Sorry should have been more specific. Thanks for the help

Pictures are worth a thousand words.

Generic Circle- I designed a circular pocket about 5" in diameter and about 7/16" deep to be done in 3 passes. As the CNC would make the helical plunge cut to start the pocket it would be a perfect circle, once the helical plunge cut reached the final depth and it started to work out the final diameter the circle was almost a perfect multi faceted circle. see pic above.

I read that I may need to adjust the Constant Velocity setting from the stock setting, does this sound accurate?

G43-I see...I should never need G43 because when I do a tool change I would have to reset Z to the new tool height manually, am I understanding that correctly? How do I have fusion stop generating the G43 code or should I just manually delete it every time? I looked at the Post Processing file and that is way over my head to manipulate, I am definitely not a coder.

My Setup:

UCCNC version 1.0249 with Gerry's 2017 Screenset from thecncwoodworker.com

UC100

3 axis router 4'x6' bed with y being the 6' section

I have no offsets set

I have it set to the standard xyz configuration, nothing reversed, machine home is the front left of the machine as I am looking at it from the front.

If I remember correctly I have my stepperdriver set to 1/4 microsteps (800 microsteps per revolution)

My z axis is a screw drive at about 5000 steps per inch and xy are belt drive at about 500 steps/inch velocity

As far as Gcode I am mildly familiar with it, I have to keep a reference sheet handy, I looked up all the M and G codes after I had the problem but I could not figure it out which is why I posted the question.

Here is more of the code, It is several hundred lines long but here is much more of it.
