Hey Sharkcutup!

Thanks for taking the time to run that.

Question: Just so I am sure, did you run virtual zero or just set zero and run the cutter paths?

I am using a Shark HD3.

If you ran Virtual Zero then there is definitely a glitch with my machine. I have opened a ticket with Nextwave to see if I need a software update. I know they take their time with answering the tickets so I will wait and see what they say.

In the meantime, I have done a few things since:

1. I programmed just the outer circle and offset it to run at the bottom of the V carve. Set it up with virtual zero and got the exact same results with no "Z" compensation.

2. I reprogrammed the cutter path by grouping the text and circles in V-Carve; same result, no "Z" compensation

3. I divided the circle into two quadrants; one quadrant for the word INDEPENDENT and one quadrant for the rest of the words.

a. independent compensated like it should with good results

b. the large quadrant with RECOVERING WOMEN RIDERS did not compensate

4. I then divided the circle and text into 3 quadrants; 1-INDEPENDENT, 2-RECOVERING, 3-WOMEN RIDERS and all compensated like they should

Note: Each quadrant had to overlap each other to clear out the pocket. There are dwell marks at each of the overlaps but, all in all, the results were decent.

So I have come to the conclusion that any perfect arc over 180' does not compensate for the "Z" when using virtual zero on my machine.

Now, you have perked my interest in the post processor. I am using (and have always used) "CNCShark-USB 3D Contour (inch) (*.tap). I set it at this and it worked and I have never changed it in 3 years.

I am wondering if this would make a difference so I will go and program a couple of circles and see if the "Z" compensates.

Will let you know the results soon.

Thanks!
