2 days into a 5-day build, I came home from work and found the build ruined because the build plate had slipped.

I'm using a Raise 3D N2 Plus printer, with the standard glass build plate that comes with it, attached via 4 clips: two stationary ones at the back, and two standard binder clips at the front, which shipped with the printer, which hold the glass build plate plate to the heated surface beneath.

The left-side clip had come off of the heated surface, remaining clipped to the top and bottom of the glass plate, and the whole thing slipped an inch or so. I immediately canceled the build, and I can start another one, but before I do I'd like to know how this happened and what I can do to prevent it from happening again.

What typically causes the plate clips to come free? Is there anything I can do about it? Will adding more clips around the edges help? I'd really prefer not to ruin more builds if I can help it...

Your nozzle may have caught up with the print somehow pushing the binder clip off by moving the glass slate.

Apparently this is a more common problem. Try adding more binder clips, this has been reported to help preventing shifting.

Maybe with some ingenuity you could develop your own fastening system depending on the bed. Alternatively, you could make the underside of the glass a little sticky so that it does not move easily (a little PVA based glue maybe or hairspray, I've done that with my mouse mat with 3DLAC :) which is now not slipping from the desk).
