Post Process issue for Openbuilds grbl

Post by DBrownley »

I posted recently about several issues I was having integrating Sheetcam with Openbuilds Black box controller. I have managed to work through most of the problems; However, I'm not sure how to resolve this one.
These are the tool paths in Sheetcam before post process:

These are the tool paths in openbuilds interface after post process:

As you can see, tool paths are climbing up the Z plane. Any help would be greatly appreciated!

Are you using touch-off probing? The preview has no way of knowing the probe trip point so it assumes that the probe has tripped at the furthest end of the specified probe distancel. This will result in the display you see. It should cut correctly.
