Also, on QIDI X-MAX, since there's an enclosure, as well as lowering the bed temperature, maybe try to leave the door open for some filament (such as PLA).

<p>As you can see, no stringing! But the base of each tower is deformed, non-circular, and extremely weak. The tops of the towers are perfectly circular, so I don't believe it is entirely an X, Y axis issue.</p>
<p>This is PLA at ~195 °C with a 64 °C bed on a QIDI X-MAX.

Also tried different temperatures, Z-adjust, and re-leveled multiple times. Any thoughts on the cause of this?</p>

This is an odd issue I haven't seen before, but your bed temperature is quite high for PLA and the nozzle temperature is quite low. These could be factors.

The warping on the base's corners suggests too much heat on the bed.
