Hey, I upgraded my cr10 with an SKR 1.3V board running Marlin bugfix 2.0.x

But it's crashing the X and Y every time I start a print I set the bed size to 300mm as seen in the image but soon as the printer Is done homing it will just take off and crash It acts as the print bed is bigger then it is but I don't know what to do so if you have any suggestions it would be greatly appreciated

... hmmm ... you defined your X_BED_SIZE to 300 and the X_MAX_POS to 320?

That's because the lament switch is 20mm off the bed

... where/what is your starting position in relation to the ref switches?

Arre the steps/mm set correct?

The Y starts right off the switch but the X stars 20mm off the switch.
I will need to check the steps/mm

You need to set the X max to 300
And set X min to -20
This should set the x0 y0 position to the front left corner of the bed.
