    Can you share a video of it running g29 so I can see why it's not touching the bed

    Here's what happens after I have manually brought the print head to the "home" position and hit the start button for a print.

    it sounds like it is somehow seeing a z offset still I would check startup code or look to see if there is actually a z offset param being set.

    You wont see an actual offset in the gcode for printing or at least nothing labeled that way it would be a series of commands that do that function.

    I for example use teh auto leveling routine but when it begins to print it end up way too LOW so I have to add the adjustment routine to my start code after the autolevel routine runs.

    The command to run the auto level is G29 and must be run after the axis are homed then I add some additional code after the G29.

    G29
    G1 Z0.5 raises the nozzle to .5mm
    G92 Z0 resets Z Home to be at the nozzles current Z position

    from here on the regualar printing takes place
    I use this setting to get my first layer nailed down


    You may something similar going on in your Gcode that raise the nozzle too high.

    I loaded MatterControl onto another laptop and went through the start up procedure. Things are working but I still have the issue with the home setting. The Z is still too high. I manually get the extruder to the correct home position and start the print. The nozzle moves up and the print starts. I have to manually turn the rods to bring the nozzle down to the print bed. At least I can print things now (doing the happy dance).

    OK. Well the happy dance did not last long. After the test print I tried another different model. No go. The extruder moved to the home position although 3 cm off the bed. When the temperatures finally got to the set points (after bouncing up and down like a yo yo for 10 minutes), the nozzle moved to the start position and stayed there even though the print time elapsed counter was counting down like it was printing.
    Mike, I'll try the firmware up date this evening (BBQ at a friends house, leaving in a few minutes). I'll let everyone know how I fair.

    Cheers,
    John

    OK Mike, this might sound a dumb question but how do I replace the up-dated firmware with the one you sent?

    OK, I down loaded the arduino soft ware and opeded it. I tried to load the firmware following instructions I had download from Melody Bliss. I selected the "Arduino Mega 2560 or Arduino ADK" as suggested. Whan I tired to compile everything I get this error message:
    core.a(main.cpp.o): In function `main':
    C:\Program Files (x86)\Arduino\hardware\arduino\cores\arduino/main.cpp:5: undefined reference to `setup'
    C:\Program Files (x86)\Arduino\hardware\arduino\cores\arduino/main.cpp:15: undefined reference to `loop'

    As you've no doubt guessed, I'm not really a computer software guy and need to be lead by the hand I guess.

    Ahha, a successful print!
    I want to thank Mike for all of his patience and help. I'm sure it would have taken me a hell of a lot longer, if at all, to figure it out myself.
    Thanks again Mike.

    Cheers,
    John

    Mike, are you out there?
    I did a little maintenance on the hot end and now that everything is back together, I cannot connect to the printer (yes, it's turned on). Should I up-date the software before trying to connect?

    Check your wire connectors. Something came loose.

    Mike,

    What did you do to fix sarge5020? I am having a similar problem. I printed 4 or 5 prints OK, then it started doing that home thing and autolevel with the Z axis just going up. I do have the R1 with autolevel, and it was working fine. Without turning the unit off, it went from being OK to doing the up-only thing.

    My issue is not fixed, yet. I have to trace the wires for the extruder to see if that is the problem. If not, I'll have to trace every wire in this damn thing.
    Good luck with yours.

    Mr Fishnose check to make sure the x carriage is fully seated on BOTH sides when you do the leveling to make sure the x carriage itself it level sometimes one side will seat and the rods are stiff enough to not actually allow the x carriage to fully seat you can test this by moving the carriage all the way to the right side and then lightly pressing down on the left side if it moves at all then the left side is not fully seated. Reverse this to check the right side.

    AS STATED BOTH SIDES need to be fully seated THEN you can adjust for the proper levelness of the x carriage.


    IF this is not done one side can seat and the other is not so depending where the carriage is it can slowly bounce up and down slightly during the autolevel this is seen as sometimes it goes up and sometime it goes down depending when the switch is activated.

    When I ran into this the autolevel would adjust up on the right side and down on the left and I found I had about a 1/8 - 1/4 inch gap between where it was and when it was fully seated fixed that and the autolevel worked great afterward.
