    All you will need to update is the step settings for extrusion. E3D has a suggested value in their wiki guide for assembly. http://wiki.e3d-online.com/wiki/Titan_Assembly
    Have you ever updated your firmware on the robo before? If not, you will have to go here http://guide.robo3d.com/Wiki/ROBO_3D_Firmware_Release_Notes and download the appropriate firmware version. Also download the ardunno software from www.arduino.cc. Once installed you can then edit the firmware and load it.

    I would suggest doing an extrusion calibration to make sure you fine tune this setting.

    If you want to skip firmware updates, you can change the values using commands. Tom explains that as well in his video below.

    This video from Novice Expert shows pretty well how to do the firmware update.. ignore the LCD parts of it but he shows how to get arduino and whatnot.


    Essentially you want to find this line in the Configuration.h file, and the last number is the extruder steps you want to modify for the titan.
    Code:
    #define DEFAULT_AXIS_STEPS_PER_UNIT   {80,80,800,406} 
    By default mine looked like this
    Code:
    #define DEFAULT_AXIS_STEPS_PER_UNIT   {80,80,800,723.38}  // default steps per unit for RoBo 3D R1
    E3D reccomends a value of 456 for the titan but doing the measuring per their instructions and from the Tom's video that Danzca6 posted I found that 456 still extruded way too much.. I ended up on 406... your results will probably vary. And mine may not even be perfect ( damn it is hard to measure that with the robo's cover on lol... I would reccomend taking care of this part while the robo cover is still off. )

    Must be a very relaxed Titan.

    Maybe that is why it has the munchies for ABS

    Sorry...I should wait for the wound to at least scab over before picking at it. How is that issue going? I see that E3D has got involved over the weekend.

    They finally got back to me today about the idler lever issue I had with it being too tight and said it must have been a missed step reaming the holes in production. So others might have that issue as well. Doing a hand reaming with a 5mm bit did the trick for me last week.

    Looks like they also posted an issue with a last minute design change they did causing problems with 3mm filament usage and a new idler lever might be available in June according to their sales page http://e3d-online.com/Titan-Extruder.

    Looks like they have had a few issues out the door. Hopefully they will have it all dialed in soon.

    Reverse the plug for the extruder where it connects to the RAMPS board.

    I am running four of the R1 plus models and have all the parts to do this to all four, just want to get my head around all of it on the first one before updating the other three, I am running the E3D V6 hot end on them as well. can we turn up the max temp above 255? I see a bunch of settings in the Arduino for temps...

    so it does not require updating the firmware to do so?

    I am so confused... I have updated the firmware with a number of 420 just to see where I am at. no matter what I change the number to and "upload it" it still is extruding 175mm using Tom's Gcode of G92E0 to zero the extruder and then sending it G1E100F90 to extrude 100mm, I am actually extruding 175mm. any ideas on why? and as far as temp settings go do I have to update for just the normal 30W E3d V6? I am so lost guys. I am new to the code stuff and using the Arduino application. I know it cant be as hard as I'm making it.

    I have double checked everything and researched on here how to update firmware ect... the Robo is still extruding 175mm no matter what number I put in that area. the Arduino interface says it is "done uploading" everytime, and still no change when I go into Simplify3d and enter the Gcode to zero the extruder and then run 100mm of filament at a speed of 90

    #define DEFAULT_AXIS_STEPS_PER_UNIT {80,80,800,406}

    THIS IS WHAT I HAVE IN THE CODE LINE

    Well, you need to change the 800 to something less.
