In progress! I got a Quad II pick and place machine for a steal on EBay. These are professional machines, so the mechanical hardware is far better than most "benchtop" or hobbyist pick and place machines. Because this machine was "new" in the '90s, it needs a new controller and vision system. I have been working with jamelofs to port the STM32 port of RepRapFirmware to the STM32MP157 so that the Cortex-M4 can be used for motion control and the Cortex-A7 can be used for vision: RRFBuild for STM32MP157
