Auto Home - Minimal X position

After Auto Home is finished, extruder is on position x=12. If I will try to move it more left, it does not allow me to go less then x=3.8. If the GCODE sends the extruder to less then 3.8, it stays on 3.8. It never goes to 0. This is  not an issue, if you print from the middle, it is just a limit of print bed. But if you have a gcode starting at 0, it is printed wrong. 

I am not able to move to x < 3.8 using gcode or printer menu command. Even if I setup different start coordinates by G92 command, printer still remembers it can not go bellow 3.8, even if in fact it is in the middle of the print bed.

Yes, easist way would be to move the object and not to start from 0, but the gcode does not comes from PrusaSlicer and I can not influent the object position.

Any ideas?

It would help if you said what model printer you have!

RE: Auto Home - Minimal X position

Isn't the 0 position of X (and Y) axis defined by the limit switch?  

I think that the firmware will assume that x=0 (or y) is outside of the printable area and refuse to print from 0. 

Sounds like you would either have to modify the gcode or the firmware to me.

I think the same. I do not want to change FW because of time to time engraving, so I will have to modify the gcode. Currently I am placing a small dot 5mm before the object, so that the main object coordinates in gcode are a bit offseted.
