To calibrate the extruder, we’ll be sending 100 mm of filament through the hot end. Use your calipers and mark the filament 120 mm before the entrance to the extruder. With most RAMPS and Atmega-based printers, you should also be able to use the Serial Monitor in the Arduino IDE.Įnable Relative Mode on the extruder by sending the command M83 to the printer. You’ll need to find the section of your slicer dedicated to tethered printing,Į.g. In Simplify 3D, you need to go to the machine control panel window. Then connect a slicer software that allows you to send a single-line g-code command to the printer.Į.g. Simplify 3D, Pronterface, Repetier Host, and OctoPrint. Link your printer to the computer, with USB or WiFi if your printer is able. Load your filament like usual, taking care to remove any old material. When the printer is correctly preheated and ready. If the non-flexible filament is loaded, Nice job! Heat that up and we can get moving In order to calibrate your extruder, you’re going to need to preheat your 3D printer’s nozzle to the temperature meant for your filament. A computer with slicer software installedġ.Yet this 6 step guide is easy enough that you’ll feel like a tech pro by the end- Let’s hop to it! To calibrate your extruder, you’ll need the following: Luckily we are here to help! Calibrating your extruder can sound a little intimidating, perhaps even a job best left to professionals. In extreme cases, over-extrusion can also contribute to clogs or jams in the hot end- which can be a costly mistake. On the flip side, too much filament and your project will have unsightly blobs, strings, or drooping details. Leaving a sad mess where your project once stood. Too little filament and gaps will appear between layers, or the layers themselves will be weak just missing completely. Adhesion will suffer, and prints can be subject to layers warping or delaminating. However if your calibration is off… things can go wrong. This is how your 3D machine is able to create any shape, figure, or design with such ease. 3D printing relies on extruder calibration to create the computer generated design by pushing a precise amount of filament through the printers hot tip.
