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.
Effect
M141 is effective only in the block in which it is programmed.
M141 becomes effective at the start of block.
Danger of collision!
When dynamic collision monitoring (DCM) is active, the 
TNC might move the tool only until it detects a collision 
and, from there, complete the NC program without any 
error message. This can result in tool paths different from 
those programmed!
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.
