Home Position Keeps Moving

[Wheelz]

If I'm burning multiple parts, or if I interrupt a run, my home position is altered by X:11.4 Y:5.3 every time.
I have to move it back and Set Home Position again. If I forget to, obviously, I get double image cut.
Why won't it hold my home position?

Have you accidentally saved an offset?

If so, click "Clear Grbl Positions" in the Machine menu.

Certainly not deliberately, but I guess I must have somehow.
"Clear Grbl Positions" fixed it anyway.
Thanks Zax.

BTW. If I reinstall T2 to restore it to original settings, will that affect my registration?
It's just that I've done too much tinkering with settings to see what they do and some processes aren't behaving as I'd like any more and I don't know what I've done, lol.

If you use Machine Home and don't have home switches it will create a fixed offset, so every time you home that offset is applied.

No it won't but there's no need to reinstall, you can restore defaults in the Help menu.

It only affects T2Laser settings, to reset your laser use the Reset Grbl Parameters option in the Machine menu.
