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
