The laser pointer tool is used to provide a reference point to zero your X & Y axis.
Selecting a point on your stock and zeroing your X & Y coordinates will automatically transfer them to the other spindles on your machine.
The Dry Run laser pointer can be used to do a dry run of your machined part to ensure that it will fit on your stock.
While performing a Dry run of your Gcode file it will ignore Coolant on / off Gcodes as well as tool changes and changes in Z axis height.
A TTL output can be assigned to turn the laser pointer on and off and will automatically turn on when the Laser pointer is selected. This can be done using a MASSO relay module if needed.
Laser pointer Output
The Dry Run Laser pointer
The Laser for this is a small low power laser typically 5mW or less and may be a spot or cross hair as required. In general the lower power the laser is the easier it is on the eyes to view however this must be balanced with ambient light levels.
Connection and configuration
Configure a TTL output as a Laser Pointer On/Off
Wire as per the diagram below. Ensure that you provide the correct voltage to your Laser or you will damage it.
Enter the X & Y Offset value from your main tool that you will be using as a reference for the machine. This is usually the Main Spindle, Plasma head or WaterJet head.
All Multi-head offsets must reference from the same tool.
Example wiring diagram
WARNING: The example below is intended to illustrate the concept of how such a system could be wired. The actual wiring of your machine will depend on the hardware used and it's requirements. Please consult your user manual for the correct way to wire your selected hardware. If unsure please consult a qualified electrical engineer to assist with wiring of your machine.
Using the Dry Run Laser Pointer
In MDI select Dry Run This will Automatically turn the Laser on and put MASSO into Dry Run mode.
While in Dry Run Mode the Dry Run Mode icon will flash on screen.
While in Dry Run Mode the Spindle will not start, The coolant will not turn on and the Z axis will not move under Gcode control.
You can use the laser to Zero your X & Y axis if desired. When you leave Dry Run mode the coordinates will be offset with respect to the new selected tool.
You can load your Gcode file in Dry Run if you have not already done so.
Run you Gcode File as required. The laser will show the how the tool path will go when you machine the part.
To Exit dry Run Mode Press the Dry Run Button and the laser will turn off and you will return to the previous tool.
There are no dedicated buttons on the F2 Screen associated with this tool.
