I think you hit the nail on the head! I changed the resolution to 200 and got a lot closer consitantly. when my new motors and lead screws come in i suspect it will get much better!

120 - 122 depending on axis. i am using some old ibm nema 23 motors with delrin ball screws that are pretty aggresive 1.75 inch per turn

Let me clarify. I do not have an external DRO on the machine I am talking about the computer screen readout in Mach 3. Hope this makes more sense.

my components are not accurate by any means but i do not understand why if i tell the axis to move one inch the dro doesnt read one inch. I dont have encoders so im not sure why the difference?

I input as follows
go
x -1.000
y -1.000
z -1.000

And the Dro reads
x -0.9984
y -0.9970
z -0.9997
is there some way to correct for this?
