Error

Hey guys, after I updated firmware for my ultimaker 2connect it started to throw out an error about build plate heating. Tried a official sites help but id didnt work

Which error was it exactly?  The errors all come with a web page you can jump to on the ultimaker website.  So look at the error more carefully next time and follow the advice (go to that web page and read everything carefully).

@gr5 its error 203. I looked but there are only told about checking build plate wires. but we did that and nothing changed

Ah.  https://support.ultimaker.com/hc/en-us/articles/360015627259

 

Yeah - that's the temp sensor.  The thinner 2 wires in the photos.  So this is never caused by a bad sensor.  They are made of platinum and will probably still be working thousands of years from now.  It's always in the wiring/connectors.  Usually at the print bed because it moves up and down.

 

Do you or a friend have an ohm meter and know how to use it?  You want to remove the two smaller sensor wires under the printer and attach an ohm meter there (if the wires are connected to the printer that can throw off the reading.

 

The bed should be around 109 ohms when at room temperature.  You can look up a PT100 temperature table to see what temp is what resistance.  all PT100 sensors use the same table.  All of them! Unlike other types of thermistors.

 

So the white cables at the bed go into a connector.  I would take the bed completely apart (remove the 3 leveling screws and pay careful attention to how it all goes back together.  Then remove and reseat the wiring at the print bed.  Power up the machine with everything taken apart and check the temp of the bed.  then wiggle the bed around a bit, changing the angle of the wires and see if the temperature suddenly jumps away from room temp (around 20C).

 

Anyway a common failure is the solder that connects the connector onto the build plate.  Or the wires just need to be removed and reinserted.  (at both ends of the cable).

Hey I went through all the wires as written in Official site but its still crushes and throws out that Error. Can anybody tell or suggest what to do next or how to solve that problem? because it throws that after around 1,5 hours when printing
