Howdy. I've been using Cut 3D for a few years to make art, I use cnc to get me 90% there then do the rest by hand adding details and mods as I go. Over the weekend I was making some pieces much smaller than I normally do and realized that the actual part made by cnc was consistently about .1" smaller in the x axis than what I had drawn. The y and z dimensions were also a bit smaller, but only by a few hundredths, which is acceptable.
These 3D cut parts are supposed to match up with some 2D cut pieces which came out as drawn. I checked some older pieces I had made and they appeared to also be off about .1" on the x axis. But these are much bigger pieces and they don't have to fit anything so I never noticed.
I draw in Rhino 5 and export as a stl. I don't think it's my machine because 2D cuts are spot on. Have I inadvertently changed a setting in Cut3D, or never set it up correctly? Is this just the way it is and I need to stretch all my drawings by .1" x axis before I export?
Any help appreciated.
