This video mainly demonstrates how to install the feeder extension board onto our TronStol A1 pick and place machine. The installation of the feeder extension board is mainly to meet the use function of the non-standard material tray. During the installation, you can first use a screwdriver to remove the fixed shaft of the tray, then you can put the screws from the bottom to top into the two holes of the extension board. Then, use two nuts to fix the board and lastly tighten the screws with the screwdriver.
