I really wish we had open source 2D printers like we have open source 3D printers. That could solve a lot of the problems I think as we could have an open spec to allow people to do whatever they want. My Prusa doesn't care what brand filament I want to use, just as long it can drive it, melt it, and lay it down the way I need. Also why is it my 3D printers are more reliable than my 2D printers most days?
