Ok I see now where you are getting confused, it is because the Jog button LEDs are above the Limit and home switch LEDs and you are thinking the columns are all X and Y and Z etc. That is not the case, all LEDs relate to their individual function and are not in columns of X Y Z etc.
Ok there is no such thing as M1 and M3 on Y and A columns M1 is X axis switches and there are three M1's. M1++ is X+ Limit M1-- is X- Limit M1 Home is X Home
Same for the rest, ie M2 is Y, M3 is Z, M4 is A
I think I half know what you are meaning but to make sure attach the latest xml, I will simulate your switches and post screenshots of what you should see. Hood
Are you looking at the machine coords as it is them that zero when homing. If you are looking at an offset you have set up (normal view of DROs) then you will not see them zero as they will show the offset. Hood
Oh and to answer your question regarding the Jog, it is if you have External Jog buttons, when you press them the LEDs will light. Now note I say external Jog Buttons. This is not the Keybopard buttons, this is real buttons coming in on Inputs in a similar fashion to your other Inputs (Limits etc) You dont have any external jog buttons so you wont see the LEDs light.
