+ | ====Other tools==== | ||
+ | |||
+ | The X1366V profile allows for tangential cutting control not only with a simple cutting knife, but a variety of other tools such as a half-knife, creasing wheel, 45 degree knife, and more. Tools can be combined into a single job by importing a DXF file with pre-defined layers which will be assigned to different technologies. If a tool does not require tangential cutting control (such as a spindle), it can also be defined in the myCNC software to be assigned to a separate layer/pen in the DXF/HP-GL file respectively. | ||
+ | |||
+ | The important part about tangential cutting control is the ability to use the rotation axis (axis C in the X1366V profile). This is turned on by the following code that is included in the M6 macro (the M6 macro is responsible for switching between the tools): | ||
+ | |||
+ | < | ||
+ | |||
+ | Similarly, turning tangential cutting off is done by using the following code in the M6 macro: | ||
+ | |||
+ | < | ||
+ | |||
+ | This allows us to use the rotation axis when necessary by writing a '' | ||

+ | |||
+ | Since having a number of tools in the same program is typically necessary, we can turn tangential cutting (utilizing the rotation axis) only for the tools that require it, such as the Knife and Creasing Wheel (shown in the screenshot above). The other tools (camera, pen, spindle, etc) will have tangential cutting turned off by having their register #7005 contain a 0. | ||
+ | |||
+ | Using register #7005 therefore allows the operator to utilize a variety of tools with tangential control features. | ||

The DXF import procedure automatically generates the knife turn/knife lift G-codes which are inserted into the program, and which correspond with the settings listed in Config > Technology > Tangential Knife. This allows for easy set up provided the DXF file has been correctly modelled. | The DXF import procedure automatically generates the knife turn/knife lift G-codes which are inserted into the program, and which correspond with the settings listed in Config > Technology > Tangential Knife.
