<p>PID autotuning is quick and easy, and relates to the most potentially dangerous components of your 3D printer: the heaters. It makes sense to do it as a first step. This procedure is covered in this video: <a href="https://youtu.be/qCtL0Yd_w0I" target="_blank">Two easy fixes for 3D printer temperature swings</a></p>

<p>It may be preferable to have the printer as close to printing conditions as possible during these tuning procedures. That means having filament loaded and the part cooling fan on for PLA temperatures. If there is no UI button available to turn on the part cooling fan, you can do it manually via gcode with <b>M106 S255</b>.</p>

<p>For the X, Y, and Z axes, the steps per mm is usually consistent between printers and rarely changes with modifications. As long as belts are tight and true, it rarely needs to be tuned.</p>
<p>For the extruder however, variations in extruder hardware and filament means it is worth properly calibrating the extruder steps per mm, or E-steps.</p>

<p>Setting the stepper driver current is an important step in calibrating a 3D printer, although typically the value does not need to be exact. There is a window within which the printer will operate without issue.</p>

<h4>Hot end temperature</h4>
<p>Typically, filament comes with a recommended hot end temperature. It is recommended to use values either side of this. For instance, if a PLA filament asked for 200 degrees, you may vary the temperature from 190, 195, 200, 205, 210 (the default values of the form). Typically, the first layer temperature will be elevated to increase adhesion with the bed, especially if a lower than usual temperature is being trialled for segment A.</p>

<p>We set a feedrate or movement speed in our slicer, but the printer does not instantly reach these speeds. Like a motor vehicle, it needs time to accelerate. If the distance of the movement is short, it may not even have time to reach the specified speed. This can determined with the handy <a href="https://blog.prusaprinters.org/calculator/" target="_blank">acceleration calculator</a>, available on the Prusa website.</p>
<p>Complementary to acceleration we have jerk, replaced by junction deviation in newer versions of Marlin. These settings have differences, but both are essentially responsible for making sure the printer does not come to a complete stop between each movement, but rather decelerates an appropriate amount depending on the angle of the next 'corner'.</p>

<p>Junction deviation requires a single value, whereas jerk has separate values for X and Y. You can leave them the same or enter independent values.</p>
<p>You should only change either acceleration or jerk/junction deviation for each test print, otherwise it will be impossible to know which parameter is responsible for any changes.</p>
