My Calibration Process

thingiverse

This is the process I use to fine-tune each filament. Part of the process I studied a while back and for the life of me cannot recall the site to give credit, if I do I will add it immediately. I begin by printing the 20x20x5mm cube with the following settings in Simplify3d. Extruder tab Extrusion Multiplier - 1.00 Extrusion width - manual - 0.48mm (assuming a 0.40mm nozzle) Layer Tab Primary layer height - 0.20mm Top solid layers - off Bottom solid layers - off Outline/Perimeter shells - 2 Infill - 0 I print the output STL and measure the width of the perimeter shells. My goal is to achieve 0.96mm, so if it's under 0.96mm I go back to Simplify3d and adjust the Extrusion Multiplier until I get as close as possible to 0.96mm. Once the Extrusion Multiplier is set, I move on to the 3-hole test STL. I created this STL to test holes for a few things I use frequently, including three different sizes: 6.5mm, 3.2mm, and 2.7mm. The 6.5mm hole fits SMA perfectly, while the 3.2mm hole accommodates an M3 screw passing through it. Meanwhile, the 2.7mm hole allows me to thread an M3 screw into place. On the Other tab in Simplify3d, I use Horizontal size compensation to adjust the holes to the correct size. Positive numbers make the holes smaller, while negative numbers make them larger.
