I just got my Snapmaker 2.0 and have printed some items with success. But I have noticed the while the build plate is warm to the touch. It is nowhere near the 50 degrees that the Touchpad says it is. I tested with a basic thermometer and got about 25 degrees. Shouldn’t the build plate be very hot to the touch ?
It does say it is reaching the right temperature.
Check the thermistor wires that measure the hot-end. There are descriptions in this forum on how to add thermal paste to ensure that the temperature is measured correctly.
@ITmaze I’m assuming you are addressing the hot end, and not the bed they are referring to.
@mavsol22 It’s possible the thermistor on the bed is bad. No chance you have a multimeter that can read ohms? If so the 2 middle wires in the plug should be about 100KOhm.
The bed takes awhile to heat up. I’d say if you’ve given it a long time, like 15 or 20 minutes, and it’s still not at temp, you’re going to need to email support to get them to replace it. Could be a loose connection at the controller or something simple, also.
is this the case at room temperature and hotter or colder will be more or less resistance?
trying to understand how it works exactly, i think that makes sense though.
This resistor is an NTC 100K with a beta of 3950. Plug those values into this calculator https://www.thinksrs.com/downloads/programs/therm%20calc/ntccalibrator/ntccalculator.html
And you’ll get a graph of something like this
The nominal rating of a thermistor is at 25 Celsius, so roughly room temperature
