Use:
When the laser driver board is powered for the first time, every use, the reset button must be pressed.
Insert the safety key, turn on the power and press the rest button. The fans should both come on along
with a green LED indicating the driver board is ready for use.
Vector Gcode can be created in the same fashion as we create routing Gcode. A spindle speed of 4000
(lowest setting on most our products) will be the minimum power. A spindle speed of 12000 will be
maximum power.
Raster jobs are best created by other software than the ones we use for routing gcode generation. They
provide more efficient code.
Once gcode has been created, load gcode into your communication software, such as CNC.js or bCNC.
Locate the serial port box, in CNC.js this is the black box in the middle of the left-hand side of the screen.
bCNC this is the upper right-hand corner of the screen, a tab called terminal.
Type $$ and hit enter.
Note that $32=0 currently. Router control is standard in this mode. Type $32=1 and hit enter. The
machine is now in laser mode.
Making this setting change turns off the spindle power, hence the laser power during G0 moves and
enables during G1, G2, G3 moves.
As an example, in code G0 X1 Y1 Z1 the laser will be off moving or rapid to this location. The next move
F600 G1 X2 Y2 Z2 will turn on the laser and move to this location. The next rapid of G0 will turn off the
laser.
The power of GRBL allows the use of standard routing gcode to be used in this method without the need
for special commands to operate the laser.
