Was doing a pid after changing hotend to volcano and now it seems like my sd card is corrupt. It will disconnect and give me a javascript error and disconnect. was working fine. so I'm sure I changed something the problem is I'm not that familiar with this firmware to know if I caused this.
here is my M122

it did overheat while pid tuning twice it faild and got super hot. but still worked. then I ran a print and heard a pop and then printer haulted due to heater fault. now I have it tore apart. gonna order new heater. you could be right that the thermistor came loose. not sure what caused it but it was expensive mistake

ok will do thanks. not sure what happened but my keenovoo heater smoked and cracked my 5mm bed. not sure why this happened. but I'm ordering a new heater and gonna use .250" aluminum tooling plate for the bed. little more than glass but at least it wont break.

5mm glass

I did a pid on my 110v ac 800w heater for my bed. It worked one time. Now when I try a Pid for the bed I get this now "Auto tune cancelled because temperature is not falling"Ive lowered the temp from 90 to 60 with same result. thanks for any help

It was not having m501 in my config. Works perfectly now. Thanks!!
