I've had this happen on two occasions now. Carve a beautiful 3d image rough and finish (VCarve Pro V9) the first time and the next the rough cut is too deep. Time wasted - 4 hours. Any suggestions as to the cause?

Re: Rough cut too deep
If you hit your upper limits on the z axis you will lose your z zero. It thinks it's still moving but in reality it's not, but the computer thinks it is. therefor if you think it's at say 1.5 but the machine thinks it's at 2 and the next time you use it, it's not where you think it is. You must rezero your z axis. I hope I explained it.

Re: Rough cut too deep
Not sure I understand. For the second piece, I set the bit on the starting point and zero all 3 axis's and run the program. I can tell immediately that it's going to deep. Looking for oil?
Re: Rough cut too deep
Is the z axis zero set on top of material or bottom of material?

I have two questions:
Did you use the same thickness material for each carving?
What is the clearance (Z1) and Home/start Z gap set at?
The answers to these two questions could support what Tony is saying.

Re: Rough cut too deep
Another part of the puzzle is: how deep is too deep? Is the difference between the two carvings on the order of tenths of an inch? Or is it larger, like 2 inches?
One thing to remember if we're talking about a v-bit carving with a 60- or 90-degree bit, variations in height produce very pronounced changes in line width. So if, say, one board was mounted warp "up" and the other warp "down", and there was say a 0.050" height difference (not uncommon in large, unplaned wood panels), then a cut that was 0.025" deep would change dramatically if that shape isn't either accounted for, or removed. I wonder if that might be part of the problem?

Thom
