I just started using cut2d, and when I cut holes (inside radius for the tool path) they are always smaller than specified. For example, I have a hole which is .07" wide, and a tool (physical) width of .0375. If I use that tool width in cut2d, my hole ends up .065 instead of .07.
So... I have to enter a tool diameter of .0275. When I do this, my hole comes out at .07".
Question is why did I have to tell it my tool is .01" smaller, to get the correct size hole?? It doesn't even make sense, because since the offset happens on both sides of the hole changing the tool diameter by .01" should also change the hole diameter by .01", but it doesn't, it changes it by .005!!
It seems like it is not correctly compensating for tool width, or it is trying to add an additional offset.
This has been driving me crazy all night, lots of wasted material before I figured out what was going on.
I am using EMC, but there is no EMC post processor, so I have been using G-Code Arcs (inches).
Any ideas? I'm stumped. No compensation is enabled in EMC either, I see G40 as the only compensation related g-code active (which is compensation disabled)
Thanks!
