Hi, everybody!

I have just installed a new "brain" in one of my machines (old model A, still equipped with QC) and wanted to recalibrate it, before I even start with any project.

I can measure the board and got difference of around 0.05" on a 30" board. Not much, but anyway... I wanted to re-calibrate. Strange enough - I cannot even get into the Options menu. I press 0, but nothing happens.

What is the cause? ...and the remedy?
