Hi
Both axis are out by the same amount
Y axis
Moving the Y axis in and out 20 mm 2 times there is an error of 0.01
4 times an error of 0.02mm
6 times 0.03mm
8 Times 0.04mm
10 times 0.05mm
And the same for the X
I have tested the lathe dials by cutting a some metal manually and measuring it with a micrometer and its perfect from this I can deduce there is nothing wrong with the mechanics of the lathe.
If i repeat the above with a g code program the error is the same
