<p>Lower acceleration and jerk will result in a slower print time, as the printer reaches top speed more gradually and corners at a lower velocity. This is easier on the printer, with potentially increased component lifespan and less need for regular maintenance. It reduces surface artefacts such as ringing/ghosting, unless it is far too conservative, in which case it may introduce bulging in corners.</p>

<h2>Calculating maximum feedrate - optional but strongly recommended</h2>

<p>This is simplified test that will not be as accurate as using the gcode generator on the <a href="calibration.html#speed" target="_blank">Speed/Max flow tab</a>.

<p>One strategy is to calculate the fastest your 3D printer can move while extruding cleanly, set this feedrate in the slicer, and then tune acceleration to meet this speed. If you are not interested in printing as fast as possible, skip to the next section.</p>

<h2>Acceleration Tuning</h2>
|

<p>We will now produce an acceleration tower to conveniently test back to back settings in a single print. If you would like to slice the model yourself, here is the STL: <a href="files/accelerationtower.stl">accelerationtower.stl</a>. It should be sliced with a normal base, but hollow, no top layers and only 2 perimeters.</p>

<p>The only thing you need to know before this test is whether your firmware is set up for jerk (older) or junction deviation (newer). Entering <b>M503</b> via terminal will give a list of printer variables:</p>
