I cut a lot of small shapes out of thin aluminum sheet and while I’ve been getting much better at milling aluminum, I still often end up with a rough edge around the top of my pieces. I usually just sand the edges smooth afterwards but I’ve been thinking it might save me a little time and effort to just run a chamfer pass with the 501 pcb engraver. I run chamfers passes with wood projects quite often by making an small outside offset then run a no offset tool path with a vbit. I assume I can take the same approach here but I’m just not sure of the offset I should set and what to set the DOC to. I’m not looking to have a noticeable chamfered edge per se, just enough to smooth out the edges. Any advice on a starting point would be greatly appreciate!
Offset geometry, or draw offset lines (I’ll do this using drawn geometry at corners for guides so that it can be cut off at a consistent diagonal), then assign a No offset contour toolpath to the appropriate depth — draw the stock and tool in profile and use the upper portion of it.
