- Page 2 3 stepper motor drivers on an Arduino Uno shield. We recommend the usage of our Mr Beam grbl fork which is already configured to the shields features. You can find it at https://github.com/ mrbeam .
- Page 3 Laser diode driver The Mr Beam Shield features a dimmable and Laser Diode efficient laser diode driver with a maximum output of 1500mA. The output current has to be set before connecting a laser diode. Current Selector Check the data sheet of your diode for the maximum...
- Page 4 Power in The shield supports a wide input voltage between 12V and 24V. When using your own power source please check that the power jack has the correct polarity. Reset, Cancel, Hold, Resume Buttons For easy wiring the shield has a dedicated connector...
- Page 5 This allows to drive two steppers with a single driver and is useful for a double motor axis like the Y-axis on a Mr Beam Senior. The connectors are using the reprap-style pin Y-Axis order (1b, 1a, 2a, 2b).
- Page 6 Though the analog Arduino pins A4 and A5 are not used in Sensor 2 A5 Mode standard GRBL firmware, the shield is ready for future sense developments and provides own connectors for them. In combination with a +5v and ground pin for each, it is easy ground to plug in common sensors.
- Page 7 Laser Classification IEC 60825 classiefies laser products into different LASER RADIATION DANGER AVOID EYE OR SKIN EXPOSURE TO categories depending on light emitted, wavelength and eye DIRECT OR SCATTERED safety. Classes for typical laser diodes are given below. RADIATION LASER RADIATION CLASS 4 LASER PRODUCT LASER RADIATION AVOID EYE OR SKIN EXPOSURE...
- Page 8 Usage Additional Information Resources The shield was designed to be used with the popular grbl firmware. We The internet is full of information about laser technology and safety. recommend our own fork at https://github.com/mrbeam which is Some (but not all) information resources are listed below: preconfigured to the shield's pin layout and features.
