    The attached "Cura 4.3.zip" file contains all the relevant (I think) files from the Monoprice version of Cura.

     

    I think the according "quality" files are missing (at least). It claims to have some machine specific profiles:

    "has_machine_quality": true

     

    The quality files in your attachment are the default (generic) files from Cura - don't overwrite these.

    The same goes for the fdmprinter / fdmextruder files - don't change those, let your definition inherit from the newer files of Cura 4.8.

     

    There's a chance that it has it's own material files too, all generic materials are excluded in the definition. This may be specific to your customized Cura version, but check the materials folder as well (just in case).

     

    If you remove the settings "has_machine_quality" and "exclude_materials" from mp_base.def.json the standard profiles and materials become usable.

     

    Hope that helps!

    Kann mir jemand sagen Warum die Extruder setting nicht übernommen werden ?

     

    ...weil beim UM2+ das Material standardmäßig am Drucker konfiguriert und ausgewählt wird und nicht in Cura.

    Hier steht, wie man das ändern kann und noch ein paar mehr Details:

  3. I bet it's there - but the floor space of your house is only 1x1.5 (mm) - the height is 2.3mm (chimney included) - it seems to be some kind of a tiny house... 🙂

     

    The size is shown in the lower left corner of your screenshot, but it is not readable (i guess the forum software scales large pictures down).

    It should be possible to select the object with CTRL+A - afterwards you can use the scale tool. A scale factor of 2000 or 4000 percent gives it a printable size. 1

     

    While we are at it: there are some overlapping vertices and the normals of some faces are pointing inwards.

    I changed the units to mm and scaled it a bit:

    Meinst du die gelbe Linie links? Das wird die Purge oder Prime Linie sein um die Düse startklar zu machen.

     

    ...und das stammt aus dem Startskript (findest Du in Cura in den "machine settings"). Das kann dort auch geändert werden.

    Es müssten genau genommen zwei Linien sein, die jeweils 180mm lang sind.

     

    Das wird erst beim Speichern der gcode-Datei hinzugefügt und kann deshalb im "Preview" noch nicht sichtbar sein.

     

    Ausschnitt aus dem Creality Startskript (mit Kommentaren):

    G92 E0 ;Reset Extruder
    G1 Z2.0 F3000 ;Move Z Axis up

    Also my hotend is all metal. It's a V5 J-Head hotend.

     

    In this case it's easy - do not print PLA with it. It's not made for PLA.

    Warm PLA sticks like crazy to metal. That's why hotends that are suited for PLA do have this PTFE-inliners (well... most of them).

    Or do some hardware tweaks, especially if it's not a genuine product. A good all-metal hotend is very well polished on the inside (or even coated). That makes it (kind of) usable with PLA, but also much more expensive.

     

    There are some good points in this old topic of the RepRap forum, or ask your favourite search machine for "all-metal hotend PLA".

    Start and End G-Code entries in Machine Settings dialog box show up event though I've deleted them

     

    I'm only guessing, but perhaps the default script is used because the customizable part is empty?

    What happens if you put a single comment line in there instead of an empty script? Does it make a difference?

  7. The "bugs" are probably in the stl file.

    Here are all mesh errors marked with a pin (you can check it with Meshmixer).

     

    image.thumb.png.caf5ffbcd8ac866f0feb708f3e5bf933.png

     

    It seems like there are already "magnets" positioned in each hole. There's the "puck" (with 6 holes) and 6 "magnets" in the file - (overlapping the holes) - 13 distinct shells in sum. So... remove all the extra geometry and it should slice fine with Cura:

     

    Puck_with_magnet_holes.stl

    Good luck!

     

     

  8. The linked thread is referring to an "Ultimaker Original" printer from 2013 (with plywood frame).

    But you use an "UM2+" tag for this question.

     

    So.... let me ask first:  what kind of printer?
     

    Default e-steps value for the genuine UM2+ assembly (feeder and motor) is 369

    Have you modified the printer? Why do you have a need for calibrating?

     

  9. As far as i remember: the leds are 3 strips with short (soldered) connector cables in the corners. All held in place with some (self-) adhesive on the front panel.

    The whole strand came out in one piece on my printer. It's a while since i removed the (broken) strips, but i definitely did not disassembled any panels, that's for sure... 🙂 I just loosened the adhesive and pulled the strip out.

     

    Do you have any pictures?

     

    This picture is borrowed from the assembly manual:

    @tinkergnome - ideas?

     

    Well... the connection to CuraEngine does not work. We already knew that. There are no entries about a specific reason in the log file. 🤷‍♂️

     

    It just repeats this cycle over and over again (note the timestamps):

    Hallo,

     

    ich meinte natürlich den Bauraum mechanisch zu vergrößern. 

    Ich habe auch nicht vor meinen UMS5 zu zerlegen, sondern alle Teile nochmal nachzukaufen und aus diesen einen Großraumdrucker mit ca. 1m x 1m x 1m Bauraum zu bauen. Die Software des Ultimakers will ich auch hier wieder verwenden, jedoch müssen daran einige Veränderungen vorgenommen werden, dass diese dann funktioniert. 

     

    LG Raphael

     

     

    Ich will dich ja ungern bremsen... aber...

     

    Auch wenn ein "reverse engineering" technisch möglich wäre... Soweit ich weiß hat die Firmware für die S-Line Drucker keine Open-Source Lizenz (*).

    Nicht das Du da Probleme bekommst... Kläre die rechtliche Seite besser zuerst mit Ultimaker ab, bevor Du die Firmware für deinen eigenen Drucker verwendest.

     

    Heutzutage ist das u.a. fest mit der Cloud / Digital Factory verknüpft, das ist nicht so simpel und bestimmt auch nicht mehr für solche Modifikationen gedacht (von einer öffentlich verfügbaren Dokumentation ganz zu schweigen...).

     

    (*) ausgenommen ist die Arduino Firmware für den "Motion Controller", dieser Teil basiert auf Marlin und ist Open Source. Das nützt Dir aber für den angedachten Zweck nicht viel.

     

    P.S.: die Alternative vom @zerspaner_gerd finde ich gut!

    Oder muss das ganze schon fertig konstruiert worden sein. Also mit Aussparung für das Symbol?

     

    Das wäre in der Tat der korrekte Weg.

    Wenn zwei Geometrien sich überlappen - welche davon soll dann bevorzugt werden? Wie wählst Du das aus? Für das überlappende Volumen sind ja nun beide Extruder zuständig...

     

    Cura entfernt standardmäßig die Überschneidungen und druckt jede Lage abwechselnd. Das kann mit den beiden Einstellungen aus dem Screenshot unten beeinflusst werden. Aber Du hast trotzdem keine direkte Kontrolle, welcher Teil entfernt wird. Da musst Du experimentieren und wahrscheinlich spielt die Reihenfolge ein Rolle, in der beide Teil-Dateien  geladen werden. Besser ist aber... siehe oben 🙂

    What is the command to send to ultimaker  2 via pronterface to change the material loading speed to 50mm/s.

     

    If you're talking about the "change material" menu:

    It's not a setting that is adjustable by gcode commands. You have to customize the firmware if you want to change this.

    Just while writing I have checked with a built in profile which has Brim as standard Build Plate Adhesion Type and found that the area is small with Brim but gets huge by just switching to Skirt. That don't make much sense to me.

     

    That's how i understand it:

    "Prime Tower Brim" is a separate setting (try the search function).

    It will be disabled (by default), if the adhesion type is already set to "Brim". That means: for the default profiles it is only enabled if the adhesion type is different from "Brim". So - simply disable "prime tower brim" explicitly if you don't need it.

    Yeah, even under windows I don't see in the devices the port when connecting the usb.

    When I switch off the printer I see a "unrecognized device" and switching on then it disappears.

     

    The arduino drivers are responsible to create the (virtual) COM port. If this does not work, there's no point to proceed with different Cura versions or any other software.

     

    Are you absolute certain that there's a genuine Ultimaker board in this printer? (most "clones" need different drivers)

     

    The Arduino forum advocates against USB 3 ports and cables, that's perhaps worth a try? The USB-cable that came with the printer would be my first choice.
