Trying to figure out the best way to align a rotary axis along the X axis.
I seem to be getting a spiral effect. I cut a 2" wooden dowel 8" long. I used a Starrett combination square to scribe a line, verified with a Woodpeckers precision square… The ends are 90 deg. I put the dowel in the rotary and align the beam to the line on one end, then tell it to move 200mm. I re-align the other end. I repeat this process until its aligned with the X axis.
When I burn a line the circumference of the dowel, the ends don’t meet. The length of the line is right but the start point and end point is off to the left.
Something is off but I’m not sure what. Maybe the dowel is walking, but why?
Today, I tried burning text on a powder coated tumbler. The text was clearly not straight along the circumference.
