<p>I just updated my Maker Select Plus from the stock (I believe RepRap-based) firmware to Advi3pp, which is Marlin based. The printer starts up and everything seems okay, but I haven't actually tried a print yet and there was a message during the upgrade about deleting incompatible settings. </p>

<p>What do I need to do to recalibrate the printer following the firmware upgrade?</p>

If it fails here you may need to adjust settings. When it's done, measure it and see where you are. You might not need to do anything else.</p>\n"}]
