  1. I have used these for about 2+ years and have found them to work very well on my UM2+ - certainly reduce the noise etc. Design by @UbuntuBirdy who used to be on here.

    https://www.youmagine.com/designs/ultimaker-2-2-damper-feet-12-55

     

    I assume they would work on a UM3, but would be worth checking the dimensions of the grooves on the mounting area.

  2. Right, I've just checked and running 17.09 firmware on my Mark2 with Cura 4.4.1 and normally just use the UM2+ setup with no problems by just loading Head 2 prior to start the print.

     

    Here is my start/stop script I use which may be helpful for you - Gcode flavour Marlin (Maybe it's this that helps? - as can't really see anything else out of the ordinary!)

     

    G21 ;metric values
    G90 ;absolute positioning
    M82 ;set extruder to absolute mode
    M107 ;start with the fan off
    G28 Z0 ;move Z to bottom endstops
    G28 X0 Y0 ;move X/Y to endstops
    G1 X25 Y25 F3000 ; bring extruder to the front
    G92 E0 ; zero the extruded length
    G1 Z0.3 ; lower
    G1 X35 E20 F225 ; purge nozzle with 20mm of filament
    G1 X45 Y25 F2100
    G92 E0 ; zero the extruded length again

     

    M104 S0 ;extruder heater off
    M140 S0 ;heated bed heater off (if you have it)
    G28 X0 Y0 ;move X/Y to min endstops, so the head is out of the way
    M84 ;steppers off
    G90 ;absolute positioning

    navigator thanks for the reply I di exactly that spent ages with different tensions on the paper I'm gonna try this again if still cant get it to stick then I will download ZOffset tweak and try that,, thanks for all the advise appreciated.

     

    When doing the Z distance in the Mark 2 area in the maintenance menu  for head 1 & 2, you do not need to use paper - just do what it says and get the bed to just touch the printer nozzle!!

    Just ensure your nozzles are clean and do not have remnants of material hanging off them which will affect the distances.

    I could not get the calibration print to stick no matter what I did with the z (piece of paper under the nozzle) I tried with slight pressure, I tried with quiet a grab on the paper, got no improvement.. 

     

     

    Presume your talking about the 'normal' UM setup here to ensure bed is level etc??

     

    Have you then gone into the 'dual head' area under maintenance and set the Z values in there? (can't confirm the name at the moment as printer running, but it's section for Mark2 upgrade!).

     

    Go to the bottom of the available options there until you see Z adjustment, and adjust head 1 until the nozzle just touches the glass bed (you can sometimes hear a change of tone from the stepper motor when it touches) then save.

     

    Go back up to change extruder head, and select head 2 - back down to Z adjustment and do the same as above - you should then be good to go. Just change extruder head back to 1 before leaving the dual  head options unless you want to do a print using the second head - cura output when using standard single head will work with head 2 fine, as long as head 2 is mounted first before starting the print 👍

    Probably a custom configuration file (as it's not shipped in Cura)? It might be that the version number in that file needs to be updated then.

    Have had a look in the files from the Mark2 and think I have found the error and now working fine for me ?

    hardware_type = nozzle was missing under the 'metadata' section in the config file for each nozzle size.

    correct please definition of nozzles for Сura 3.4
    [values]
    machine_nozzle_size = 0.6
    machine_nozzle_tip_outer_diameter = 1.25
    coasting_volume = 1.36
    speed_wall = = round (speed_print * 4/3, 1)
    speed_wall_0 = = 1 if speed_wall <10 else (speed_wall - 10)
    speed_topbottom = = round (speed_print / 2, 1)

       then what is highlighted should be removed .... I have to Cura 3.4 works.

    Changed this on all 4 sizes and now no error message and nozzle size now shows when using Mk2 - Many thanks indeed ?

    Hi guys,

    I am trying to add a new material profile for PETG, but after filling out 2-3 fields the software cancels the adding of a new profile and selects the ABS profile at the top of the list.

    I have tried duplicating and creating, both same result. I have added material profiles before without a problem, but now it is not playing ball.

    I have the latest update, restarted PC, everything I can think of.

    Any assistance would be greatly appreciated, thank you.

     

    You don't state which machine your using, but had similar problems with my UM2 whilst trying to add PVA - looks like Ultimaker do not allow any 'materials' they think your machine can not run ?

    Have a look at this thread - I found a way around this problem ?
