I have been wanting to put up more on the V4 wizards, but I have been working on them a lot and have not had time to make screen shots to post.
We have moved them to a strong Job orientation. A job will have certain properties- like Units (mm or in), material, and a couple choices of things like the Z strategy. A NewJob operation always brings up a Tool Select operation, which stays in effect until you select a new tool.
The main screen has a list box showing the job elements, and a right click on the list will let you edit the element, delete it, or move it up or down in the list. This is much greater job control than the Mach3 version.
The main screen also has a large toolpath display, with full interaction to rotate, pan, zoom, etc.
You will be able to save a Job Template and re-open it, make an edit to one or more ops, then re-post the code.
It is really a lot more capable than the V3 product, and it will be offered for Linux, and Mac as well as PC. I am pretty excited about it, and every time I think I can make a release copy Brian comes up with some neat new idea that sends me back to the keyboard.
