Re: thermal runaway - jumping temperatures - pid - ...

I have the same problem too. I have tried auto tuning the PID settings, reuploading the firmware, checked the connections and swearing at it. None of the things made a difference.

At the moment I have to preheat the nozzle to 3 degrees above printing temperature, let it "stabilize" there, and then ...

Which type of lead screw

I can't seem to find any specifications on the lead screws used on the a30. I have just bought one, and it has been a fight to get it running smoothly.

Re: Prusa i3 a pro. Ribbon cable melting

Thank You so much for your fast reply.
I have already messured the resistance in the heatbed to 1.1 ohm but forgot to mention it in my first post. Sorry about that :oops:
