I've never seen anything like this before. It gets about half way into the program and at the same exact point in the program, the Z plunges about a 1/2". The Z DRO DOES NOT reflect this. Last time it did it, I hit the estop. The Z was clearly at about -.5000 but the Z DRO said -0.008 which corresponds to the program. Here is the code.
N7450 G0 Z0.3750
N7460 G0 X1.2493 Y0.1734
N7470 G1 Z-0.0128 F20.0 --------Problem occurs right about here.
N7480 G1 Z-0.0099 F50.0
I'm not sure why it's making a Z plunge move followed by a Z feed rate move. F20 is the plunge feed attached to the tool. F50 is the feed rate. Either way, I don't see anything that would cause a Z plunge. I ran this program 4 times and it did the same thing at the same exact point in the program every time.

N7510 G1 X1.3482 Y0.2162 Z-0.0526
N7520 G1 X1.3582 Y0.2202 Z-0.0566
Has anyone seen anything like this? This is a new setup and it's been a while since I set up a router. I'm not used to dealing with 3D tool paths.
Thanks.
