Original X-Carve 1000m - Issues EVERYTIME I try to use it

Curve fitting helps a great deal, especially if you’re using UGS. The motion planner on the XCarve hardware is basically an Arduino, so it’s amazing that it works as well as it does, but it has limits. The Arduino used by GRBL doesn’t have much memory, so it can’t look very far ahead while trying plan the motion. If you create paths with lots of very small line segments, the planner isn’t able to look far enough ahead to create a good motion plan, and gets stuck being really conservative

You can use the $12 parameter to tune the arc (G2,G3) performance in grbl. Larger numbers give fewer line segments at the cost of not matching the curve exactly. The default value results in a tight fit to the curve using many line segments.
