Just got my new rotary in today and think I have the steps per rotation dialed in. 1" square is exactly 1". Object diameter is input, as well as the roller diameter, caliper measured. I did a scan interval test and I’m not getting a clear engraving- lots of choppy lines and it’s not precise- the inside is rounded, deepest at the middle, and not at all smooth. I can’t think of any more information to add here that will help diagnose, but happy to answer any questions to get some help! As shown in the photo, the 4 circle test was done at 150mm/sec, 30 power. Scan intervals are noted under the circles.
