YES, that's right,
Thank you very much! It made the circle perfect now !
That was far from obvious for me, to find that hidden adjustment in the ocean of settings.

Thank you for giving me good advices.
When I start Mach3 the values in Offsets (Alt-5)  menu are all 0 , but after moving the machine to where I want to have it as start point and in the Program Run (Alt-1) menu pushing the zero x end y button , it is impossible to get 0 in all the Offsets (Alt-5) menu. This probably meant to be so but running the g-code program from the cut circle wizard makes the circle totally wrong seize, are these problems connected?

In the Tool Path , the window  Program Limits    Absolute Coordinates , it looks like the picture from Tweakie but the values are all 0 before I load the wizard and after I loaded it the x range is -84.000  +28.000 and y range  is -56.000   +56.000  and I can not alter the values even if  I hit the ENTER key after entering new values.
 I tested in MDI mode setting x and y and z to zero and wrote   g-code in the INPUT line : G02 X0 Y0 I-27.9 J0 F100   and that made a nice circle of right dimension.  
Is something wrong in the Tool Path and I how can I correct it?

Thank you for help, but I don't manage to change it, it jumps back if I try to put in a new value.
 I tried to get around the problem by using a 8mm tool to get 60mm hole instead of 56mm , but now the awful machine make a hole of 120mm , and the program limits are now x -84 ,  + 28  and  y -56 ,  +56. Why do they jump around and make the hole anything but right?

I'm new to this, but tried to use the wizard for cut circle.
 When I try diameter 30 I get 56, on the display while cutting the numbers for X goes from  -12,8 to +38,  and for Y from -25,7 to +25,7.
This is quite frustrating, do anyone have an idea what I'm doing wrong?
