This is a video that describes the installation of a Super PID CNC Router Speed Controller on a ShopBot PRT 48 X 96 CNC Router. This unit allows lower RPM's for your Router (i.e. 5K). That is good news for those of us that need to machine acrylic at lower RPM's to keep the material from melting during machining operations. This unit provides constant RPM's with good torque at all RPM ranges.
Nice enclosure! Hope it makes cutting other materials easier, like it has for me...
