Topic: Thermistor Resistance reading

I've been getting the dreaded "Printer stopped due to errors. Fix the error and use M999..." So I figure it must be a thermistor problem. I unplugged the thermistor and tried to get a multi-meter reading at 200ohms but I couldn't' get a reading no matter what pins i touched. Even though that's the case it seems to read temperature fine when I start to heat up my extruder end. What's the deal?

The printer is usually running great for about an hour and then it goes into that error.

Re: Thermistor Resistance reading

Bad connection somewhere in the thermistor wiring.

With the thermistor at room temperature, you should be using something more like 200k as a setting on your meter.

D'oh, stupid me. I think I missed that little "k" In the troubleshoot I was reading. Any recommendations on how to find where the bad wire is? Or should I just buy a new thermistor?
