No mcode shown on dry run?

[Fred_evans]

Hello you chaps-

I typed in the code (as shown page 3.10 of the manual) for a dry run   

I put line numbers and remarks in (to only do one word at a time)
to help understand and debug

two questions- first one just to understand the logic

when i cycle (single step) the highlighted line on
the screen is the next line to be executerd - while the line
under the toolpath display is the line previous line already executed.

Am I correct in assuming the the highlighted line will be the next line
to be run and the displayed line under the toolpath is the line just
executed?

second question
the last line "m 30" doesnt appear on the screen ?

is this all correct or am i missing something?

many thanks
fred evans

HIYA Fred, Put an  % in after the M30.   Mach requires an empty line after the last word in the file. The % is used a lot to make it visible.

Just a thought, (;-) TP

Or just hit "Enter" after the last line you type. Mach3 needs a carriage return to see the last line.
