Most turning errors come down to the accuracy of the x axis homing, a small error is doubled.

You could try swapping the Active low to high and try again.

What happens if you type this into MDI and touch the wires.

If you use inches

G31 Z-2. F5.

For metric

G31 Z-50. F125.

Super as usual.

I think you have the values the wrong way round :-

If your machine homes to the right back corner then the values are :-

X Max 2.00  X Min -2200.00
Y Max 2.00  Y Min -2300.00
Z Max 2.00 Z Min -80.00

If your machine homes to the front left then :-

X Max 2200.00  X Min -2.00
Y Max 2300.00  Y Min -2.00
Z Max 2.00 Z Min -80.00

It could also be that you need to have a G54 command at the start of the new tool to update the absolute position.
