UM3 ER18 after update

Recommended Posts

Posted (edited) · UM3 ER18 after update

Hi

 

First time i tryed printing after updateing the firmware it auto leveled and started printing fine but because the print failed (lost grip on build plate) i abort it. It then lowered the build plate and unloaded my filament.

I then reloaded the filament and tryed agian. It started printing, failed agian and when i aborted the print the bed didnt lower and i got the ER18.

My UM3 now shows the ER18 (print head connection error) every time i turn on the printer or sometimes it will start up but then gives me the ER18 message agian when i try to auto level.

 

I have tryed resetting it to factory settings but that didnt change the firmware back as i had hoped and it still says ER18

 

Could this be because of the firmware update or is it just a coincident?

I think it's a coincidence as this behavior has not been reported with the update.

 

So the cable comes loose quite easily.  It takes all of 1 minute to fix it. 

1) Remove the 2 long screws at the rear of the print head.  You access them at the top.  Removing those completely will not do much at all - things will still stay together. 

2) Then remove the rear top cover - it covers the rear half of the print head and holds the cable in place.

3) Seat the cable better.  Push down on both ends of the connector with some kind of tool or small finger.

4) Put some blue tape or scotch tape or other shim around the cable for better cable relief so the cable won't slide upwards and pull the connector out again a few months from now.

5) Put it back together

Tomorrow you will find that you can fix this faster than you can locate and have the first sip of beer and you will wonder what all the sorrows were for, lol!
