Heat Sensor Busted but no error

[austincollias 0]

Hey everyone,

I recently received a used UM2 and it worked for a while but decided I wanted to clean it, I watched plenty of videos on how to take everything apart and was very careful, but classic too much hardened PLA made some pieces difficult to take off.

When I put it back together the head would not heat up. When i wiggled the sensor wire it heated up a little bit and then cooled down again. I could go into the settings and see the temperature hovering around 27-27 degrees c.

The only problem was there was no error message for a faulty sensor. Before I buy a new sensor I want to make sure other parts are not broken as well.

Have other people experienced this as well?

thanks!

It's the heater, not the sensor. If the sensor was broken it would be reporting 0C or 1000C or most likely something like "temp sensor error".

It's your heater that is intermittent. Are you sure the wires under the machine are okay? Probably they are fine if you didn't muck with that.

You are in USA so probably the cheapest place to get good heaters is at my store and I recommend you get a 35W heater as you can print more volume if you ever go with an Olsson block. http://gr5.org/store/
