Yeah I’m positioning this as a feature request. A QCW feature that helps keep the machine frame square. I think it’s something we could make ourselves once we have a square machine, but just as a pay it forward type of offering.
Did you mean the screws at either end of the x rail that can be used to (marginally) adjust tramming front to back? I’ve messed with those but have not adjusted any screws on the z rail yet.
