Hi Roy,
I too am using John S software running in DOSBox.

Not sure which version I am using as I downloaded all four, some seem to work better than others.

I have not used the lathe for a while as I have busy with another project.

When I first tried the lathe the offsets were all wrong for the toolpost/tools I was trying.
I had a good read of the section in the manual and reset the offsets using the instructions in the manual.

I seem to remember that the tool did not go to the start position I was expecting.

If I remember correctly the offsets are set by manually driving the tool to the work piece in manual mode and then saving the position and this becomes the offset for that tool.

I wasn't the easiest thing to work out from the manual but it did work.

Best of luck.

Keith.

PS I assume you downloaded the manual with the software.
