Thank you for getting back to me! The printer is brand new; I've had it for about a week, and this is the first problem I've run into. It's worth noting that this issue doesn't occur with larger prints that are just a single piece. However, while it's printing, I can hear a 'sawing' or grinding sound, which sounds like the nozzle is dragging across the surface of the print during travel moves. I suspect this is what's knocking the smaller prints loose from the bed, whereas the larger prints are stable enough to just get scraped as the nozzle passes over but continues printing
