ignores heater temp limit #12

Open gabecamp opened 3 months ago

gabecamp commented 3 months ago

seems to ignore the heater temp limit and goes to 100c ,built as normal except for using 2 Adafruit SHT31 as in and out sensors,

SasaKaranovic commented 3 months ago

@gabecamp Is the heater sensor reporting that temperature or you manually measured it? Can you share which components you used and which PCB vendor?

gabecamp commented 3 months ago

Using all the parts from the BOM on GitHub except for 2 sht31 sensors , the PCBs were using the Gerber's from github with jlcpcb. The temps are from the ds18b20 as per the schematic. After some testing I found it does hold temp correctly after turning it off and letting it cool a few times. Could it possibly be the pid loop causing thermal runaway? It does seem to be stable now after a few times turning it off and letting it cool down ,and then restarting.

It's good that it's stable now. I had mine running for couple of years now and had no issues. If you find way to reproduce this, please let me know.
