[Is Ultimaker II good quality? / Heated bed error]

I seem to have fixed mine, fingers crossed. After investigating pretty much everything, I re-soldered the solder joints on the heated plate - both at either end of the sensor and all 4 along the connector strip. Soldering iron set to 470degC, as it feels like high temp solder.

All the joints looked OK visually, but re-wetting them seemed to fix the problem - for now anyway.

I detached the wires to do this and of course re-attached into the terminal block, so it may have been a fault with a screw terminal I guess, but I'd checked that before without success.

 

[Is Ultimaker II good quality? / Heated bed error]

I repaired the solder on my bed easily with only a soldering iron (a very good one) and it has worked for many months with no problems since then. It's really quite easy to fix. If you ask for help on this forum you will get it.

People have similar problems with all the other companies out there (like Makerbot) but those other companies (like Makerbot) will not let you post something like this on their forum ever. So you won't hear about those problems so much but I hear about them all the time at shows.

 

I have the same problem with heated bed sensor reading too high, so stopping the machine. Can you supply a bit more info on how to fix this with a soldering iron gr5?

I guess it's high temperature solder on the heated bed connections. Do we just remove the heater plate and re-heat the solder for all connections - plus I guess the temp sensor component?

Is it a standard thermistor by the way - if anyone knows the part number it would be relatively easy to swap out the thermistor...

thanks
