another meshcam question

Hi Gerry,

No I am using a 4 axis part. When I try to set the zero Meshcam says that it can't for a part like this.

I'll check it out tonight.

Sorry, forgot about ya.

I loaded the ring into MeshCAM, and rotated it 90° around the Z-axis. Then set the stock to the default size, go to "Set Max Depth" and click middle in the stock section. You're right, I get the same "can't set zero" error when using 4 axis mode. That's because the Z=0 must be the center of rotation. You might also want to check the box that says "machine geometry only" in the toolpath screen.

But, once I set Max Depth to center, I didn't have any problems. I set up Mach3 for 4 axis and it appeared worked perfectly. (don't have a machine to actualy try it.)

I also found what appears to be a bug and will submit it to Robert. MeshCAM doesn't write a G1 A0 line of code at the start. I'll also request a rotation feedrate and the ability to use rapid rotations.
