pattern doesn't carve

[Sliverfoot]

I am trying to carve these pieces of a picture frame. Loading the board and the bits seem to go as they should but when the carving is supposed to be happening nothing is being carved.
The bit is turning , the board is moving , the truck is going up and down, but it is not carving into the wood.
When designing this I changed the default bit for all the carves from 90 degree to 60 degree but I can't see how that should cause the problem. I measured the thickness of my board and verified that it is 3/4. The clear silicone collar is pushed down on the bit as far as it will go. I'm stumped.

Did you watch the bit actually touch the bit plate on far side and then come down and actually touch the wood?

[Sliverfoot]

I saw it lower to each spot. I'd have to run it again and watch with a light to see if it touches or falls just short.
The one thing was different with this project is after choosing it from my project list. the machine "verified" and some numbers scrolled quickly up to 333.

Just tried it again, The 1/8 cut bit touches the bit plate and the wood. The 60 degree touches the bit plate and doesn't even try to touch the wood before carving. It goes from the touch plate back across the wood to where it starts to carve (or tries to).

I do not think that is it Al. The V bit touches the bit plate. What else would cause the air cut?

Maybe the sleeve or the collar on the bit shaft needs to be longer or slid up. I don't know what the tolerances are but it might be possible for the bit to touch the bit plate and still be too short.

Missed the touches...

I feel ridiculous asking this as it is pretty basic and I'm sure that I'm off base but here goes ... is the "conform" box checked in project designer?

Have you used the V bits on this machine before? If I recall there were some C machines with a controller bug. A wrong parameter and the centerline air carved.

I have used both bits on my C machine without any problems so it should work.
