It's fair to say that it works fine with the clips' "arms" left intact. The clips themselves are more of a hazard than the arms because they will be the first thing a tool collides with. I never saw a reason to remove them myself. On these printers, they just aren't in any path the robot is likely to follow.
The full 27-page thread talks about a range and variety of printers, and it is over that range I addressed in my post. This thread is referenced in many places across the 3D community as a primary place where the history of PEI beds, getting them to stick and getting things to stick to it, can be seen in full. MANY 3D printers on the market are the kind where the y-axis moves the whole bed. For example, the TAZ4. On the front, back and left sides of the bed, a dangling arm on the underside can snag on the y-axis belt, the stepper motor pulley, the metal frame, and even sometimes the x-axis wiring. In such instances they represent such a clear and present danger I thought it bore mentioning. You know...the way people in forums do. Help each other out and sh!t like that.
But apparently many here believe the world is only populated with their beloved Orion delta-style machines, and all advice for others is dismissed. I guess I must have missed the big red sign proclaiming this a phase-III online community, where outside new opinions are denounced and castigated before discovering their truth; where a vocal few insist on making rude comments to knowledgeable people looking to contribute. In case you're wondering, phase-IV online communities exist when people stop contributing because this exact kind of push-back makes it not worth the time it takes to research, write, edit and post. That phase is called "imminent community failure". No worries, I'm not new to seeing this phenomenon play out. Just so you know, I tend to have backed up my posts with a full examination of the facts before posting, so no, your blanket statements in fact do not diminish the truth of my statements.
Okay, so here's few more reasons for those who won't care anyway: the arms are heatsinks. Having problems with the edge of the bed getting cold? Well guess what: those arms dissipate heat too and in a small way add to your problems. How about it just looks better with them off? I suspect the number and kind of reasons could just as well be endless, but a bunch here believe that nothing ever said will ever convince them to try anything that would ever challenge their long-ago made up minds. Fine...you have fun with that. It doesn't matter whether you believe me, within six months you'll know I'm right.
Do people really leave a #2 Phillips screwdriver in every screw they put in? How about a hex key in a socket-head screw? Do you leave the empty oil container under the hood of the car? Do you drive off with the gas-filler hose still in the side of the car? Wait...I'll bet you leave that plastic protective film on all your electronics, don't you? The idea that the installation tool is not to be left in place is not normally a foreign concept to technical people, so it's hilarious how much push back some people are giving. Sure...Heroin won't necessarily kill you every single time either...so go for it!
For that non-zero population to whom the advice applies and is important, well now they know. For the naysayers, just so you know, the existence of that population proves that your assertions that somehow the arms can always be left on is nothing more than a really obvious logical fallacy. Take 'em off, or don't, I don't care. I don't leave loose screws in my machinery, no matter how likely it might be to not be a problem. And when I see a preponderance of people making what could be a damaging mistake, I for one am willing to say so, unbowed by the protestations of those to whom the advice doesn't apply.
Silly silly people.
One common thing about the prints detaching from the bed is that they all detach from the direction of the Y-Z axis - so quite likely a levelling/adjustment issue along with poor bed adhesion.
Thank you so much.
