Suppressing touch probe monitoring: M141
Standard behavior
When the stylus is deflected, the TNC outputs an error message as
soon as you attempt to move a machine axis.
Behavior with M141
The TNC moves the machine axes even if the touch probe is
deflected. This function is required if you wish to write your own
measuring cycle in connection with measuring cycle 3 in order to
retract the stylus by means of a positioning block after it has been
deflected.
Danger of collision!
If you use M141, make sure that you retract the
touch probe in the correct direction.
M141 functions only for movements with straight-
line blocks.
Effect
M141 is effective only in the block in which it is programmed.
M141 becomes effective at the start of block.
