Hi, Somehow it looks like the high of a model is wrong calculated in Cura 4.6x. Can someone please take a look on this too? Maybe I oversee something. I attached a simple project file with a body that should have a hight about 25 mm. Actually I see a hight of 24.75 mm in the G-code file when I select [Use Adaptive Layers]. Deselecting [Use Adaptive Layers] I see the exact hight of 25 mm (=125 layers). Please find attached the project- and gcode file. BugelKunstoff_v461.zip

The plugin Sidebar GUI is maybe what you are looking for.

Sorry for my late answer. I was thinking to find this information in the plugin menu. Something similar to Plugin RawMouse - Show device information window, where I got a little status information when I click a item like Status in your plugin menu. Having this information in the log file is a good point too as this will help when a user forgot about that plugin and ask for help about missing profiles 🙂

Glückwunsch!

This are great news. After deactivating 2093 configurations I had a reduction about 15 sec. Your new addition had removed the corruption of found files. Reverting the changes works too. During the test one thing came in my mind. Maybe it is good to have an status indicator in your plugin that tells an user that it is active. Thanks a lot for your effort. Well done.

Oh no, shame on me: 2020-04-23 10:15:11,421 - INFO - [MainThread] UM.PluginRegistry.loadPlugin [404]: Plugin [SidebarGUIPlugin] has been disabled. Skip loading it. I just check and its working again. It seems I start to forget things these days. Sorry for this question...

Guess, your Plugin is still waiting for approval for 4.6? 🙂

Well, no. I OWN one beside of 5 other self builds. And they are running all with the 4.6 beta and 4.6 from yesterday. Don't start blaming as I also don't do it... Edit: Well maybe I had a bit overreacted after reading the conversation again... I understand your point. Beside this, when you create a new printer profile from your definition files, like an Ender 2 or 3 it looks like the nozzles are available again.

3rd party printers are usually not the responsibility of the Cura development team. How it works is, that you need to ask the owner of this setup or better Creality to support their printer with an working setup profile. Beside this, maybe it is worth to check wether setup a new printer profile helps. This is not a general problem because I had test it just before with creating a new printer profile from the printer definitions and there I have a nozzle size ;). Hope this will help.

Maybe try to reboot your PC. Sometimes the os needs to clean up some installation mess because files get blocked by other processes. Then install once more Cura 4.6. Z-Offset. After installation of this plugin you will find the entries under print settings

Hi, I had the chance to test it with the 4.6 Beta version and faced a little problem in my Cura installation. After deactivating all not needed profiles (2079 configurations) and a new start of Cura I got attached information. Story about this is, that there was 3mf test file that I opened somewhen last year. Later on, I deleted the printer configuration via Cura menu and had not check if all physical files was deleted too. Shit happen... Guess this window isn't driven by your application but maybe there is a better way to delete only this fragments instead asking a user to delete all profiles? E.g. giving a user the option to delete only the profile(s) in question. Loading Cura is a little bit faster 35 instead of 45 sec. I guess, in reality it will be a bit faster (because of this error message) Restoring all profiles works perfect and everything runs like before the change.

Ja, das wird immer gerne in Foren kolportiert. Leider haben die wenigsten davon Ahnung und noch weniger haben jemals wirklich die betreffende Norm gesehen oder gar gelesen. Man darf Litzenenden verlöten. Das ist ausdrücklich nicht verboten. Aber es gibt in der VDE-0100 Verweise, wo man das nicht machen darf wie z.B. dort, wo sich Kabel bewegen oder wo Leistung über solche Kabel laufen. Z.B. steht dort: Dazu gibt es dann noch die Erfahrungswerte, die Entwickler von Elektronik haben. Wenn man gewährleisten muss, das was fehlerfrei funktionieren muss, macht man manche Dinge ebenfalls nicht - auch wenn es nicht verboten ist es zu tun.

Hi @zerspaner_gerd, deine gute Erklärung kann sich bis auf einen Punkt gut nachvollziehen, schön erklärt 🙂 Jagen die UM2 so viel Strom durch den Temperatursensor, dass der anfängt zu schmoren? Spannung und Strom sind hierbei für ein Schmoren eher zu gering. Die Erklärung hierzu ist, dass hier 4 Dinge zusammentreffen, die mit der Zeit immer zu einem Problem führen werden (für sich alleine und schlimmer, wenn sie in Kombination auftreten). Litze hat die Angewohnheit, dem Druck der Klemme mit der Zeit "ausweichen" zu wollen. Hinzu kommt, dass das Mainboard die dumme Angewohnheit hat, sich zu erwärmen, welches dazu führt, dass sich die Litze in der Verklemmung bei jedem Ein- und Ausschalten dehnt und wieder zusammenzieht. Des weiteren erzeugt der Drucker im Betrieb Vibrationen, welche ebenfalls auf die Verklemmung wirken. Letztlich unterliegen Litze und Terminal einem Alterungsprozess (Korrosion), der in Kombination mit den anderen Einflüssen dazu führt, dass sich der Widerstand, wie du richtig angeführt hast, zwischen Terminal und Litze nachteilig für die Messung verändert. Die von dir vorgeschlagenen Aderendhülsen sind ein probates Mittel, um diese Probleme zu lösen (und ganz nebenbei bemerkt, in der Industrie unter diesen Voraussetzungen seit langer Zeit ein Designstandard, der verhindert, dass solche Probleme aufkommen können). So, nun aber genug Kluggeschissen. 🙂

Ups, you are right. Seems that I somehow wasn't focus by reading this or maybe thought that stopping automatic slicing will at least free up some resources Cura need to make this calculations faster.

