My printer is ANET A6, I know it is out-of-dated. Bofore connecting it to my loptop with latest Pronterface, I'd like to know, whether Pronterface or simply sending commands from the GUI makes sense with the old device? The only available USBasp seems dedicated for burning fireware / bootloader. Does anyone of you have experience with the old board ANET3D V1-5 (ATmega1284P)?
