Need thermistor specs, cocoon create.

Hi All.Does anyone know the specs for the thermistor in the early Cocoon Create.Tried a couple from eBay and still getting fault. Temp display jump to Def/215.Problem started with printer loosing power halfway through longish print (sometimes). thermistor read open circuit and can't see any info on the thing, maybe my eyes?No printer for 3 weeks now, getting withdrawal's.Any pointers appreciated. Roy.

hey. have you been able to fix the problem?
just installed a new extruder and im now having the same def/215 problem.

Read an article that "The Wanhao Duplicator i3 Mini & rebrands like the Cocoon Create"

https://github.com/andrivet/ADVi3pp
ADVi3++ is a fork of the Marlin Firmware for the Wanhao Duplicator i3 Plus (and its clones: Monoprice Maker Select Plus, Cocoon Create, ...).
It includes both Marlin itself and screens for the LCD Panel.

and suggest using "1 : 100k thermistor - best choice for EPCOS 100k (4.7k pullup)"

This is untested by myself FYI did a search on the WWW and came up with this read the article,

Remember before flashing new firmware to your 3D Printer make sure you have a backup of your present firmware.