For the one who start the thread, it is maybe easier to use the first mentioned solution and this is why I put it on first place. By the way, thanks for adding your background information. This should be pinned in a Q&A section for UM2 printers :) For myself I prefer using the second way as I'm using except of one printer only self build printers. I got too often painful experiences from new Cura versions that screw up my profiles what end in a lot of scrap and waste time. Using that way I have more control about my printer profiles and do not need to start from scratch with each version change. (I am thinking for example about these Creality profile disaster in the past or those never ending questions about wrong calculated/estimated print times because of, sorry to say, highly questionable default values for non UM printers.) Beside of this, there are other printers that have this problem too, like Tevo Black Widow, where the first solution will not work. :)

Well, you are using an UM2. It is supposed to use materials that Ultimaker provide with this printer. Anyway there are different solutions/workaround posted in the past in the forum. One is to change the machine flavor to Marlin. An other solution is to modify an existing profile: Add a new UM2 printer profile and rename it to e.g. Ultimaker 2 Copy. Then go to your cura configuration folder: Click in Cura --> Help --> Show Configuration folder. There is a folder called machine_instances. In this folder you will find your machine files. There should be a file named like Ultimaker+2.global.cfg. When there are more than one file with this name check the content of each. There should be one that include in the section [general] the name you have given this printer by renaming the profile (for this example Ultimaker 2 Copy, see below). For the next step please close Cura and then open this file with an editor and add: has_materials = true in the section [metadata]. Here is how the file looks like when you add that line: [general] version = 4 name = Ultimaker 2 Copy id = Ultimaker 2 [metadata] setting_version = 12 group_id = f85b237e-c0b3-410d-b0d7-4b7b44498f89 type = machine has_materials = true [containers] 0 = Ultimaker 2_user 1 = empty_quality_changes 2 = empty_intent 3 = um2_normal 4 = empty_material 5 = empty_variant 6 = Ultimaker 2_settings 7 = ultimaker2 Save the changes and close the file. Then run Cura. You should be now able to select Materials. What does this modification? In the original definition files this option is set to false as UM2 manage materials via firmware. You can find this definition for Windows10 here: c:\Program Files\Ultimaker Cura 4.5\resources\definitions\ ultimaker2.def.json When you are unhappy with the results you only need to delete the printer in Cura and you are fine. -->Preferences -->Printers -->choose the former created printer and hit Remove. Or change the active printer.

Look for plugin Automatic Slicing Toggle from @fieldOfView at Market place. Guess this is what you are looking for.

Dann viel Freude beim drucken.

... und, bist du weitergekommen?

Hallo, ich bin etwas spät mit meiner Antwort. Die Raumtemperatur als Maß zu nehmen ist nicht so gut, da diese auch von der Umgebungstemperatur abhängig ist (usw.). Auch solltest du zur Messung ein Gerät verwenden, dass einigermaßen genau misst. Dafür reicht schon ein günstiges Gerät mit externen Sensor, den du dort befestigst, wo du messen möchtest. Du musst schon am Bett direkt messen und am besten dort, wo auch der Sensor sitzt. Damit kannst du dann zumindest eine Aussage darüber treffen, ob die Werte annähernd passen. Du wirst dann später feststellen, dass auf dem Bett darüber die Werte anders sind und, falls du eine Glasplatte benutzt, diese an der Außenoberfläche ebenfalls geringer sind. Die Größenordnung liegt bei ungefähr 15°C.

Hello @fredkim, unfortunately I don't own this printer. So it is difficultly to me to check your parameters. The only thing I can say is to take care using the same values as in your printer firmware.

Wäre vielleicht eine gute Idee zu erwähnen, von welchem Drucker du sprichst. 🙂 Ansonsten wären die üblichen Verdächtigen ein nicht mehr richtig sitzender oder defekter NTC, deine Temperaturmessmethode, ein defekt im Kabel/Stecker etc.

Hi, installiere dir mal zum Testen die aktuelle Beta parallel zur deiner jetzigen Version. Wenn ich das noch richtig in Erinnerung habe, gab es ein Problem mit dem hin und her schalten zwischen Druckerprofilen bei unterschiedlichen Druckern. Man musste Cura neu starten, wenn man den Drucker in Cura wechselte. Kannst du ja ebenfalls mal testen.

Evtl. beide Drucker gleichzeitig mit dem Rechner via USB verbunden?
