Connection of the laser, 1 W and more (1000 mW) to a laser engraver, a CNC machine, a plotter (MakeBlock Plotter XY 2.0, DIY), and a 3D printer (WanHao, Reprap, Ultimaker)

Our customers often ask us how to connect a powerful laser to this or that CNC machine or plotter, if the circuit board of the device does not have a separate power supply for a laser, and the current going through the control board is minimal and does not exceed, for example, 0.5 A.

The DIY и MakeBlock engraver board is powered with 12V and 0.5-1 Amps, not more.

Remember that 1W diode (solid-state) lasers requireapprox. 1-2 А и 12 v current; 5 W lasers and higher need more than 3 A.

Our 8W (8000 mW) diode laser needs 4-5Amps and 12 volts.

To mount a more powerful laser on a plotter (such as a MakeBlock XY plotter 2.0 KIT) or on a small Neje engraver additional power supply is needed. It is possible to install a separate battery unit and a driver, for instance.

We share with everyone an open hardward schematics

Endurance circuit MO 1 schematics

Connect the laser control to the МК and GND1 pins. The supplied power must not exceed 24 v. Connect the laser «+» to «+12v», the laser «-» to the «Drain» of the field transistor.

The GND1 and GND2 contacts may not be necessarily located on the same line. It is possible to use the «+12V» and «GND2» contacts of the lead-acid battery.

It is enough to have a bread board of 20х20 mm to place all the elements.

This schematics furnishes

12 v lasers with the current up to 5 A.

Use the current powering the DIY or an additional battery unit.

The schematics connection

The laser «+» and «-» contacts are controlling and located at the top on the right-hand side of the circuit board picture of the NEJE engraver. Connect them to the «МК» and «GND1» contacts of the Endurance circuit MO 1.

You can put the Endurance circuit MO 1 board inside a telephone box. When choosing wires, take into account the current stregnth depending on the laser power. A 5.6 W laser draws up to 3.5 А. and 8W draws up to 5A.

Anyone can assemble it independently.

We are happy to share useful technologies with the community of laser enthusiasts and laser engraving fans.
