I do have my machine and tables both tilted. The table the machine sits on has 3/4 inch blocks under the back table legs and the machine itself has a foam wrist support under the back of it. This is the type of pad used to rest your wrists on while working at the computer.
My cutting table has blocks of about 1 1/2 inches under its back legs. Our friend used a hole saw to cut a notch for the table legs into these blocks so they don't shift.
And, I have another set of 4 blocks, made the same way, that raise the table height 4 inches .... which makes the table a good height for stand up cutting or pressing.
I would not be able to work without these blocks!!!
