This script will append the time remaining to every line in your file. It can also append the time remaining until the next op begins.

It will tell you time remaining per line per toolpath _OR_ the total cumulative time remaining. At time2.cgi I have a version that will tell you both on one line.

So, if you have two Ops (Roughing) and (Finishing), you can put (Finishing) into Toolpath 2 and it will tell you the time remaining until (Finishing) starts and the time remaining until the end of the program (after (Finishing) starts).

If you only have one op, or if you just want to know how long until the program is done, enter the last line of your file in the Last Line of File box.

The toolpath lines can also obviously be tool change lines. If your CAM outputs something like M6 T66 H66 G43 enter that instead of (Roughing), etc.
