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 RND and CHF, the blocs before
and after RND or CHF must only contain coordinates on the
working plane
If you want to approach the contour on a tangential path, you
must use the function APPR LCT. The block with APPR LCT
must contain only coordinates of the working plane
If you want to depart the contour on a tangential path, use the
function DEP LCT. The block with DEP LCT must contain only
coordinates of the working plane
Before using the functions listed below, you have to cancel
M120 and the radius compensation:
