- [Female Instructor] In this movie, we'll continue testing for incorrect calibrations of your 3D printer, and talk about how to mitigate those problems as much as possible. We'll keep using the test print we introduced in the last movie. - [Male Instructor] This part has features in both the x and y directions that should measure: 10 millimeters, 25 millimeters, and 50 millimeters, as well as an internal measurement that should be 10 millimeters. If all of these measurements on one axis are too large or too small by the same percentage, you have a scaling error. Scaling errors can be caused by an incorrect value of the firmware parameter steps-per-millimeter. This parameter tells the printer how far it needs to turn each motor to move the corresponding axis a given distance. These numbers should be calculated based on how the linear axes are built, as described in the link shown here, among other places. If you're an…
