Additional power supply laser driver for CNC machines, plotters, 3D printers

Endurance MO1 PCB

Additional PCB – Endurance MO1 to connect a laser to CNC machines, XY plotters, DIY engraving machines and 3D printers

To install a powerful laser onto a CNC machine, plotter or any device of this kind, it’s necessary to have a bigger amperage; thus, for 5.6W and 8W lasers you need 4 and 5 Amps, respectively, and 12 V.

Not all the controllers (control boards) have the corresponding outs. Usually they have 1-2 Amps and 12 V.

A question arises, how to connect a powerful laser if there are no corresponding out connectors.
You just cannot take an additional power supply, as you must also have a tool for turning the laser on/off and a mechanism to adjust the power of the laser.
Endurance MO1 PCB

To solve this problem we have designed the Endurance MO 1 board.

The principle of its work
The controlling current of many CNC machines is too low to run the laser. At the low input current you can raise the output current up to 5 Amps, and that will make it possible to power the lasers with 5.6W and 8W outpup.

Components
This board consists of a powerful field transistor, an opto coupler and resistors.
