It doesn't bother me and I just hold the arm when I turn it off. They include a visible warning about this in the package but it could perhaps be considered a flaw. The pre-production and early production models have an extruder arm that falls when the printer is powered off.

To point out a couple things that didn't really fit into my review. They replied quickly and seemed responsive to it so fingers crossed the proprietary deterrent will be lifted soon. I recommended they open source the firmware/software asap (although there are open source smoothie boards available for it now), pick up a US distributor (ships from China) and either include the heated bed or make it an addon purchase for more visibility. After my review was complete, I e-mailed them some suggestions last night to address the low points that most complaints seem to be geared towards. I would absolutely agree with that, I have been blown away by the level of interaction and support they have with their community. The consensus of most owners is they have done a very poor job of marketing it themselves, although the product quality is superb. Overall I think this is an absolutely fantastic budget 3D Printer. where other owners provided some suggestions to help make it more comprehensive, offering additional items for the pros/cons category and correcting mistakes I made. I posted it on the Facebook support group first for feedback. There have been some people asking questions about it here, so I thought this may help someone searching for more info.

I finally finished up my review on the Cetus3D Printer yesterday.
