As the title says, I have taken a linear rail out of a printer and it's just controlled by a dc motor, but I can't find any suitable tutorials on how to repurpose it. Does anyone know how I can control where the main cartridge area goes by controlling the dc motor? (I'm trying to make a drink dispenser so I need to put the cartridge holder thing in specific places).Thank you! via /r/DIY https://ift.tt/2VoE7LU
