I think the operative word here is "free". We have a full-featured G-code editor for sale, but it took us over three years to write it. I don't know what planet you live on, but three years to develop a product means that you've got to SELL hundreds, maybe thousands of them to recoup the cost. Working for 3 years for free is 3 years I can't spend with my family.
