How to avoid CNC crashes Answered
I am wondering if it is possible to define particular areas on the bed of my CNC machine which I do not want the toolhead to pass over.
My setup is an Arduino powered CNC pen plotter running GRBL. I am generating GCode in inkscape.
I know I can set a safe height for the tool to pass over work safely but what if that height doesn't suffice. Can I define an area that the tool must not pass through?
As a simple example:
Before running a file the tool is at the origin. On sending the file the tool will take the most direct path to the first line to cut/draw. Imagine there is an obstacle that would cause a collision if the tool takes this direct path. Can I do something to ensure the tool navigates around that obstacle?
I hope that makes some sort of sense :)
Any ideas appreciated
