G14 disables scaling on all axes. When scaling is disabled, the center of
scaling and any scaling magnification factors are cleared. The next time
scaling is enabled, these values must be reset. In addition to G14, M99 in
the main program, M02, M30, and a control reset operation disables
scaling. The system powers-up with scaling disabled.
Your system installer specifies in AMP, on an axis by axis basis, whether
scaling is allowed. See the literature provided by your system installer for
additional information.
