If you print another job afterwards these higher values will still be in place. If you are unsure how to restore your previous values, the easiest thing to do is to power cycle the printer.</p>

<p>It's also worth noting that the <b>M201 value acts as a per axis limit for acceleration</b>. For example, if you set the <b>M204</b> print acceleration to 1000 but the X and Y <b>M201</b> acceleration limits are only 800, then the <b>M204 P</b> value will be capped at 800. Use <b>M503</b> to see the current <b>M201</b> values, and if necessary, use <b>M201</b> to set higher X and Y acceleration limit values to suit.</p>
<p>We can store the new value(s) to EEPROM by sending:</p>

<p>You would then repeat the test with all of the acceleration values locked at your preferred value for each segment, but this time varying jerk/junction deviation.</p>
