machining a part and generated a post from Fusion 360.

imported the TAP file into PathPilot and it shows a massive "plunge" on Z axis?

Or am i imagining things? the GCode doesnt reference Z beyond like -0.3 inches

loaded gcode into GWizard Editor and the simulation there doesnt have this at all? neither does Fusion's CAM

So i took a chance and I ran the cycle with near zero speeds and it never plunged or followed that line down on Z?

is this normal?

Can you post the G Code?

[kdupreez]

Sure.. here you go

Looking at the GCode it goes to Z0.193 at f15 then to Z0.0324 at F15. It then plunges to Z-.023 at F5 which all looks normal.

Not sure why it is displaying this way. I will load it on my mill tomorrow and see what it looks like.

When I load your program in my Mill this what I get in Side View Mode I did not have the tools the same as you but it looks like it runs ok.

You might try setting your workpiece z 0 first before loading the program to see what it looks like.

ah, yeah, great point, let me go zero off the workpiece before loading program and try again.

I ran the program in air, the thing I noticed is the rapid down to the work height was very slow on the initial rapid, after that they seemed OK, I had a couple arc too small warnings, the program did run though, really couldnt tell much as I was cutting air.
