If your laser has an enable input you can connect an Estop relay to your Laser to disable it in an emergency. The Laser module board would commonly be found mounted on top of the Laser itself with or without a fan as shown below.Įnsure that the wires carrying power from the laser power supply are correctly sized for the required current.
#SUB ZERO LASER CUTTER DRIVER#
The image below show several examples of typical driver boards. It is common for a Laser unit to have only 3 terminals Power, GND and PWM and this is a common configuration with most lasers. Here it has been put into clear heatshrink.
It is a good idea to insulate any resistor mounted in this manner to avoid accidental contacts.The resistor can be installed at the Laser or directly on MASSO as shown below.If you are unsure if your Laser has a pull down resistor there is no disadvantage in adding the resistor.This is needed for correct PWM operation.The 5.6K resistor installed between the PWM output and MASSO GND is important and must be installed on all Lasers that do not include a built in pull down resistor.Information on how the Laser used in testing can be found here: Opt Lasers MASSO uses TTL only and controls the power of the laser using PWM.
#SUB ZERO LASER CUTTER MANUAL#
please consult the user manual that came with your Laser to establish the correct connection. The connections shown below are for demonstration purposes only. If you are unsure if your Laser has a pull down resistor built in there is no disadvantage in adding the resistor. This is needed for correct PWM operation. The 5.6K resistor installed between the PWM output and MASSO GND is important and must be installed on all Lasers that do not include a built in pull down resistor. How you connect your Laser will depend on what type of Laser you have and it's interface.
When the Laser Tool 111 is selected the display automatically changes to show Laser related information. To change between 2D View and Depth Map view press the button at the top right of the display area. For a Grayscale engraving to be able to be viewed as Grayscale, the Gcode file must include T111 M06 at the start of the file or the Depth Map view will be blank. Offsets are only needed when switching between the Laser and other tools and only if they are part of the same Gcode file. 
It would not be uncommon to leave the Z offset set to 0 and to manually zero the Laser when doing the job. The Z offset will be determined by the focus point of your Laser offset to the Z zero point of your Spindle tool. This can be measured zeroing the DRO's, making a spot with the Laser and then jog the Main spindle over to the center of the spot and reading off the X Y Y coordinates on the DRO's.
X,Y & Z offset is the distance from the Main spindle or other Main tool if using Waterjet or Plasma. Since power is controlled by turning the Laser on and off very rapidly, if you have a low PWM frequency and move quickly you could get a line that has areas where the laser was on or off - A frequency of 10Khz should be a good balance. It is recommended that you select a value of 10Khz though this will depend on the power of your Laser and the maximum feed rate you will be moving at. Go to the Multi-Head setting page and select Laser Engraving/Cutting. An output can be assigned for Air assist is required. An output can be assigned to move the Laser into position when Laser is selected. No other output can be used for this function as it includes special hardware to output a PWM signal. Configure MASSO output 11 for the LASER Engraving/Cutting output as shown. Safety glasses suitable for the laser you are using. Move to X0 Y0 at a feed rate of 600 with Laser intensity of 0% PWM (off). Move to X100 Y100 at a feed rate of 600 with Laser intensity of 35% PWM. Move to X100 Y0 at a feed rate of 600 with Laser intensity of 35% PWM. The S command must be included with a G1 and is synchronized with motion. S - This controls the Laser PWM using any number from 0 to 1000. 0 is 0% and 1000 is 100% power. M03 - Turn Laser on This turns the laser Engraving/Cutting output on with 0 intensity. To change to Laser mode you need to load Tool 111 T111 - Laser is defined as Tool 111 and cannot be changed. When working with Grayscale engraving MASSO can display the image by using the Depth Map feature. This will allow the Laser to be used for Cutting, General line engraving, Dithered and Grayscale engraving. MASSO can turned the Laser on and off as well as control the power of the Laser using PWM. This feature allows you to add a Laser to MASSO to use for engraving or cutting as required. #SUB ZERO LASER CUTTER SOFTWARE#
INFORMATION: This feature is only available on MASSO G3 & MASSO Touch version 5.0 software or higher
