Y axis doesn't set to 0

[burtbick]

I'm trying to determine what I'm missing. Note this is with a controller that is still running GRBL 0.9 if that makes any difference.

I home my machine, then move to where I want the X,Y 0,0 position to be. I click the zero X,Y button and X is set to 0.0 but Y is set to something like -0.07. If I click in the Y box and try to change it to 0 it reverts to the -0.07 value.

I can mill OK, but I'm trying to figure out what I might be missing that is causing this problem. As mentioned X will set to 0, most of the times but Y is not setting to 0. Z sets to 0 just fine every time.

I have another smaller CNC machine running GRBL 1.1 and I haven't seen this problem there.

Running the latest bCNC downloaded from github yesterday.

Has anyone seen something like this, and if so what was the solution? Or is is somehow specific to GRBL 0,9?

Thanks,
Burt

P.S. Other than this minor annoyance bCNC is working great..
