Did you check how far it moves with just jogging? If you tell it move 2 inches…what is the result? If it is less, then you probably have to recalibrate the Grbl settings. Instead of writing the same thing over…see my post here. It is the 3rd one in the link. You probably need to adjust $100, $101, and $102. It is a ratio of what you want to what you get multiplied by the current number for that particular setting. You will need an accurate measuring device like a machinist rule or a digital caliper. I just replaced my x controller and computer and had to redo this myself.
