  1. My file error was changing the fan from 100 to 10.  I now changed it to 010 and the import works fine. 

    I have now followed Ambassador's advice to make a new pre-set.    After importing and exporting I have this file

    [material]
    name=PLA
    temperature=210
    temperature_0.40=210
    temperature_0.25=210
    temperature_0.60=220
    temperature_0.80=210
    temperature_1.00=220
    bed_temperature=60
    fan_speed=100
    flow=100
    diameter=2.85
    [material]
    name=ASA
    temperature=245
    temperature_0.40=250
    temperature_0.25=210
    temperature_0.60=220
    temperature_0.80=210
    temperature_1.00=220
    bed_temperature=85
    fan_speed=010
    flow=100
    diameter=2.85
    [material]

     

    I have imported this.  For some reason the first import failed.  I tried again and now I have the choice of PLA and ASA on the printer.   Yeah!

    Thanks everyone

    It depends... The following applies only if you use Cura and the (default) GCode-flavor:

     

    https://support.ultimaker.com/hc/en-us/articles/360013127919-Custom-material-profiles-for-Ultimaker-2-and-Ultimaker-2-

     

    I followed the instructions to make a new material profile on the SD card.  I then imported the profile as instructed, but when I go to the materials choice on the UM2Go+, only PLA is listed and not my new profile for ASA.   FWIW I am now using the Tinker Marline firmware on the UM2Go+

     

    Any suggestions?

     

     

  3. So I have installed the printed bed.   I have upgraded the software.   I have followed the instruction to change the settings for PLA.

     

    My alternative filament is ASA, that I usually print with the nozzle at 245C and the bed at about 85C

    Can I store these settings in the customized option or do I set them each time I change from PLA to ASA?

     

    So far so good

  4. Just a thought for anyone else upgrading their UM2Go.   I upgraded with the official kit from Ultimaker that takes a U2 to a U2+.  The feeder is meant to go on the left side of the back (when looking from the front), but on the UM2Go its on the right.  This means the the little lever one pulls up to allow filament to pass is irritatingly on the inside edge and not the outer edge.  It might explain why the wires did not need reversing?

    If I were doing this again, I would buy the components separately and choose the feeder for the U3 the is meant to go on the right side of the rear (if it can be bought separately that is).

    Meanwhile I have made a reel holder for the filament reel so that the reel is off the printer.  Now I can get to the feeder easily

    Oops.  Yes.  I think I "pointed" you to an HBK version (which is what I have on my 3 um2gos) without thinking.  If you load the wrong one you won't break anything.  The HBK one will complain that the bed is too hot.  Similarly with the dual extruder firmware - it will complain that extruder 2 is too hot.

    If I buy the heated bed from GR5 Store (is that you??)   would I then change to load the HBK version?

     

    Thanks

  6. OK thanks

     

    Found the Tinkergnome 19.03.1 at https://github.com/TinkerGnome/Ultimaker2Marlin/releases/tag/V19.03.1

     

    I see that there are 4 files for UM2Go.   Obviously I do not have a dual version (who knew that one could?).  What does HBK mean?   I am assuming that I load the plain/non-HBK version

    Tinker-MarlinUltimaker2go-19.03.1.hex

     

    I have Windows 10 laptop.

     

    Any thoughts/advice about custom printer profile in Cura??

     

    Thanks

  7. I am not familiar with how GitHub works and cannot seem to find the place with the firmware for the UM2Go+ with and without a heated bed.  Can you point me in the right direction?

     

    I have followed a link to find the site with files to create a profile for upgraded UM2Go.  https://www.youmagine.com/designs/ultimaker-2go-cura-machine    However the folders referred to for Cura 2 do not seem to relate to Cura 4.6    I do not have a definitions folder, Variants folder, or images folder.   It's not clear to me how I make the UM2Go+ custom profile.   Can you/Labern help a simple surgeon?

     

    Many thanks

  8. If I update the firmware to the tinkerGnome firmware for UM2, will the firmware expect the Bowden tube to be the length of the tube on an U2?  

     

    For now, I can simply use the shorter Bowden tube that came with the U2Go.   Good to know that its not the same at both ends

     

    Thanks

     

    Boyd

  9. If you have three U2Go+ do all have heated beds?  If they do, which one have you fitted?

     

    Do you have a printer profile for Cura of the modified U2Go+?

     

    Finally, I have successfully printed a calibration cube.  One thing I found that when loading the filament, the fast travel got the end only about 1/2 way along the Bowden tube.  If I load tinkerMarlin, can I make it go to the print head as it should?

     

    Many Thanks

  10. Bloody hell!.   I reversed just one pair of the wires.   Now the motor works but in the wrong direction.  When I set it to unload it pulls filament up.   When it tries to feed the new filament, it pushes it out.   

     

    So finally wired the JST back to how it was originally and the motor seems to work correctly.   It spits out filament when unloading and pulls it in when loading.    

