Anyone tried the Adafruit 1.75 filament hack for UM2+?

Posted · Anyone tried the Adafruit 1.75 filament hack for UM2+?

I watched this video

And I want to give it a try but can't find any source online of someone trying this with success. So naturally I am dubious. The other times I search about p[eople using 1.75 filament on the ultimaker I get information of doing hardware modifications to the bowden and coupler. Has anyone tried this with success? I don't want to do it all the time, I have a few ocassions where there is a filament I really want to try but the manufacturer does not make 2.85 diameter (in this case, a beautiful burgundy PETG and I have not found this colour from any other filament provider, searching high and low.) I am just terrified of breaking my machine since I am still relatively new to this.

    Then don't do this. It may work on casual tests, but it can lead to clogs and the material buckling in the bowdentube or hotend. Your printer was not made to handle 1.75 mm material.

    Thanks for being honest. 
    It is so damn tempting but maybe I am better off trying to get someone else to print it for me on their machine and trade services.  Since I only had a handful of spiralize models I needed printed with this filament.

    I tried it with golden silk filament. You can change the filament type to 1.75mm and adjust some of the settings. It worked well for the most part, but there were times that there were underextrusions. The filament may of been bad, but the surface quality came out nice. BTW I tried it on the UM3 without any modification, except in Cura.

    Just buy some 3mm filament!  You can indeed print 1.75 on a UM printer but you should really make some modifications.  For example 3dsolex has some kits.  But really - just buy the 3mm filament.  Sometimes it's called "2.95" or "2.85" so it's harder to find in search boxes of filament sellers but it's really not that hard to find.
