I don't have any experience knurling titanium, but if this is your first time knurling you're in for a fun adventure.
Base starting reccomendations for feeds and speeds are around 100sfm with .005-.01 feed for bump knurling.
Quite honestly there are no givens when it comes to knurling I've found, you have to pick a starting point and work from there with what you have. I could be running an identical set up as you, but my knurl pin is slightly more worn and allows the knurl to spin more freely resulting in different speeds and feeds.
Basically though your main concern first and foremost is that the knurl going down to a proper depth and tracking correctly, once you have that baseline then you can tweak things to perfect the knurl.
Best advice I can give is to pick a speed, find your desired depth and play with your feed. Sometimes you really need to jack the feed so the knurl bites and tracks, but the higher the feed the more deflection you'll have so you'll find yourself offsetting the knurl lower. Also most people will use a dwell allowing one to two full revolutions at depth, depending how long the dwell is you may find yourself offseting up again..
There are a lot of variables to play with, try to pick a speed and work from there with your depth, feed and dwell time. Modify one at a time to see your results. You may slow down the feed and decrease your dwell and find the knurl looks the same as it did with a faster feed and longer dwell..
Let's just say I've torn hairs out trying to get knurls right in the past. The form-roll catalogue has some base starting points and calculations you can do to get your starting values, from there its up to you to figure it out and make it work. I've spent hours before getting a knurl dialed perfect, only to set the same job up a few months later and not have the knurl work at all ending in having to re-figure the whole dang thing out again.
Best of luck to you and hopefully you'll figure it out in a nice timely manner
