Haven't taped mine down yet, though -- thinking about using velcro tape, in case I need to remove it for a really tall print, but haven't procured any yet. About 95% of the time, not being attached works just fine, and my bed doesn't normally drop anyway. Though for that ca. 1% case where the spring isn't in place AND the bed drops, assuming I'm within earshot when the print ends, it lets me know it's one of the rare exceptions.
