Are there any manuals for Mach3 for a lathe out there other than the one on this site?  Something along the lines of " when we say X dro we mean the one on the left" for when there seem to be two X dro's on the screen at the same time.  I know, I know, I make a lot of beginners feel good.

Not that I am aware of.
There are some tutorials on some subjects in Member's Doc's.
One needs to read the Mach3  manual front start to finish and then "study" the manual for how to use.

What you want is really hard to provide since you could write a book on each different associated subject matter.
I know since I have attempted the task numerous times. Presentation is a challenge. Think i was up to 20 chapters
or so .......................
