predefined printer limits

I get and error saying the g code will not fit inside my printer limits - I say to print anyway and it comes out fine. 
What printer limits should I use? I have an orginal Prusa MK2.5S. I have put in the proper bed size, what am i missing?


  • Reason is the prime line prusa slicer profiles generate. They are at y=-3. YOu need to say ymin and front in bed shape are at -3.5 and not 0. Then the message disappears.

    You should also tell server not to use it for size computations. In start gcode of the printer profile put the prime line with @nosize/@size to make renderings better placed.

    {if not has_single_extruder_multi_material_priming}
    ;go outside print area

  • thanks for the help
    if I put the ; infront of the command, will it still work?
  • Yes @ and ;@ both work. ;@ was added so if it gets copied to other osftware or sd card it just gets ignored as comment. 
  • Thanks again!
