Hi,

I wrote a little program to make a z-axis go up and down for a test.  It looks like this:

O001
M98 P17 L900
M30

O17
G1 Z.38 F50
Z0
M99

The problem is I can only go to about 950 times before getting a "too many nests" error.
I'd like to go 5,000 up-down cycles before stopping.  Any ideas out there?

Thanks,
Mike
