Profile cut on a line beyond edge of workpiece?

MillMage Software Questions

I’m attempting to use a routing tool to bevel along a path which in places follows the exact edge of a pre-cut, 6.75mm thickness acrylic workpiece. Because the path is not closed I must use a profile with ‘along the line’ selected. I must also (I think) offset the line position beyond the outside edge of the workpiece by a distance equivalent to the minimum cutting radius of the tool, and accomplish the cut in a single pass, with the depth set such that the z coordinate of the minimum radius of the cut is at at height -3.335 mm (i.e. half the thickness of the workpiece. ) I also need to lead into the cut from the outside, which puts me further outside the edge of the workpiece. I can actually specify this in the software, but it won’t allow me to preview it or generate gcode. Is there an alternative way to do this which I can use?

Look in the main settings - there should be a toggle to “discard out of bounds shapes” or similar. If you disable that, it should let those through.

Thanks Oz – That worked – it did exactly what I was asking for.

… of course, what I actually needed was something different :expressionless: Its no good to follow the same line with a fixed distance offset.I need to follow it with a tool offset --i.e. the equivalent of a profile with tool offset to the ‘outside’, except in this case, there is no outside because the shape is open. so i need to specify the offset direction in some other way… e.g. ‘toward the outside of the workpiece?’

To illustrate; say I have a rectangular object 100x200x10mm, and i want to round off the bottom left corner by cutting a circular arc centered at (40,40, -10), with the tool edge offset toward the outside of the object (i.e toward the closest edge (or away from it in a negative direction if you’re actually on it)

… or is that one for the ‘Pro’ version? (!)

We don’t have an offset function for open shapes yet, but it’s planned.

When done, it would offset to the right or left of the line, determined by looking from the starting point of the line in the direction that it leaves that point.
