ED,
Plate is nicely done.
Maybe the guy should have a matching tatoo or is that only bikers.

Kevin,
Was there any difference in the part zero location between the two programs?
Just a quess!

rirhett,
Don't know a whole lot about PP cards.
The purchased card should be Windows Certified Compliant.  ( not just some verbage that say's it works with .....). Make sure that you have an agreemant with the purchaser to return the card if it doen't work or otherwise pass on it. Some cards are single or dual voltage ie; 3.5v or 5v out from the port. Need to solve your pp problem. Sorry I can't be of more help.

Sorry I mentioned the "adjusting steps " since if I get into this kind of discussion folks will think it is good practice not realizing that something was done for a very specific understood reason and it's not normal to do so.
 
You calculate and use the steps per unit and check / reafirm as noted in the manual and NEVER change them.

There are books about maching techniques and suggest you review that information.
BTW, a few swipes with a piece of sand paper can go a long way in adjusting something to dimension.

Dave,
Understand what your saying. Here's what is nice. You can go in a pick a particular section of a turned piece along the
Z axis staying outside or inside the undercut, make moves to a point, thus your not restricted. Now exactly how to do that stuff and the exact sequence along with tool definition is a different story. You need to get all the buttons and logic "Synergy" way of doing it down. I hacked away and was sucessfull, then douldn't duplicate what i did
( who takes notes when their hacking away), even posted code. How buggy it is, well who knows ( and they are all buggy!) and there is no forum to ask questions.

Dave,
I downloaded the file and it self extracted / installed the program. Never had to reboot or anything.
Don't know,maybe just lucky on my end.

Daniel,
What you have is what you need to work with and do the best you can with it.
Comparing diffrent machines is useless.
No code changes are done.

Hey Dave,
As you get down in the tolerances  the whole system comes into play. If It's big variations then maybe there is  one culprit to be found causing a problem. But  when you start cutting hairs sometimes it's difficult to refine the machine
 / system and frankly may be wasting your time.
Here is an example:
My old mill, which I CNC'd, will produce an egged hole when milling a circle to hold a bearing. The gain in the lead screw is 0.00025" / inch and that gain varies over a 12", but there a few sweet spots in it's travel, the ball screw is within spec. I can use the sweet spot, even adjust the steps, and do an extra step or two and produce a very close tolerenced hole which is not egg shaped if i want to take the time to do so.

My engraving machine is different in that the X & Y have phenomenal accuracy and the Z movement is great also.
So no need to even think about tweaks, but, the tool runout can become limiting. 
So there's were i come from in my response and logical to me ( FWTW ).
