Most is correct, as for the M601 command it is to set another zero position for the far left end of the mandrel. The M602 is the same, but for the far right end of the mandrel.

The command G4 L602 C40 is actually to locate the 40 degree angle relative to that of the M602 save point.

I tried the program earlier with an above normal priority and I saw no change. These delays occur in the L602 returns. All of the L601 returns are spot on.

I can bypass the L602 and L601 by simply only using a G4 C360 command to just allow for rotation and not rely on the L602 or L601 to tell the carriage to move. This of course requires some math formulas that I know nothing of.
