General Mach Discussion / X-Z cutting clips top of material

« on: October 08, 2020, 02:38:55 PM »

I posted this problem under another topic, maybe I didn't explain it very well.

On 3D parallel roughing with single line X-Z or Y-Z  movements I always get the top of the material clipped. I turned off Constant Velocity and still get the clipping. There has to be something I have setup wrong. With every other operation the router is working flawlessly and has from the beginning.

Has anyone else experienced this?

General Mach Discussion / Strange Z Axis problem only with MeshCAM generated G code

« on: September 14, 2020, 08:26:53 PM »

I'm finding that 3D roughing code generated by MeshCAM clips the edge of the stock as if the Z axis starts moving too soon. It only occurs in 3D roughing. Mach3 has been working flawlessly for the past 3 months doing 2D and 2 1/2D routing. This is the first time I've used 3D. The errors seem to occur when a single line contains a X and Z move. I've tried turning off Constant Velocity, but is has not changed anything. I've tried slowing down the Z axis, which makes it worse (bigger bite on the edge of the stock) I've tried slowing down the X and Y axis, no joy. I'm hoping that someone else has already solved this before.
