Effect
M120 must be located in an NC block that also contains radius
compensation G41 or G42. M120 is then effective from this block until
radius compensation is canceled with G40
M120 LA0 is programmed, or
M120 is programmed without LA, or
another program is called with %
the working plane is tilted with Cycle G80 or the PLANE function
M120 becomes effective at the start of block.
Restrictions
After an external or internal stop, you can only re-enter the contour
with the function RESTORE POS. AT N. Before you start the block
scan, you must cancel M120, otherwise the TNC will output an error
message.
When using the path functions G25 and G24, the blocks before and
after G25 or G24 must contain only coordinates in the working plane.
Before using the functions listed below, you have to cancel M120
and the radius compensation:
Cycle G60 Tolerance
Cycle G80 Working plane
PLANE function
M114
M128
