All good. I think the autogenerated config for ratos needs to add this for the sht42

@TheTik so following back up on this… the new hotend had the same issue so it was not hotend related. I checked mellows documentation of klipper for the sht42 that I am using and it looks like they have a 2200 ohm pull-up resistor for the thermistor and the generated ratos configuration leaves the default klipper pull-up resistor set to 4700 ohm

Temperature does move in the right direction when heating it up but I dont have a thermistor to compare agains to generate a comparison for error at this time

The only other thing I can think of is that the thermistor had been spliced with another set of wires and the connection might not be great

I am rebuilding someone else's project so I have no history on this hotend. i'm trying to figure out whether this has a junk thermistor.
