So while building, I had an issue that only one screw on each Y front bracket really took hold. The other screws thread just didn't find anything to take against - as in the hole was too large, I could just push the screw in all the way. On one side I could get a larger screw to take, but with a largeish gap between screw cap and frame. On the other side I got nothing. The printer itself is printing, but I seem to have a small amount of ringing. The name of the boat is not discernable and the vertical indent on the starboard hull isn't really vertical. Nothing major, but enough to annoy. I'm guessing the ringing is coming from the Y brackets not being as tight as they could be. Any hints on what I could try to get the Y brackets tightened further?
