The difference between UCCNC and Mach3 is that UCCNC will follow the path exactly, unless you specify how far away it can deviate.
Mach3 just tries to maintain velocity, regardless of how far it may stray from the path.
Because of this, If your machine can accelerate fast enough, you can run at much higher speeds than Mach3, while actually having a higher level of precision.
What CAM are you using for this? If it was coded with G2/G3 moves it would be perfectly smooth.
To be honest I don't remember for sure what I used to create the gcode. I just was making a polishing wheel from mdf while in the garage and whipped it up and when I ran it was when I noticed how bad it was running. It may have been from inkscape or artcam probably artcam.
