<p>I bought an Ender 3 V2 printer and printed successfully with PLA and PLA+. Ender 3 V2 is rated at &lt;= 250 °C but when I set temperature above 200 °C to print to PLA+, I get an error message &quot;Nozzle is too lowperature&quot; and the printer freezes (the term lowperature is actual and not a typo error).</p>
<p>I tried to raise the temperature gradually. I started at 200 °C and have gone to 205 °C and a little bit more. I started printing and I might get this message again or might not. Also, the temperature seems to change or lower while printing. It is not stable.</p>
<p>Any suggestions as to what causes this unstable behavior?</p>
<hr />
<p>Following the above behavior, I was able to raise the temperature to 213 °C and I was printing for 10 minutes or so, then I got the message &quot;thermal runaway&quot;.</p>
<hr />
<p>I managed to capture the event <a href="https://youtu.be/oo0f237iTVo" rel="nofollow noreferrer">here</a></p>
