I believe the 10T uses a 1-line cycle.

set chamfering amount in parameter 6212 (0.1L ~ 12.7L), or
set chamfering angle in parameter 6213 (1 ~ 89 deg)
set finishing amount in parameter 6219 (0 ~ 3.2767 inches)
set number of spark-out passes in parameter 6220 (0 ~ 255)

Our older Mori works with the example Mr. Coupar provided. K requires a decimal.
