically to augment my other manufacturing pipelines for product prototyping. I am experienced with CNC’s, traditional milling and 3D printing so please if I am using the incorrect term for laser cutting let me know.
Are there any good rules of thumb for beginning speeds and power settings? Are there any resources that offer starting points for materials based off the laser wattage etc?
Are there any materials I should absolutely avoid and is there any online lists of these materials? I read that neoprene releases chlorine gas when cut etc and don’t want to inadvertently endanger myself or others.
Does anyone have any recommendations for source/brand of compounds that work well for engraving stainless steel? I’m located in the US midwest if that impacts your recommendation.
Thank you in advance.
