Heater Plate not Heating

[Talmar 0]

For some reason, my heater plate isn't heating at all. Which is making it impossible to print anything. Nothing will stick properly. I've checked all the connections I can get to. I have an Ultimaker2. Any suggestions?

I'm assuming it is reading back the correct temperature. You can check this in advanced menu system.

If so then there is usually an open somewhere between the circuit board and the bed circuitry. It could be the wires fell out at the circuit board - especially if you put them in yourself - many people don't insert them all the way.

Or if you haven't messed with it yourself then it's more likely at the terminal block (the block with 4 screws) which is soldered onto the heater circuit board inside the heated bed. It's easy to get access to it - jsut remove the 3 leveling screws and the cable hold-down (2 more screws).

Usually you need to reflow (reheat) the solder on that connector - or sometimes one of the 4 screws (on the larger 2 wires) is a bit loose or one of those larger wires fell out of that connector. I mean every time the bed goes up and down there is a tiny bit of stress on those parts there.

ok, thanxs for the info. I'll break it down a bit later and see if that is the problem.

ok, all connections are secure on the plate. So this means there is probably a loose connection at the motherboard. Now I just need to find it and check it.

ok, after much unnecessary disassembling, I found out how to get to the motherboard... 2 screws under the build plate... wish I knew that before hand! Anyways, I checked everything, and nothing seemed to be loose. I put everything back together, did a factory reset, and started over from scratch. Build plate seems to be heating properly now, so I'll try printing something. Thanks for the help

Hmm. That's not good - will probably fail again if you didn't find anything. I still think it's my first guess - the solder is intermittent and needs to be reheated at the connector on the bed. There's 4 soldered connections. I would reheat all 4 of them and add just a little solder.

well, working perfectly now. If it goes out again, I'll take it apart and re-solder everything.
