axis moving to the end but LCD says half of the intended length

Hi,
My printer is working well, with the bed dimensions being 210*210, the probe offset being set appropriately, and all hardware and cabling appropriatelly pluged and fixed.

Issue is when any of the axis moves from the endstop to the end of the axis, the endstop being being zero, the lcd is reading half of what the end of the axis should be, So the dimensions of the printer should be x210 x y210x z230, instead, when each axis is at its max the axis readings are x125 x y125 x z140

please help, i have tried to double the steps, and halfs the steps/mm, yet it is still not going to the full extent of the build.

I have Z Safe home enabled. using mgn12 rails, using the einsy rambo with modified marlin from the prusaowners github page.

I can post the modified github page tonight.as well as my conguration page.

Can some one also illustrate the bed and movement settings in a nice illustration

please help

check your steps/mm settings in firmware is not being over written by the eeprom.

use M503 to display the settings it is using.

or M502 to reset settings to the firmware settings, then M500 to store these setting to eeprom.
