[Upgrade your Ultimaker 2 with the Extrusion upgrade]

it is increasingly difficult to find particular type filaments to brick or marble or concrete or any other type of color that is different from the standard ones to the size of 2.85mm because Ultimaker continues to insist with the filaments from 2.85mm?

Why did not alter the upgrate to UM2 + this too?

In all the shops we do not find anything but filament 1,75mm all manufacturers design printers filaments from 1,75mm.

Have any of you found an interesting solution to this problem of filament diameter.

We are 600 hours of printing almost all made with PLA. In fact, the main problem it is to under extrusion. According to you may depend on the coupler?

Hi, do you think this coupler must be replaced?

Ciao, quindi in questo modo è possibile cambiare l'ugello da 0.25 e poi rimettere quello da 0.4 in pochi secondi?

Basta svitarlo e riavvitare il sostituto in funzione di quello che si deve stampare?

Hello, I would like to print a very small object, but did not succeed.

I wonder if you can do it with the Ultimaker2 hotend 0.4?
