I am trying to achieve a seamless pattern engrave 360° around a cylinder. I dumped my roller style rotary for a chuck style with a 5:1 gearing. I have verified my steps per degree in grbl as I can etch a horizontal line, rotate 360, 720, 1440, or whatever and still hit that same mark exactly again and again.
So in the rotary setup I specify an object diameter and it provides a circumference. I create a graphic with that same exact vertical dimension but no matter what it seems that the pattern comes short and I have a gap. Am I missing something?
