I am in the process of making a bunch of name plaques to hang under a US flag. When I go to carve them the bit barely touches the wood. Using VCarve Pro and the board is flat and touch off is board surface. It makes enough of a mark to be seen, but not enough to ship to a customer. When I put in a 3/64 start depth it works fine. Ideas to why I need a start depth?

Post a link to your crv file. Also, is you board REALLY FLAT? One way to make sure is to surface the board, leave it in place, then reset Z to the top of the newly surfaced board. Before you plane, take a pencil and scribble all over the board. After you plane, all the pencil marks should be gone. If not, then the board isn't flat.

After setting the Z-0 location using the puck...lower the bit back down until it just contacts the material and look at what this is showing for the Z-axis on the coordinate screen.
(Repeat in multiple locations).
Most often the boards are not perfectly flat, or the MDF spoil boards are needing to be surfaced.
If all the locations are reading more than just a little different then this will let you know that something is not flat.
Beyond that the touch off puck thickness may need to be adjusted as well.

They were run through a commercial planer from 4/4 down to 13/16 and then through my drum sander to 5/8. I will try the pencil trick, but if they're not flat from the planing and sanding I don't know what will make them any flatter.
Stay tuned...

1. Flatten your spoil surface.
2. If that doesn't fix it, flatten the workpiece using a fly cutter - then the top of your material will EXACTLY match the plane of your cutter.
3. Break the file into individual letters and poke them down in 0.01" increments until I have uniform depth across the board.
MANY signs later, that philosophy, in that order, works every time.

Problem solved, guys in shop were not setting tool depth between each piece. Of course they waited till they scarred up 4 pieces to tells me! My fault for not training them better...
Thanks everyone for your help!
