Help With OD Grooving

First time trying grooving with Fusion on lathe.    Can anyone make this look this better?  File attached.

While I am a seasoned machinist, most of my experience is focused on milling. However, I've been around enough lathe guys to know a few things. One of those things is that not a lot of grooving holders are capable of withstanding a heavy side load. Oh sure, you can take a finish pass with one, but any rough pass really should be done in a plunge manner. So, I changed the toolpaths a bit and gave you two Groove paths. The first roughs out in a plunge manner (with a spring cleanup pass) and then the second enters from either side of the groove and heads to middle (actually shoots over) to finish it. Take a look at the attached file. 

I am curious if there would be a way to lump this all into one toolpath, and what settings would get you there. I'll play with it a bit as time allows...

thank you @seth.madore.   I went ahead and used my original toolpath early this morning and it worked, but I appreciate your input here.  On your first rough groove.....I have a beginner question.   How are you getting it to plunge?  It looks to me it's in the roughing pass.  If I uncheck your rouging passes tab generate the plunging is gone, but I am unable to get it to plunge again with checking the roughing passes tab the second time.   So how do you get the grooving into plunge mode?

Honestly, I poked around with it just trying a few different settings until I found what worked. I did peek at a couple of the Turning Samples in Fusion as to how they accomplished similar functions.

You can select both operations (your and mine if they are in the same file) and Right Click > Compare and edit. This will give you a new box you likely haven't seen. At the bottom left, you can set the filter to "Different" and see all the different fields
