[Stops Extruding Mid-Print (Tried everything I could think of)]

22 hours ago, classified said:

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".

[Build plate heater does not turn on.]

When file is saved in .gcode, the M140,M190 codes are not generated for the Build plate heater. 

cube4.gcode 2.14 MB · 1 download

 

That's a file for an Ultimaker S5 (with GCode-Flavor "Griffin").

The buildplate temperature is set in the header section (the comments at the beginning of the file). That's all the printer needs to know.

Why do think it's a bug?

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?

 

[Infill in embedded holes]

The "bugs" are probably in the stl file.

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

 

 

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!

 

 

[Extruder calibration hell]

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?

 

[Replacing all leds in UM2]

It's a PWM output between 0-24V - depending on the "Brightness" setting.

The led strips are for 24V (at max. brightness).

 

[Replacing all leds in UM2]

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:

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):

[Ultimaker S5 Bauraum vergrößern]

1 hour ago, RaphaelOst said:

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!

 

[Cura stopped cutting models]

One possible cause is a blocked communication to CuraEngine. There's a firewall permission to set during installation of Cura - don't block it.

 

In any case: take a look at "cura.log" and search for error messages.

 

For the location of the log-file see:

https://github.com/Ultimaker/Cura#logging-issues

[UM2(+) 2.1.1 board / ulticontroller display board help]

I have no idea - but a few questions:

 

- Does it make a difference if the broken part of the encoder is not attached?

- What happened to the black plastic housings of the connectors?

- Are you sure that both flat cables are in the correct orientation on both sides (red marking)?

 

 

 

 

 

[Symbol mit andere Farbe in das Model einfügen]

9 hours ago, DirgDiggler said:

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 🙂

[Changing loading speed using pronterface UM2]

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.

I guess, you are asking for "print head shaft x" and "... y"?

 

[Prime tower blocking area]

On 12/8/2020 at 7:17 PM, r_moeller said:

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.

 

[Ultimaker 2 dual extruder firmware needed]

it depends... on what exactly is broken.

 

One crucial point:
For security reasons Marlin firmware requires at least a connected temperature sensor for each configured heater (doesn't matter if a heater element is actually connected).

[Can't connect to UM2+]

On 12/6/2020 at 5:13 PM, jphermans said:

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.

[Firmware modifications for bondtech and um2+]

8 hours ago, Arwen said:

I know it will want an E-step value of 415, but I don't know how to get that into the machine.

 

That's easy:

• install pronterface (or any other software with a serial console)
• connect via USB cable, COM port depends on your operating system, baudrate is 250000
• use the pronterface console to send two gcode commands to the printer:

  M92 E415  ;set e-steps
  M500      ;save settings

 

more about pronterface:

https://support.th3dstudio.com/hc/en-us/articles/360048171391-Sending-Gcode-Via-Pronterface

 

or - even easier:

• put the two lines from above in a (plain) text file
• save the file on sd-card as "esteps.gcode"
• "print" the file as any other gcode-file

 

Check the Marlin firmware 1.0 documentation for more details about specific gcode commands.

 

The use of a more powerful heater needs perhaps some tweaking of the PID values. I think there is a menu option on the printer to change these values (if needed).

Default values of the UM2+ are here:

That's the opposite of a manifold geometry.

You can load the stl files in Meshmixer (e.g.- like i did above) and it will show all mesh errors in different colors.

 

Why is a manifold mesh important?
