  1. Glad you have been irritated by the same problem!


    Trying to change a print core - say from an A0.25 to A0.4 - and a filament that isn't compatible with whatever was there beforehand can get you into a knot that can only be untied by switching off and rebooting. That seems remarkably primitive compared to everything else this machine can do.


    If the menu loop reaches a dead-end then I agree it would be nice to have a Return option that allows you to restart that loop and, say, change the order of the new set up to avoid the dead-end.

  2. Just bought one of these on the basis of your several comments. It's good.


    The assembly instructions take a bit of following but do work, and everything fits very accurately - impressive.


    I'm using a number of awkward materials and hadn't appreciated how much an enclosure assists with keeping ambient conditions stable. Well worth the money.


    Thank you, gentlefolk.

  3. I have an Ultimaker 3 which earns its keep well. I run quite a few different filaments, some of which need relatively high temperatures. I've now had two print heads fail because of the transparent plastic lever degrading, so that it crazes and splits at the screw head.


    I understand this isn't currently a replaceable part - a shame - but I wonder if others have had similar experiences?


    If so, does anyone have ideas as to how the thermal stress on this point could be reduced?
