What seems to be wrong? The coords seem correct for the position of the toolhead.
The -19? And I thought home was bottom left?
The settings in the firmware dictate where the machine home is vs where the physical stops are. You are correct that the origin position is front left corner on the bed. However, the physical switches (on the Z and Y axis) are on the opposite ends. So when it hits the limit switch, the firmware tells the machine it’s X amount of mm away from the origin, since the machine knows the limit switch is on the opposite side.
As far as X goes, the firmware sets where the edge of the bed should be, so when it bumps the switch, the machine knows it’s 19mm off the left side, so when going to 0, it’ll have to move right by 19mm.
If your home read 0,0,0 where it is now, it would think the plate is already moved back and the gantry all the way down. It would never be able to move into the workspace on Z/Y. X would work, but everything would be shifted 19mm to the left, and potentially off the plate.

So if i understand those mechane coordinates are correct and is ok to use the mechane? I was thinking they where to be 0,0,0.
The reason for the question is that i moved to new house and have t use it since February of last year.
Thank you for your help.
