    I touched the E driver on electronics and it's very hot. Is it the drivers or fan problem? Others seems cold. Or maybe it's hard to extrude for motor?

    Check the ekectronics assembly guide on the Ultimaker Wiki. On the bottom you find instructions about adjusting the stepper current. If you are lucky then the driver is still ok.

    Also check that the heatsink is attached and that the driver and heatsink are getting airflow from the fan.

    That's a sign of too high current.

    Ok, maybe it's time for an off-power test. If you switch the printer off and slowly turn the extruder wheel, how does it feel? Smooth or very rough as if something is broken inside?

    edit: make sure you're turning the driver potmeter into the correct direction! Otherwise you can destroy it quite easily!

    I think the drivers were originally done by pololu and then copied many many times. They have distributors in Russia:

    http://www.pololu.com/distributors#russia

    These are compatible with the ones that come with the printer:

    http://www.pololu.com/product/1182/

    You can upgrade to the black version which handle more current or the DRV8825 which handles even more current.

    http://www.pololu.com/product/2128

    http://www.pololu.com/product/2133

    The upgraded versions are both pin compatible with the first one and those in the printer. However, the DRV8825 version defaults to 32 microsteps whereas the original and black version default to 16 microsteps. For the DRV8825, you need to alter the jumpers on the shield so that it is in 16 microstep mode or update the firmware steps/mm.

    However, for any of the three pololu supplied drivers, you need to solder the pins/headers on and they do NOT come with a heatsink. You can use pliers to remove the heatsink off the driver you are replacing and then scrap and clean and then use a thermal adhesive like http://www.arcticsilver.com/ta.htm to attach to the new driver.

    With all that aside, the question is why is the driver shutting down? Did you check that the stepper is free and easily moved after removing the filament? can it feed the filament through the Bowden tube until it gets to the extruder? You should be able to easily turn the large gear by hand (slowly) without the filament and then fairly easily until the filament gets to the extruder.

    Note that you want to turn the current down if the driver is shutting down due to heat. Refer to this to know which direction to turn. It shows the direction for increasing so you want to do the opposite like a 1/16th of a turn and then test. stepperdrivers

      • S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
        (Sorry, was out of office when this released)

        This update is for...
        All UltiMaker S series  
        New features
         
        Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.

      • Ultimaker Cura 5.6 stable released
        Cura now supports Method series printers!
         
        A year after the merger of Ultimaker and MakerBotQQ, we have unlocked the ability for users of our Method series printers to slice files using UltiMaker Cura. As of this release, users can find profiles for our Method and Method XL printers, as well as material profiles for ABS-R, ABS-CF, and RapidRinse. Meaning it’s now possible to use either Cura or the existing cloud-slicing software CloudPrint when printing with these printers or materials
