    Mach3 reversing x-,y- to x+,y+

    Would like to say that all the help I have received here has been outstanding.

    With the way I stand at my table I would like x,y 0 to my left. That way x goes left to right 0 to +1250, y goes away form me 0 to +660. I have tried to find the answer at YaHoo group and I figure I will retire again before I find it in there.

    If I tell the X (gantry) to go from right to left Mach3 counts 0 to will say -900. I would like it to count 0 to +900. The same with Y I want it to count up as it moves away from me. 0 to +660 not 0 to -660.

    Modify the setting DIR in Mach (in ports and pins) to [active low] or [active high] to change the direction for each axis.

    That is correct for right to left movement.
    Left to right should give you 0 to +900.

    It seems like you want the axis flipped. Maybe you're looking at it differently, but I thought normally, the axis were assign how an actually graph is, from 0,0, up is positive y, down is negative y, left is negative x , right is positive. It's in relation to the part moving from the head, if the table move away from you in the y, the head in relation to the table is actually moving down. Look at the table as if it's the head moving around the table and the table nos a stationary graph, how would you move to positive and negative. You can flip your axis around in the settings, I had them flipped on accident, but why do you want then inversed? When you cad something it will cut it inversely as well, be sure you know how to set uo your work accordingly. I have by axis to machine exactly how I draw and zero my part on screen.
