Just take a lot of time and care on initial setup on your R4512 and you’ll love it. Out of the box mine was out of adjustment in just about every way possible. Once i got it set up properly, its as sweet as can be. Also, don’t go with thin kerf blades. The riving knife will bind up in the kerf on a thin kerf blade. I’d also highly recommend a digital angle gauge for setting blade angle as the factory angle pointer is not that accurate and is easily knocked out of adjustment. A Leecraft zero clearance insert is also a good thing to have. I hope you enjoy your saw as much as I do :-)
