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

RND and CHF, the blocks before

and after

RND or CHF must contain only coordinates in 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:
