  1. Hi @BarraVox,

     

    Great improvement.

    Sure there is, @GregValiant have made a plugin that can adjust the fan at the line level you want.

    I'm not sure if this plugin work with the newest Cura versions, but he'll answer.

    Just checked and sure it works with all of the latest..  (OFC 😉)

    You find it at the "Marked Place in Cura", named: "Advanced Cooling Fan Control".

  2. Just looked at the plaque in S3D and sure the problem are the shadowing visible in layer 20.

    If you change the the color scheme from "line" to "layer thickness" it's more easy to see this shadowing in the gcode file, using Cura.

    So then I'll see that your solution make sense as there in no under laying "disturbing" layer present..

     

  3. Sorry man.

     

    Actually, the first thing I noticed on your model was the undercut of the "logo" started inside the infill.

    In layer 20 you'll also see the "shadow" of the logo with the text.

    There are just one layer to cover the outer surface. Then my question, do you have the original cad drawing of this object?

    I'll think this shadow layer disturb Cura/printer in some way visible in the print?

    As have not printed this plaque, I've no idea of how it looks like.

    I'll have a look at the gcode file in S3D.

  4. Aha., Ok. Just to come to think about the setting "Horizontal Expansion", can be found under "Walls".

    Press "search" and use "Horizontal Expansion" then select "Walls", default value here are "0".

    By adjusting this value slightly under "0", -say -0.1 and see if the text become better (not leaving openings).

    This is a way to adjust the width of the letters that might help..

    Note: Using Cura 5.71

  5. Hi @Deses,

     

    Ok, there are lots of way to do this for sure.

    Using "Ironing" may need some fine tuning, I've learned in here - this are the balancing between speed and flow and both have to be with quite a lo settings. Only way to solve this are try to fine tune the setting for your printer, maybe someone have a profile for your printer printing nice using Ironing?

    Hmm., maybe @GregValiant have some good advice with this?

     

     

  6. Hi @Deses,

     

    We would normally select the highest height Z resolution as possible, with your printer 0.12 mm, then your model will be 38 layer height. This will give 5 layers for the symbol and the letters to be extruded.

    You'll need to lower the speed to default top layer speed 25 mm/s (or maybe less!).

    To make a smooth surface (top), select "Enable Ironing" under "Top/Bottom" in Cura, but remember to deselect the "Iron Only Higher Layer" box setting. This way both the plaque surface and the text plus symbol are ironed.

    In order to save filament and time, we're using to sink the model into the bed in order to print only the interesting layers.

    Just use a negative value for Z height.

    But a smaller model with same text symbol type go much faster for sure.

     

    Just some small tip.

    Good Luck

  7. Hi there

     

    When we talk about this matter, it can be tempting to mention the "competition" among manufacturers of 3d printers as to who has the printer that prints the fastest with good quality. So, how fast can a 3d printer with 1.75 mm filament print? Here, of course, the selected nozzle size plays a role, as you can actually print much faster with a larger nozzle and still have good quality and accuracy on the model. With this in mind, I'm not so sure that 1.75mm size filament will displace 2.85mm type filament, -but rather the opposite may happen (IMHO). But time will tell.

     

    An UltiMaker printer can print at a "fairly" high speed with a 0.6 mm or 0.8 mm nozzle.

     

    Thanks

    Torgeir.

  8. Hi @BarraVox,

     

    to be honest, I cant see that any support starting mid air.

    I'll see you're using tree support "everywhere", and as far as I'll see -this all is good..

     

    However, we do not know what printer you're using, -but you're using Cura 5.71

     

    Here's the overview picture of your gcode file.

  9. Hi @LePaul,

     

    Just saw your posting and the link to github.

    According to the temperature "map" during heating up the bed and the nozzle -it appear to be a power dump just when the printing started. This is "kind of known", when the power supply deliver close to max output.

    May happen, when we're starting printing using high power over an extended period (warm up to high temp) -and when all the steppers motors suddenly are starting.

    A general advice here will be to make sure the main PCB have forced (fan) cooling and that the power supply also are at some cooled location..

     

    My best assumption at this stage.

     

    Thanks

  10. Hi @canaksaya,

     

    The no 2 extruder port "has" to be activated as the "primary port" in the firmware.

    The "firmware" is the program that's control the microprocessor on UM2's main PCB.

    Modifying the firmware might be the bets way to go, I'll think.

     

    Some third party "firmware's" may be used as well..

    Someone else might chime in here. 🙂

     

    In the meantime, I'll dig a little into this matter.

     

    Thanks

  11. Hi @Andrew_F,

     

    To answer this simple, -there is an open (rupture) in your temperature wiring!

    When this happen, the the temperature go sky high..

     

    "How high, depend of the internal circuit after the "PT100" input!"

     

    So, there is a broken wire, some place between your nozzle and the feeder!

     

    This is where the wiring bundle always move/bending, -just look here.

     

    If this was a permanent failure, it would fail all the time, but this is intermittent -so a now and then connection..

     

    The wires always on a move, -suffer the most, -go figure.

     

    Thanks

  12. Hi @Nils_007,

     

    This is very strange. It looks like the nozzle bed height is way to high, when looking at the "brim layer".

    Are your printer modified in any way?

     

    Here is a link to Eirin in "fbcr8", she made this -how to remove an clean the UM2+ feeder type:

    https://support.fbrc8.com/hc/en-us/articles/115003853603-Reassembling-the-Ultimaker-2-Ultimaker-3-Feeder

     

    Here are Troubleshooting and Advice as well:

    https://support.fbrc8.com/hc/en-us/categories/200330744-Troubleshooting-and-Advice

     

    I've used standard setting in Cura 5.70 and saved it as a project and from this file you can save the gcode file into your sd card for your UM2E+. Here it is: UM2E_Plus_3DBenchy.3mf

    However, for UM2E+ I'm using Cura version 4.13.1 (the latest version of Cura using the old slicing engine).

     

    Thanks

  13. Hi @Adventurehill1,

     

    This answer quite a few thing.

    The versions of Cura before ver. 5.60 had some weird issue just with the support on certain places, but not on all print objects. This might also occurs differently caused by "some" model / profiles..

    When come to the version 5.60, I've had some issues with it, -but with the new arachne version all (I've seen) this is gone.

     

    I'll think this version; Cura 5.70 are the best version I've seen from Cura.

     

    I wanted to see you printing the cube with "Z" up -just alone without any support, just to avoid the stringing from the support. This way, you may isolate problems one by one -I'd like to think..

     

    I'll think you're right in assuming there is no under extrution.

    The E-step are calibrated numbers / mm you confirmed.

     

    Did you ever print with PLA with success or.(?)

    This will be kind of indication that your firmware are working OK.

     

    Thanks

  14. Well, -It's the support that's destroy your model in the first place.

    Rotate your model so the "Z" is pointing straight up, the turn off the support -then you will have a much better model to analyse, for the one trying to help you and for yourself.

     

    Are you sure you're using a 0.4 mm size nozzle? Or, could it be a much to high feed rate setting in your firmware?

    I'll ask this as the line width setting in this last model was 0.24 mm (for a 0.4 mm nozzle) Cura warn you here with "Min layer width 0.34 mm). Still your model looks like this.(?)

     

    You're using Cura 5.6.0 , Anycubic advice using Cura 5.2.0 as the profiles are made with this version, I would jump to Cura 5.7.0!

     

    Maybe you tell us a little bit more about your printer.

     

    Thanks
