if its of any use: the idea of Z being the tool axis is a bit predjudiced in Heidenhain CNC's you define the tool axis, and that ALSO defines the plane of circles. restated: the ToolAxis is an alternative to G17 G18 G19 but it infers the axis that is normal to the path plane, thats a bit different thinking than G17/18/19 in linuxcnc, perhaps using G17 G18 G19 to define the tool axis is an alternative way to say 'this is normal to my cut' for simple cartesian machines. And this 'toolAxis' idea might help resolve the safe way to jog away from stock. thanks TomP (tjtr33) ------------------------------------------------------------------------------ October Webinars: Code for Performance Free Intel webinars can help you accelerate application performance.
