Problem with Software/Settings ????

If the axis are at the home position and I then move any axis the DRO will read negative which is correct and as it should be but if I reverse the "X" and "Y" axis as you say then if the machine is homed and then the axis are moved the DRO read positive which is not correct if it were correct then my other 4 cnc machines are all incorrect.

IF you set up work 0,0 to be the lower left of bed travel facing the front of the machine THEN all moves WILL be positive.  WHere you setup Machine HOME is a totally different thing to where you work from.  I see you refhome to the top left. that sets Machine zero as you say then all move in MACHINE corrds will be neg. BUT you don't WORK in machine coords you work in work coords.(;-)

Note my earlier statement IF your mill is a bed or knee mill it will move the axis BACKWARDS to a GANTRY setup for the same tool positioning.  SO your setup cannot be the same direction wise to your gantry mill/router

Just a thought, (;-) TP
