Questions in the file config.g

[xiaoxiaobai1986]

Hello everyone, when I checked the M208（M208 X-13.75:313.75 Y-44:341 Z-0.2:305） instruction in the config.g, I found that the minimum limit value of the Y axis was -44, which is inconsistent with the results I measured in CAD. Do you have any opinions?
In my opinion, the most effective Y-axis should be equal to 40.44（82.19+2.5-44.25）

1）ZProbe Center to crossbar_6mm_for_400_mgn12_rail side

2）YAxix endstop（nominel operating position）to build plate edges
