You'd better be in G91 (incremental) mode!

You're right about the mechanical ease of doing this. I can't speak
for others, but I was 'against' the idea because I was thinking of a
big, strong spindle motor and the $$$ electronics to run it...

And more so because, at least for the original problem, there
were/are other simpler (IMO) solutions...
