Thank You Hood, That Worked... Perhaps you can help me with another problem... My MAchine work area is 42" by 26". The 42" being the Y Axis and moves left to right... the 26" is the gantry and moves away and to me X axis... on my key board, If i hit page up the Z goes down, if i hit the the direction keys left or right. the Y moves the oppisite direction. can this be corrected some how?
