That’s a high-priority task on the todo list. Resuming a program requires some internal changes that run pretty deep so it’s not a quick thing to add but it’ll get added as soon as we work out the difficult parts.
If you are working on this, I wanna add another suggestion:
Let the user input a range from percentage and to percentage, so that an arbitrary sub-range of the whole gcode can be executed. Also, display for each toolpath in Carbide Create which percentage range it covers in the final gcode. So that the user can identify where to restart a certain part of the job.
