Background
Pathpilot is able to use parameterized and expression based programming in place of or with common G code commands. Two recommended resources on use of macro programming in Pathpilot are: the LinuxCNC documentation on G code syntax (http://linuxcnc.org/documents/ ) and the operator’s manual for your machine. Tormach makes every effort to maintain compatibility with LinuxCNC operation and the significant majority of our changes only add new functionality, however compatibility cannot be guaranteed and is at the sole discretion of Tormach.
This article is intended to detail a number of the additions to macro programming that Tormach has made from that of LinuxCNC.
Parameters
Tormach has created new named parameters that can be used in G code programs, their name and functions are listed here.
