Hi
I have got my CoreXY to move in the right directions when looking from the front of the printer X+ moves the gantry to the right, and Y+ moves the gantry to the rear of the printer, BUT, when I home Y it does not do it correctly, (see code) HomeX appears to work fine (see code), and HomeAll looks like it work ok again see code.
What have I done wrong? Can someone please correct me in my mistakes. Thank you
Size of the bed 330 x 300 x 400

It homes to the rear left-hand corner, so the Y0 is now set to Y1

The rear is max Y, so it should be Y2 in M574.

Thank you dc42 and sdavi that has solved the homing of the Y.
Its now the Homeall that playing up, it moves the printhead all the way to the from of the printer off the print bed area, whereas when the Y was set to Y1 it stayed at the back because the area limits were clearly wrong, now that putting the HomeZ and Homeall out.

Assuming you want to home x and y, then move to the center of the bed and then do a z-probe try something like this:
