  1. Sorry to hear.

     

    I have the Bondtech QR's fitted so don't use the existing stepper motors so unsure how they perform.

     

    I would suggest you log back in via Putty and load up the later firmware json file,

     

    (3.7 – 4.2.5, vi/usr/share/griffin/griffin/machines/um3.json) as I seem to remember that is the latest version (Currently printing so can't confirm but you could just drill down the menus if you know how to in cmd to double check - Then open the file, scroll down and confirm the estep value).

     

    Are you getting the same extrusion issues on both feeders?

    I thought I'd post another update as I've worked through a few issues specific to my use cases. 

     

    I've been doing lots of ABS prints in a hot enclosure (70C+), and it seems like my magnets are getting weaker,  losing alignment or I don't know what. I was never able to reach the furthest corners without the head popping off but it got worse and worse. 

     

    I modified the head and the coupling to include an additional 4 magnets and printed everything over 11 hours with a 0.25mm nozzle in ABS (fusion+ from Innofil/BASF, it's pretty good!).

     

    I also beefed up the coupling to also act as a spacer for the head assembly. What I was finding was that the original design Z height of the coupling was dependant on the top height of the plastic part of the head. And this varied depending on how tight the screws were etc. My modification (which is pig ugly) is captured in the metal part of the head assembly and so is more accurately set over time.

     

    It is rock solid now, I think my magnets were crappy but now I've got 7 of them I think there is a nice safety factor. 

     

    Also just found a great trick using "terrain to STL" and switching the shell extruder to a different colour for contour lines. 

     

    One quick question for tinkergnome, why is it that you've set the maximum temp adjust to be + or - 25 in the Mark2 firmware but not in your normal UM2 firmware? Thanks again for the epic work everyone, I could never go back to a single extruder now.

    Hi @Whom,

     

    Any chance you could share the modified head and coupling files?

     

    Many thanks,

     

  3. Hi @ahoeben,

     

    Great work on the plugin.

     

    Quick question ref smart plug implementation - When clinking 'Print' in Cura, will the plugin look for an instance of Octoprint and if not found, look for an instance of the smart plug and make sure this is on/send a command to turn on and wait for Octo to boot up? Or are you relying on the smart plug plugin for all the commands and as such Octo needs to be running?

     

    I ask as my Pi is powered off the UM board using the same powerlead so whilst the power off function should work well (To turn the permanently on cooling fan off), wondering if it will work the other way.

     

    Many thanks,

    For the second bowden tube, are we supposed to use a standard length or a longer one? Current one has a nice smooth curve to it, it's only a problem when trying to move to the right rear corner of the printer and the second head pops off. Perhaps the magnets I got aren't strong enough. 

    I struggled to get the head to stay in place, whatever length of tube I used, when the feeder was fitted up high, even with the adjustable mount. Once I fitted the feeder lower (To mirror the stock feeder), all worked fine.

  5. Any way of stopping Cura from inserting M141 into the gcode? Pops up as an error in Duet everytime a print is started (More annoying than anything else).

     

    EDIT - Ignore me - just found it in Cura under build volume temp (I was searching for 'chamber') - setting to 0 removes it from gcode

  6. Yes it works but you need to change the text in the .cfg files that you put in the variant folder.

     

    This is for the 0.4mm nozzle:

    [general]
    name = 0.4 mm
    version = 4
    definition = Mark2_for_Ultimaker2
    [metadata]
    setting_version = 6
    type = variant
    hardware_type = nozzle
    [values]
    machine_nozzle_size = 0.4
    machine_nozzle_tip_outer_diameter = 1.05
    speed_wall = =round(speed_print / 1.25, 1)
    speed_wall_0 = =max(speed_wall - 10, 1)
    speed_topbottom = =round(speed_print / 2.25, 1)
    


    and you can find the other details you need to copy from the Ultimaker 2+ files in the same folder for the relevant size nozzles. No need to reset, just close, change and relaunch.

  7. Jumping in on this post slightly but also experiencing a similar issue to above and after a bit of help - I'm struggling to understand how the various fan/cooling settings are linked and which takes priority. So...

    • Under material profiles, printer settings you can set fan speed to a % value.
    • Main side bar, under Cooling - You can enable fan cooling and fan speed again, which is also a % value.
    • ChangeatZ plugin, fan speed is labelled as a PWM value (0-255).

    I'm trying to print with ASA filament but I'm struggling with it atm so if I try a test print, changing the temp and fan speeds, how should I have Cura set up?

     

    Material Profiles - 10%.

    Cooling enabled and fan speed matches profile so 10% Max (2% Reg).

     

    However, with these settings the fans don't spin - Is there a minimum % I need to enter?

     

    Then if I do use the ChangeatZ plugin, how will the values I enter here effect the % settings?

     

    Running tinker on a 2+.

     

    Many thanks,
