How to change the MK3S print plate dimensions?

 I changed the print settings for the print plate in the Prusa Slicer in x = 250, y = 216.5,  starting position x = 0 y = -3. The values ​​are recognized by the slicer. The gcode is generated and transmitted to the MK3S. Unfortunately, the printer does not accept the values ​​set for the printing plate. It is still at x = 250 y = 210. Prusa Support said, that ist hardware coded. But I've read in the web, that it's possible to change the print plate dimensions. I need this only for only one 3D-print.

This can be done, but doesn't always work for every one. Not sure why. Maybe depends on the firmware used.

Have a look here: https://forum.prusa3d.com/forum/original-prusa-i3-mk3s-mk3-how-do-i-print-this-printing-help/need-to-print-o216mm-footprint-on-i3mk3s/

You need to go Y- with knob, "settings", "move axis", "Y" and check your "max" Y minus, that´s the number you type in "Origin"
Let's say you could go to "-4", then you type "4", positive, in Y-origin
Then go Y+ as long as you could, let's say your max is "213"
Add 213 to 4 ->217, type "217" in Y "size"

When I tried this on my machine I typed in bed size "215", origin "3" and the biggest part I could make with those settings was 214,9

Of course No Skirt or Brim, And adjust primeline

Prusa i3 MK3S+ FW 3.11.0 (kit dec -20), PrusaSlicer 2.5.0+win64, Fusion 360, Windows 10

@Ringarn67

thank you for your hints!

I'm also happy to found a solution in Baklin's ini-file in the given link above (216mm-mod).

I'm currently working with MK3S-firmware version 3.10.0 and Prusa Slicer Version 2.3.3
