Common Error Messages
G code out of range
A G code greater than G99 was used, the scope of G codes in LinuxCNC is 0 – 99. Not every number between 0 and 99 is a valid G code.
Unknown g code used
A G code was used that is not part of the LinuxCNC G code language.
i,j,k word with no Gx to use it
i, j and k words must be used on the same line as the G code.
Cannot use axis values without a g code that uses them
Axis values can not be used on a line without either a modal G code in effect or a G code on the same line.
File ended with no percent sign or program end
Every G code file must end in a M2 or M30 or be wrapped with the percent sign %.
