EMC does not have a constant rate, either. The machine can not accelerate
from zero to whatever speed you are running at instantly. Every machine
has physical limits due to mass and limited power in the motion drive
system. Therefore, for the most versatile system, you need to do the
laser power adjustment.

Wow! Well, if he has the technology to do it, more power to him
(pun intended!)
