G-Code, CAD, and CAM discussions / Arcs not cutting smoothly

« on: February 14, 2012, 08:58:59 PM »

I profiled a part this morning that should be relatively simple, but the arcs are coming out as what seem to be either line segments or much smaller arcs. I don't see anything in the g-code that should cause this, so I'm pretty confident it's not a Cam issue (I'm using CamBam). Any ideas what might be causing this and how I could correct it? Thanks!
