UM² - Difficulties to be extruded filament

Recommended Posts

Posted (edited) · UM² - Difficulties to be extruded filament

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

You can buy a hot end pack that has a temp sensor and PTFE coupler, nozzle and others. If you don't have one the I would suggest getting a olsson block or even the new UM2 upgrade kit.

Cool, thank you for this information.

Olson will be compatible with my old UM²?

It's worth then not?

I have not seen too many examples of this upgrade (complete disassembly, assembly) and test!

I think we just ordered anything Ultimaker now, it must go through resellers :(

Yes it is compatible with all UM2's and works very well, it's now included in the new + printers.

There is and installation guide Here

Yes you have to use resellers now sadly.

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,

You can order one from 3dsolex Or one of the re-sellers found on This page.

It is called the TFT coupler and is very good.
