I ordered the Maker Select on June 5th from Amazon received it last night. It has thumb screws and lock nuts on the build plate. Thumbwheel Also new bearing blocks that no longer rub on the belt. Bearing BlockI also printed my first benchy with it last night Benchy and while it needs some work (I think I was printing too hot) I was impressed at the quality considering I have done no dialing in or any modifications.My only complaint is I think the y-axis bearings are bad I hear a clunking/grinding noise when I move the bed and it is very jerky. So I am planning on ordering some new bearings and hopefully that will fix the problem. http://ift.tt/25OxeGW
