We have an older PR96 unit (yes, it still running!) that we are considering making a few simple and one major structural upgrades to. It spent years working hard full time before we acquired it several years ago. We mainly use it to introduce high school kids to basic CNC (they just eat it up after they get over dealing with a DOS based system!) and for occasionally making parts for other personal projects .
The most significant change we are interested in is tilting the entire frame along the X axis. Basically, tilting the unit so it resembles a wall mounted panel saw. We would add counterbalance to the Y axis, and change the roller configuration on each axis for the new load. This configuration would significantly reduce the required floor space and ease loading since most of our material is stored on edge. Any drawbacks? Thanks!
