    I finally have my big box up and, after a lot of work, in tram.

    I now have an issue with setting the z offset. I might (probably) have screwed it up along the way, but I no longer see the "Z Offset" in Marlin.

    In addition while trying to grease my Z threads I can only get the build platform to move about 1/2 way down. It still reads that it has moved 280 mm but is not sticking or anything, just a deliberate stop.

    I am kind of thinking the firmware is goofed up at this point and I need to reinstall it.

    Any Suggestions?

    In the build instructions I think there is mention of it getting the zero position wrong and of new firmware.

    I didn't do this and my Z axis sometimes does odd things, the ref is here in the WiKi.....

    Please let me know if this solves the problem :)

    Thanks for the help guys. I have a dual so I am missing the Z offset line in the firmware (thanks Greg), the crashing into the glass and the bed not lowering to the full 280 had me stumped. Turns it was a combination of things. I did the bed leveling again and the head no longer crashes into the glass, and I understand the 280 resetting to 180 is a Marlin bug so I think I am good to go with that understanding.

    I have final calibration for the extruders and we will see how it goes.

    Thanks again for the help.
