Bug Description

I'm using MEGA_P_DGUS_v1.4.2 on stock Mega Pro, it tried to (can) go further after touching the Z-limit switches when jogging the Z axis, the issue not exist on the X/Y axis/switches. It was almost crashed the glass when first time homing, and homing correctly worked after reset but the issue persist when manually jogging. Can you please fix it?

Steps to Reproduce

Go to the axis control on the touch menu or Printer controls in Cura and lower the Z axis below 0.0.
