Bed doesn't heat without lamp over it The bed on my prusa i3 doesn't hold it's temp at 110 degrees C once the print has started. I have a reading lamp over it while heating up to help it heat faster but when I take it off the temp starts to drop. It can't hold it's temp without help from a reading lamp. I can't have it over the bed during the print because it would hit and bump into the print. The bed hovers around 90 degrees but doesn't stay at the target 110.
