Hi,
I have an Ultimaker 3 Extended.
Of late, I've been getting the error "Max Temp. Error on Build Plate. Go to Ultimaker.Com/er14". This prevents prints from going forward.
Document ER14 suggests that the problem might be connection between the build plate and the wires in the back. I've pushed and worked them a bit to ensure that they are seated properly, and this has not cleared up the error, although access to these wires is tricky given their location and the fact that the tray cannot be brought up when the error is present. (Indeed, the only thing one can do is cycle the power on the printer.)
Another Ultimaker forum suggested the issue might be contact between the print core and the print head, which seemed to make sense given that I had recently changed one of my print cores. I took the core out, cleaned the contacts with a Q-Tip and Alcohol, and replaced it, ensuring that it was seated properly.
This, too, did not work.
Before getting service on the printer, is there anything else that I can try on my own? The printer cannot be used at this point.
