<p>How would one go about squaring the gantry relative to the frame?</p>
<p>Referring to the image below, distance A and distance B are not equal.</p>
<p>Also would this account for the reason why when I attempt to print a circle it is not perfectly circular, and when I try to print a square, it is tilted?</p>

The yellow is 12\xa0V and the black is GND. If your bed were rated at 24\xa0V then its resistance would be higher than that of the 12\xa0V bed. The best solution for you would be to get a 12\xa0V heated bed, as opposed to using a boost converter. Reason being is that you would need to get a boost converter that can tolerate over 200\xa0W of power! It's just cheaper to replace the bed.</p>\n<p>Finally, you need to consider the heat bed, the extruders and the steper motor's power needs before you purchase a PSU. If you had a multimeter with a current measurement, then you could accurately determine how much power each one uses and then purchase to size.\nBased on your bed size (600\xa0mm) I think that 500\xa0W should be enough.</p>\n"}]
