Soldering Robot First 40 pin soldering run

This video shows the first full run of both soldering irons on our diy soldering robot project soldering a 40 pin header on a Raspberry Pi expansion board. The speeds are set low at the moment on the stepper motors so we can make any position adjustments needed and once we are happy with the soldering placement we will work on making the machine faster by increasing the element temperature and the solder feed rates. More details about the project are on my blog at
