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.
