Hello.
I'm trying to do the same thing. I have build a simple lathe model, because I want to learn how to use the software.
My tool is located on the other side of the center, compairing to a traditional lathe, so I want the up arrow (X axis) on my keyboard to move the tool away from the center and read positive DRO value.
Everything is working fine, but DRO is reading negative.
Checking and unchecking the X axis DIR LowActiv is not making any difference. Up arrow is always negative.
Any Ideas how to fix it?
