UM2X+ build platform moving

[BS1 0]

Hello everyone. We were just fortunate enough to buy our third printer, and decided to get a UM2X+. We are having a strange problem with 50% of our prints where about an hour into the print, the entire glass build platform shifts. Anybody got any ideas? We think maybe the extruded nozzle is grabbing the part occasionally during a traverse, but can't figure out what setting in the software would allow that to happen.

Thanks!

Wow! I've never seen that before!

Well the um2+ series have different clips that hold the glass because the old clips where causing too many fingers to bleed.

Now I guess the new ones aren't tight enough?!

I would put a thin sheet of rubber in there somehow to keep it from moving around. I've had the head hit parts with pretty incredible force before - the equivalent that if you did it with hour fist it would knock the printer a few inches across the table. Maybe 10 pounds for 1/10th second?

So yeah - I would increase the gripping power of those clips. Maybe get some glue stick under them onto the glass?
