My print head temperature seems to jump up and down 20C on my i3. It does not do it all of the time. It will jump around for 5 minutes and then the temperature readings will be steady. I have wiggled the wires to see if there is a short or loose connection and this does not trigger the temperature variations.
Any suggestions?

Re: Problems with temperatures
Is the printer M201 or other version?
You can try reloading the firmware, see if it will be better.
Download the firmware here:

Re: Problems with temperatures
I don't know which version, how can you tell. It is about 1 month old.
As I mentioned it does not do it all the time. It may do it for 5 minutes and then stop work fine for 2 hours. The temperature jumps up and down 10-20 degrees in a fraction of a second and then 5 minutes later it is fine. Do you think it is firmware or a bad thermistor? It is printing right now and the temp is consistent.
The board is the GT2560
Thanks

Re: Problems with temperatures
Generally speaking,it's the thermistor on the heating block caused it.
You can check if the extruder thermistor has a good contact with the heating block.

Re: Problems with temperatures
It was the thermistor hitting and then not hitting the heating block. Pulled the wires tighter in the up direction and the problem was solved. Thanks
