We got a CR-10 S4 and are trying to replace the built-in manufacturer firmware which crashed all the time (if you tried to move an axis more than 10mm at a time it would hang requiring a power cycle). Firmware is up and rudimentary prints are working-ish. We are having trouble with layer adhesion on the filament it came with, and printing whatsoever with a purple Inland PLA. Upon the advice to increase the temperature (all the way to the max of 260!) we are suspecting thermal issues.
From what we can tell, this should use TEMP_SENSOR_0 1 (this is from sourcing "stock" replacement parts and seeing other advice from other "CR-10S" recommendations). We have not specifically confirmed the thermistor as we do not immediately have access to an ohmmeter. We haven't messed with any other thermal settings. I strapped a meat thermometer onto our hot-end, and while I expected some thermal loss from being outside the heat-block, I'm concerned with what looks like a scaling issue. Here's the settings as reported by the LCD, then the temperatures read from the meat thermometer:
190 124.2
195 127.9
200 130.6
205 133.5
210 136.7
215 140.3
220 142.2
225 146.4
230 148.7
235 151.1
240 153.8
245 156.6
250 159.3
255 163.1
260 166.8
While the setting is to increase the temperature by 5 degrees, it appears to be increasing on average by 3 degrees. Assuming that's ballpark 9/5, I was worried about C/F conversions but the numbers don't really make sense.
Lastly, when idle/no heating, the bed and extruder both register at ~25C in my office, which seems correct.
We've consulted with several references (like this, although we're using a newer marlin: [
github.com] ) but are getting nowhere. Any advice is appreciated!

Edit: We have been able to flash the manufacturer's firmware to the printer. While we're not happy with the crashing, but a benchy has successfully printed at 230C which we believe eliminates hardware as a cause.
