I have a question. Home printers are controlled via open-source software such as Pronterface. These printers print mostly in plastic, but how to control the "metal" printer. The principle of the printing here is a little different. Is it possible to use, for example, Pronterface for this task or the completely different software is needed?
Pronterface would control the printer, but you would need a slicer that could give you g-code that works with said metal printer. Being it would be using metal, most of those are powder based, using a laser to sinter. The slicers for FDM based machines would not create the correct g-code for the application. I know there has been some effort around powder based printers (both metal and plastic) but I do not know of any software that has resulted from these efforts.
This wiki index for powder printers may be of some help to find out what software they are working on, most likely a custom solution. http://reprap.org/wiki/Powder
