Laser cutting control is provided within myCNC software.
|8119||Setting up the PWM frequency to control modulation|
Writing a value to the Global variable register from Hardware PLC procedure will change Frequency of PWM outputs. This option available for special edition of the myCNC-ET7 control board.
A table below shows PWM period depend on 8119 register value
|8119 value||PWM period|
The Laser Control settings window (Settings → Config → Technology → Laser control) allows for fine laser control at different speeds. This allows to prevent overheating when approaching corners, etc:
The following settings are available:
The myCNC Team provides the experimental laser cutting profile Y1366L on request. Note that at the time of writing the manual (November 2021) the profile is currently under development and is not yet intended for final release.
The main profile screen is displayed below:
The profile allows to select the following:
The profile also allows to use up to three pierce steps, and store up to 8 presets for laser cutting.
The modes can also be switched using the G130 command, for example:
G130 P1 G130 P2
The profile utilizes the following global variables:
|GVAR_LASER_PRESET_SELECT||8470||Load a set of parameters for the corresponding preset number|
|GVAR_LASER_PRESET_SAVE||8471||Save the current parameters as a cutting preset for the specified number|
An example of myCNC controller being used on a laser cutting setup can be seen below:
