I am at completely at a loss here, I’ve spent the last few hours trying to get the bed level, but nothing I’m doing seems to be working. This is the closest I can get it 0.688mm but it’s way too high, I’ve tried spacers, washers, tightening and loosening the screws, checking the carriage bolts are in properly, nothing seems to be working, could the bed frame itself be warped? Thanks for any tips you can give me.
