The G52 work coordinate system zero point offset can be canceled by
programming a G52 block with zero values for the axes to be cancelled.
The following block would cancel the work coordinate system offset for
the X axis only.
G52 X0;
A G52 offset can also be canceled by executing a G92 or G92.1,
performing a control reset or an E-STOP reset operation, or executing an
end of program M30 or M02. A G92 command only cancels a G52 offset
if one is active when the G92 block is executed. A G52 offset may be
activated at some time after the G92 block is executed even if a G92 offset
is still in effect.
CAUTION: G52 offsets are global. This means that changing
from one coordinate system to another does not cancel the
offset. Do not specify a change in coordinate systems
(G54-G59) unless the effects of the offset have been considered.
