Many types of CNC machines and 3D printers with different control voltage standards and levels available on the market may be used to control the PLH3D head. The PLH3D-CNC Adapter converts all these signals to the standard compatible with the PLH3D head. The PLH3D-CNC Adapter contains widely-used, industry-standard screw connectors. A dedicated, low-noise desktop power supply unit assures compatibility and reliability as well as eliminates problems caused by using third-party power supplies.

EXTERNAL SWITCH Connector Pinout and Description Pin no. Name External switch Switch A Switch B The switches are connected in series with the arming relay and feed the power supply to the laser head. Opening any of the switches disconnects the supply of the laser head and thus disarms it. Connect the first switch to A.1 and A.2, and the second switch to B.1 and B.2.

Enable Options Some CNC machines issue special “disable/enable” signals for turning the laser beam off/on. The PLH3D-CNC Adapter can be set in such a way that the laser beam is enabled only at certain states on two Enable inputs and disabled in other cases.
Turn the key into the upper position. The power supply unit is not attached either to Plug in the power supply. the mains (wall) or to the PLH3D-CNC Adapter. There is no mains supply (grid power). Check the mains supply (grid power).
