Making the frame square

[JAZZCNC]

Rob don't get obsessed with squareness of the frame because mostly it's not critical and just measureing across the diagonals will be enough. Whats VERY VERY important is that you don't set the frame in Twist.

Reason why frame squarness isn't critical (To some degree depending on design!!) is because it just holds the rails and the Gantry rides on the rails so you affectively set "Cutting" squareness with rail and gantry alignment not the frame. It's also why Twist is VERY bad because rails sit on the frame and Twist means they won't be on the same plane. This is why Epoxy levelling is good has it levels out any twist.
