PLC Includes for X1366P

The PLC Includes files allow to systematize and share values and functions among the Hardware and Software PLC procedures within your profile. The below list includes information for the default version of the myCNC X1366P Plasma Cutting profile. The information may differ between profiles, as well as different versions of profiles, and should be used as a general reference only.

A list of G-codes within myCNC software is provided here for reference: G-Codes list

File - pins.h

Defines hardware inputs and outputs (refered to via names, such as OUTPUT_MARKER, INPUT_ARC, etc).

NOTE: The pins.h file is present both in the Hardware and Software PLC tabs within your Settings. On Linux systems, the pins.h labels create a link to a single file - when the values are changed in either the Software or the Hardware tab, they also automatically change in the other upon program reload. This implementation does not work under Windows, therefore the programmer must monitor the synchronization on their own and update the values in both files in order for the changes to take effect correctly.

File - func_plasma.h

Contains plasma cuttings functions (typically related to THC, THC triggers, etc)
