Go to General Config and enable enhanced pulsing and see if that helps.

i did that and it seems to cut correctly now (just ran a few lines and it looks right)

but i hit my emergency stop in the middle.. like i did before... went to MDI... typed in my X0,Y0 it's now a lot closer... but still not my original start point.

When you hit E-Stop or for that matter press Stop when axis are in motion you will almost certainly lose position. You need to rehome your machine after doing one of thesee. The proper procedure, if its not an emergency is to press feedhold and wait for motion to halt before pressing the Stop button.

if i let the part run through, is now correct (kind of, my bit may have slipped in collet. dia are correct but z is off)

at end of program it stops at x3,y.234. now when i mdi x0,y0 it goes to original start 0,0 like it should. but only if i let program run all the way through.

checking that box, what did it do... and why did it change if it worked before?

Enhanced pulsing attempts to make the pulses cleaner, if the pulses are not clean then  the steppers/servos will not follow  the code correctly as steps are missed. The default setting is to have that enabled and 99.9% of people should have it enabled.
