<p>After a long battle with SKR Mini v2, TFT35 and BLTouch and creating the right firmware. I thought I was through it all and ready to start printing again after finally being able to set the Z offset and auto level the bed. My printer has other thoughts. Now my bed temperature will only heat up to 10 °C below the set point temperature and after a few minutes it starts beeping and says this on the screen &quot;<code>Heating Failed: Bed Printer Halted, Please Reset</code>&quot;. As an example, set it to 60 °C, it will get up to 50 °C normally and stop at 50 °C.</p>
<p>Anyone gone through this? I'm sure there is some setting in the firmware that I have missed up. I'm hoping someone can educate me on my mistake.</p>

My bed was set to 60\xa0°C and it wouldn't heat above 52\xa0°C without giving the &quot;Heating Failed: Bed Printer Halted, Please Reset&quot;. After PID tuning (which I did after the fan firmware change too) the bed heats up to 60\xa0°C and stays there now.</li>\n</ul>\n"}]
