You can only set the machine coordinates by doing a reference (homing) so no matter what you type into the Machine coords you can not change them. This is for good reason as machine coords are what Mach uses to keep track of things and normally a user will not look or care about machine coords,, note I said usually, there are times when you want machine coords but I will not complicate things at this time.
What the user looks at and uses is offset coords, for example, you home the Z axis so Mach knows where the zero position of the axis is in machine coords but you almost certainly dont want that as your Z axis zero position, you will want the end of the stock as zero. So what you do is move to where you want the zero to be and either hit the zero button for that axis or type into the DRO. You have now just set a Z work offset.
Afraid I do not like the Turn screen and I have never used it so I am not familiar with the naming convention of its buttons, but I am sure others will let you know exactly what they do.
