ER15 ultimaker 3 Extender

Recommended Posts

Posted · ER15 ultimaker 3 Extender

I have a printer ultimaker 3 Extender which has had problems especially in long impressions when it stops saying in the indicator ER15 which is something related to the temperature sensors of the print core as I understand, we try to change the print core as the page "https://ultimaker.com/en/resources/23149-heater-error-on-printcore" said but the error happened again, by checking the monitoring of the print I noticed that in a flash shot to 700 someone could help me with this thanks

It's probably a loose cable in the print head.  This is extremely easy to fix.  Remove the rear two screws - very long screws at the top rear of the print head.  After you pull those out the panel on top of the print head towards the rear half comes off.  Then push the cable connector down better and when you put the cover back on push the cable in a little for strain relief and also add some blue tape or other shim so the cable doesn't slide up again.
