The code as sent supposedly increments twice where it should be once. However when checked after the "Do" it is zero. BTW the User Manual index says "Break" is discussed on page 158 but I cannot see it!

You have to scroll down a tad to see the break part of the loop. For sure you have an infinite loop going on when I commented out the break line...
Ok, your assigning the value of Height_Machined_away to Z_cutting_height so your outer loop will always remain true.
Take a look at my lathe facing subroutine for some hints on how to step down in depth.

I see why the o301 while loop never ends, your looking for an equal condition when one can never happen with 1.0 as the cut depth and 3.5 as the depth to cut.
Sorry it took so long but I only have a couple of minutes between parts on the mill. (yea I'm working today)

Thanks a lot for your help John. The actual fault was that I was testing a negative value against a positive value. Silly I recognized the problem on the Z code but forgot it on the Y part of the code. Software is now running as it should with a tweak to ensure that I never climb mill whilst facing the top. Your help with the use of "Debug" and "Break" made all of the difference. Whilst the faults were a pain it was a useful excersise in programming Gcode. for the mill, I learnt a lot.
Thanks again

Glad you got it sorted out.
Now you can take a tested subroutine and add it to ngcgui with a slight change to the variables. This will allow you to fill in the blanks for each subroutine and concatenate them into a complete program.
