How to just cut a single straight line

Postby KGunnett » Thu Jul 26, 2012 3:00 am

I'm pretty new to V-carve, I don't even have a CNC machine yet. I figured that it was better to learn something about the software before ruining a bunch of wood. I'm learning by watching the videos...

I just haven't figure out how to do this. I draw a square box. Inside that box, I place a large box, on top of that I place a smaller box, and another on that, sort of forming a set of stairs. I join or group the boxes together, then I remove all the interior lines. I then select the large square and stairs, and use the pocket toolpath to leave me a raised platform in the center of the work. Lets say that is machine down to a 1/2 inch.

Now, this is my probem, I would like to put back some of the lines I deleted, but only deep enough to make them show up (.005?). I select the line I want to engrave, and V-carve tells me it is a open vector.

How do you do it, all I want to do is engrave a straight line, and tell the program to center the bit on that line. I'm sure it is something simple.

And on the subject of open vector, is there a way to get V-carve to show me where they are located?

Thank you in advance...

To find the open vectors look on the Edit menu and you'll find an entry called "Select All Open Vectors".

For the toolpath you need to use a Profile toolpath rather than a VCarve toolpath. As you've found out a VCarve toolpath will only work on closed vectors.

You will also find that in v-carving a single line, your selection of a shallow depth will show up as a line of varying width if the top of your material is out of parallel with the horizontal plane of the spindle. In other words, a selection of 5 thousandths for a depth may not show uniformly on your workpiece.

Oh just great! I just did what you said, and now feel like a complete idiot! :) The profile toolpath was the only place I didn't look.

Thanks again....