     

    So how come I was advised to reverse the motor.  Is there something else I do not know?

  11. Good link.   It says..........................................

     

    To get the motor moving in the right direction, is actually does matter which coil is which and what the polarity of the coils are. However, if they're wrong, the motor just turns the wrong way, it's easy to fix that by swapping wires. Pick one of the following in order to reverse the stepper's direction:

    1. Switching the polarity of either (one) coil, like changing ABCD to BACD or ABCD to ABDC.
    2. Swapping the coils, like changing ABCD to CDAB.

     

    So back to re-do the wiring.  Probably best to invest in a crimping tool

     

    TM

  12. Help!

    I installed the new feeder motor.   I cut off the original JST connector and swapped the outer wires.   I do not have a crimper for JST so used surgical clip to squeeze the crimp

    So the wires were originally Black, Green, Red Blue - shown in photo with connector off the board.    Now they are Blue Green Red Black as shown with connector on the board

     

    When I test with the change material command, the motor does not spin.

    If I connect the original motor JST  it does spin with the remove material step

     

    Can I double check that I have reversed the wires correctly? Of course it could my poor quality crimp but before doing again I wish to know that the order is correct

     

    Thanks

  13. Now back so continuing the upgrade.

    I bought a 22mm hole cutter to make the bigger hole for the stepper motor.  Printed a drill guide to go into the metal backing plate to centre the pilot hole for the hole cutter.  I drilled 4 x 3.5mm holes for the retaining screws that go into the motor and used them to hold the metal backing plate.     Hopeless!   The hole cutter would not stay located even with the pilot hole.

     

    So I used the backing plate as a guide and used a Dremel to cut away to make the 22mm hole.  After some fine tuning, new stepper and new feeder now installed on the back of the U2Go

     

    Now to swap wires.

     

    Do I need new firmware or not?

     

    Thanks

  14. There are 4 wires (2 pairs) to the stepper motor.  Which ones do I swap?

     

    The stepper motor is not bigger, it is the feeder itself.  The feeder is the same as the one on my U2+ and U3 and much beefier than the one that came with the U2Go.  I think I will move the feeder by drilling new holes in the back plate.  No one will see once it's in place.

     

    Thanks

  15. Thanks

     

    1) Can I ask about the wires for the feeder stepper motor.   The upgrade kit comes with a new stepper motor for the feeder.  Since this is designed for the new feeder, do the wires need reversing?   If they do, which wires do I reverse out of the 4?   I have a 4 pin JST male and female so can create a new plug

     

    2) The new feeder is wider than the original.   As a result the mounting plate and the feeder abuts the side panel which stops them lying flat against the back surface.   What is the best way around this?  I cannot put a spacer under the mounting plate as the stepper cog would then not engage with the cog in the feeder.   One option is to cut a way a section of side panel??? However the metal plate would sit over the two screws at the top which would prevent the metal plate lying perfectly flat.   Would this cause wear of the cogs?

    Alternatively I could drill new holes to move the feeder 6mm towards the middle and down to avoid the back plate screws??

     

    Thanks

  16. Thanks

     

    I suspect this is a dumb question but what would happen if you created the Gcode with the U2 profile in Cura and then used the gcode on the U2Go?

     

    I have a friend with a laser cutter.    Any chance you can share the dxf for the front door?

  17. I have an U3 and a U2+ and am used to creating and changing material profiles within Cura

    I have now bought an Ultimaker2Go.   I have launched Cura and chosen U2Go as my printer.   When I try to change the material settings they are all grey out and cannot be changed.

    Help!   Surely I do not have to accept the default settings?

     

    Thanks

  18. I now have the Ultimaker 2 Go and now am starting the mods.

     

    On my Ultimaker 2+ and the Ultimaker 3 I have BuildTak Flexible plate system which I love.   I have given up with the BuildTak sheet but find it ever so useful to pull the FlexPlate out the printer to then remove the print rather than doing this with the confines of the printer.   With the new baby printer, it would be even more of a help

    Any reason not to use the Flexible Plate with the U2Go????  BuildTak do not make a plate small enough and are quite costly, so I will try Zimple instead

     

    Next I am looking to buy a heated bed kit.    gr5 store looks like it only ships to USA and not to the UK.  However I emailed them and "George" says that he will ship to London. 

     

    On my U2+ and U3, I have front enclosures.   Has anyone made one for the U2Go to save me creating one from scratch? 

     

    Just doing my first print.  Its a PITA not having a heated bed as I have had to use a bit glue to get the filament to stick! I printed a test from the SD card that came with the printer and it looks incomplete.     Have now gone to Cura to make a test print from scratch.   Unlike for U2+ and U3 I cannot create a material profile and I cannot change the default settings.   What is the cure for this????

     

    Finally I realise that the printer came with 1.75mm thickness filament.   I have just swapped to 2.85 and the feeder is not happy.  Is it meant to use 1.75 with this feeder?

     

     

     

    Thanks
