    Yeah I thought that could work but after som print I realized that it is not. Even a reduction to 260 for dual head with one extruders does not work. In the latest commit of the profile I changed it all back to X 300 for everything. The problem is that it does not help because you shrink the bed but the origin is still 0 0. Shifting the coordinate system in S3D is not the solution too. I came to the conclusion that there is nothing in S3D I can do to accommodate the reduced movement ability with the dual head. You gotta know the limits when using only one head or both heads...

    Don't change to 300, both extruders have a max. travel of 265 till touching the frame. Normally the slicer should warn you if something is outside the bed, S3D does not do?

    No S3D does not as far as I remember.
    I got something in mind. Didn't have time to work it out. It is hard to explain because of the different reference points that exists. The real origin, the real position of the hotends m and the positions you say to travel to when working with the hotend offset set...

    I change the single right scripts and S3D profile.
    Did this, changed to 260 max.
    But regarding what @PsyVision wants to do, printing with only right extruder I had to change something in the start script for only right extruder.
    That's because when I max the bed to 260 and home with T0 and do other stuff with T0 that would give you only an area of X220 for printing its single right, the same as when printing with dual... That's not ok IMHO.
    You should also be able to print 260 if using only right.
    So all the start code has to go with T1 before, also homing... Then you can print max X260 with only right too...

    For my opinion it's like that: T0 ist travelling from 0 to 260, T1 from 35 to 295, so both extruders allow the same range in X not depending of the homing process. When T1 is at 0, it physically is at 35. So you just have to place your part in the right way.

    Yeah but then if you set the build plate to 260 you have to place your part min on X35 and max over the edge of the build plate...
    If I home with T1 when printing only with T1 then T1 is at X0 and T0 at X-35. That way I always have a X260 build plate and can position the part on that plate...

    Is there a ", autohome, level bed, wait for extruder to get to temp" command I can add to the start script?

    When you go to Prepare > Level bed. That procedure.

    Just so I can save a Goode to SDCard, run it, and the bigbox will do everything else.

    Try Repetier-Host or Pronterface or use Octopi, that's easier, you can send commands directly.
    I guess S3D can do that too, at least send prepared gcodes directly.
    Code would be (with 220 as temperature):
    G28
    G29
    M109 S220

    I'm still seeing the fan speeds set in S3D being ignored, do I need to change a setting marlin to enable GCODE fan control or something?

    Normally not. I can't see what you mean exactly, as I don't use S3D. M106 is fan control, look into the wiki for description. Sorry!

    I think so. Do you possibly use a makerbot-setup?

    Ah, this was it. In S3D under Tools > Firmware configuration. Mine was set to Sailfish.

    Kind of a shame that its not under the Factory file settings but never mind, I can live with it.

    And I made a firmware for the Pro with deactivated auto bed leveling and activated mesh bed leveling.

    CAUTION! I did not test the Pro firmware! Maybe someone can do this and give some feedback?
