UM² - Difficulties to be extruded filament

Recommended Posts

Good evening,

In recent days, I encounter many difficulties to be extruded filament. The temperature of the hot-end skyrockets before maxtemp an error message.

I removed the head and I noticed that the plastic tip had suffered. He blackened and pieces fall into print!



What to do to repair the hot head?

I tried contacted the Ultimaker team. However I need a serial number. Ors, I bought my printer in Ultimaker and I can not find my purchase data on the site!

It's rude here!

Thank you

Good evening,

As shown, I ordered at MakerShop.

To my way they fail to make the financial transaction. It is not possible to provide me the white part on my Ultimaker2.

What other provider in Europe or abroad to enable get this part became unavailable on the site Ultimaker?

thank you,
