Hi guys, newbie here, my basic 6 Axiom was homing fine out from the gate, but I mistakenly hit XY-0 button while in machine state when I thought I was setting my work origin. Now when I home my machine it trying to go beyond the machine's limit. The DRO's on the HHC for all axes are wrong. Does anyone know how do I correct this. I never backed up my original data like a knuckle head I know, but is there another way to fix my homing error without having to wait for the Restore file from Chad? Thanks for any help, Mindstate

You're in the "machine coordinate state" and pressing xy-0 has no effect. Press Menu+1 at same time to enter the "work coordinate state" where you will be able to set your work origin. This will show 1X, 1Y and 1Z.
I totally get what your saying, but some how my machine coordinate state was changed, because my DRO's on my HHC do not match up to where the X and Y actually are. In other words when I home my machine and it hits the limit switches the XY axes don't stop and reads 0.00 like it once did, now it wants to keep going because the controller thinks the machine has not reached home and it has. I don't have any issue setting up the work origin. So I'm sure I did something to alter my machine coordinate state, which seek desperately to fix. So I hope my explanation clarifies my situation a little better. Thanks
Mindstate, Just so I can Understand more clearly, are you say the when the machine hits the limit switches it does not stop ?? The motors are trying to keep moving... Or is it that the numbers on the DRO are not 0,0 This is where my confusion about your problem is comoing from.
Yes, you got it Mike ! when my machine hits the limit switches it does not stop. The motors try to keep moving. That's it in a nutshell. And the DRO's don't read zero when the machine is at the home position they read as if the machine is far away from home, understand? I hope someone does! Mindstate
First, you state..."when my machine hits the limit switches it does not stop. The motors try to keep moving"
Which axis are you referring to? X, Y, Z or all three? Would seem odd that all three are not homing at the same time. Have you inspected each axis homing switch and the metal tab that triggers each switch for any screws that have become loose? That would be the 1st thing I would suggest.
Second, you state...."DRO's don't read zero when the machine is at the home position....". How did you get to the home position with the aforementioned problem affecting the homing operation?
OK, assuming your machine is in 1 of 9 available work origin states and has homed correctly, you will not see 1X 0, 1Y 0 unless you have set your work origin to also be at the home position. For example.....I have a permanent fixture placed at the rear of my machine. When I "Home" my DRO reads 1X -424.600 1Y -778.200 When I press Origin to send the machine to the center of my fixture, all is well and the DRO now reads 1X 0 1Y 0
This is very useful information to have if you use fixtures. I recently updated my data file and lost all my origins. No biggy. After homing, I sent the machine to X 424.600 and Y 778.200. Bingo right at the center of my fixture and all is well.
It's a deep rabbit hole where you're going. Been there myself. You will make it out eventually and know more for it
