Trouble creating tool path on embossed sketch

[mattlaudato]

I was happy to figure out how to create a tool path and carve 'deep letters' from a text sketch that was embossed onto a model. The problem is, I can't recreate it, and at this point I'm stuck. Approach is:

- Create a rectangle sketch

- Extrude it to match my exact stock size (for example, 246x30x12mm)

- Create a text sketch on the upper face plane

- Emboss the text -2mm. Looks great, ready to manufacture

- Go to Manufacture, create a setup with stock exact size of model (no add'l stock). I'm using generic 3-axis CNC w grbl post for my FoxAlien Masuter Pro - has worked fine on prior projects

- Now the fun begins. I had prior success using a 3D pocket clear to cut out the letters, with a SpeTool 0.5mm ballnose bit - the results were fantastic. So I select this tool, set the parameters. No problem.

- At this point, I'm stuck. No matter what geometry I select, I get either no toolpath or a trivial tool path that bores a hole or two in some of the letters, but doesn't follow the emboss contours. Frustrating thing is I have an earlier project from yesterday where this worked. I'm at wits end figuring out what is different between the two projects and could use some help

Files attached below - the TEST pocket Engrave works, the Breadboard emboss is the broken frustrating one.

Thanks in advance for any suggestions.

Your model is attached.  I did not understand why you selected the top of the stock as your 2D Pocket path instead of the actual pockets created by the letters.  Also, you has Stock to Leave selected which did not allow it to clear the material in the letter.

I did not address the machine warning since I have not idea as to your machine configuration.

I'll take a look. I thought I had a 3D pocket, but maybe it was 2D in the version I attached. The problem was, I couldn't select the pockets in any obvious way. Selecting the edges on the face and/or the edges at the bottom didn't work. How did you select the pocket? The tool warning is innocuous in this case; I have enough Z clearance to properly zero the bit and cut.

With a 2D Pocket, I select the multiple edges at the base of the embossed letters.  Most letters have two edges except the “F” as it does not have any islands.

Your video is very helpful, thanks.
