And when you use right side and left side they are at the ends of the material being cut not on top correct? That’s the cumbersome part. The space between the 2 blue squares is the length of the material being cut.
Not certain I truly understand your question but I'm going to give answering it a shot.
The squares come off and go on so easily I do not find it an issue. I find it areal advantage. This eliminates all the torque on the guide rail.
Most times you'll need to clear the cut table for the next piece. If not just slide the assembly forward. Back to the clearing the table----remove the square/arm assembly(s), set aside, lift rail, clear table, set new work piece, place rail randomly, pop on squares/arms, set stops to edge, cut, repeat.
