Hi All;
I have been trying to fine tune settings on an SKR 1.3 running on a Wanhao I3. Recent version of Marlin (2.0.7.2). All was going well enough until I was printing a couple of layer print to test bed adhesion and Octoprint disconnected with Bed Temp error. From then on I could never connect again. Unless I turned the machine on and connected very quickly where I would get a message from the printer saying it loaded the EEPROM and then Octoprint would lose connection. I surmised that Marlin was crashing. Several days of hair pulling ensued until I came across this on Marlin Git Hub:
https://github.com/MarlinFirmware/Marlin/issues/14470
Reading this it looks like the EEPROM can get garbled especially around bed temperature. So I imagined if I set the bed and nozzle to thermistor 998 (or 999) it might help and it did. I can connect. I reset the factory defaults in hopes to clear this issue. But it does not. So my question is how do I get around this issue so that my printer is not a fire trap?
As a side note my thermistors worked as type '11' which is 25 Degrees C @ 100k. My ambient is around 22 and it is just above this. And if I warn the hotplate with my hand the resistance decreases. This to me is enough to say the thermistor is working.
