Hi, I’ve been making a wood box but I’ve discovered an issue. I designed the box with symmetric measures, but when after finish the job, you can observe a little difference between X edges and Y. I measured all edges, and I’ve compared with the design, and the problem is in “Profile Outside” job (You can see pictures). I try to run some calibration patterns and all of them show me that the machine is OK, the motors, ball bearings, belts, electronics etc. I run the same design but using “engrave and a pen” (see pictures and measures) like a bit to see the plot, but these plot is perfect according with the design. I’ve thought that maybe it can be a CAM software error. What do you think?

Have you calibrated for effective end mill diameter /runout? Shapeoko CNC Router, Rigid, Accurate, Reliable, and Affordable
