    Everybody relaxed now that @Alex9779 is happy? I can now continue with gluing the nuts into the little black beasties and ordering the Titan dual upgrade that was just announced so that I don't have to build the current dual head.

    Don't do that, I'm about making a "tut" on youtube showing how to put them easily without glue!

    Too late, 140 done! But, it was not too onerous as it kept me out of trouble! :D

    Sticky, yes but I would like to see the Problem and Resolution in post 1 or 1 and 2.... It's nice to read and follow the quest... but for finding the resolution in a almost #100 posts thread is kind of not nice.
    That's why I preffere stuff like stackexchange.com over forums.
    Or a Wiki article.

    While we are talking about Calibrating the E steps, can I ask something else but related ? The build manual only shows how to set it for 1 motor, how about dual ? I could not find in the lcd menu how to set the second motor. Anyone can help me ?

    If you are using the script on the SD, I think there is a second one. If you are using OctoPrint or S3D there is an option to set the active tool head. If you are using the LCD to move an axis (under prepare) there is an option for each Extruder.

    Marlin does not support different E steps per extruder at the moment. But when printing with dual you can change them each time in the tool change script.

    Not to raise the dead, but when I went to print with Colorfabb XT I am way over extruding I have my multiplier at .86

    @Alex9779 do you notice anything like that when comparing XT to or filament?

    Also how are your vertical circales or steep overhangs, I have been having some issue with that aswell with XT.

    I'm extruding XT at 0.9 extrusion multiplier (non-Titan extruder).

    The only trouble I have with XT regarding steep overhangs is that, with it's relatively high nozzle temperature it's difficult to use much fan without encountering thermal runaway. And fan is what makes steep things work well.

    Helps to orientate the part to catch as much fan as possible on the relevant feature.

    I encased the heat bock with 1/4 wide Kapton Tape, I can now run the fan at 100% with no issue. However the overhangs still could be better.
    I only bought the filament for printing the 1.1 so I will just leave it as is instead of fiddling any more with XT, too expensive lol.

    Have you seen RichRaps latest video? it shows a silicon boot that goes over the E3D V6 block, this helps with stopping the filament sticking to the nozzle but also help insulate the block and thus I guess help prevent thermal runaway.

    Haven't seen the video but I believe on reddit Sanjay said it would be weeks if not months before its in the store. I plan on making one manually based on this until I can buy the real ones http://www.thingiverse.com/thing:1520261

    I am struggling with the esteps on the Titan. When doing he adjusted calculation I get a wildly different number than the standard one. I noticed others came up against something similar and wondered if someone had a solution.
    Also could someone point me to where the SD card files are stored?

    The calculation is theoretical. There is an detailed formula here. But the best way is to extrude and measure... Just extrude slowly so the pressure in the nozzle doe not counter the extrusion length. For a real raw value you can measure without nozzle but extruding with heat and melting filament and at least some pressure gives you a more practical value when actually printing....

    I have been trying to calibrate it through the volcano but I come up very short on the 100mm. Yet I seem to be able to print nicely afte upping the flow rate as required. I just wish I could get the esteps sorted.

    I concur! I too have not had consistent results. Using RC3 on a BB-1.0 Dual with dual volcanoes.
