The screw looks like it may be 1mm pitch instead of 24tpi.....if it IS 6mm dia.
.04166666666666666666 (1 / 24) is pretty close to 1mm.

Ah and RC could also be correct, if that was the case it would be 1600 steps per mm
LOL

I suppose your'e right.  I had to try it. Unfortunately I coudn't start the spindle (noise). It appears to be more accurate ie it moves 25mm at G0X2.

Arrhh I didn't see those last few posts. I was going to say that I had to add an extra 0 (200) to the wizards input to get a 20mm circle. Has that anything to do with your typo.

Yes my typo had it set 10 times too small, had the decimal point wrong LOL
 I am a bit confused however, a G0X2 should move 2mm not 25mm.
Do you definitely have your units set to mm? Look under the Config menu then at Select Native Units and see what it is, should be mm if you are going to use mm as your default. Also as RC said are you sure its a 24TPI screw as it would seem more logical for it to be metric if the OD is indeed 6mm.

When I entered your first number 151. and  I would get a 2mm move with G0x2 and the decimal point was one out in the wizard inputs to get the correct cut ie 200 to get 20mm cut.

The leadscrew is 6mm so I have entered 1600 in the steps per. Now I get an accurate result in the wizard and the G0X2 moves 2mm still.

Does all appear to be correct now. 8)

I made a few test cuts today and all appear to be working fine. Dimensions are more accurate with steps per,  set at 1511 rater than 1600.  :)
