difference entre cura pour UM1 et UM2

Recommended Posts

j'ai lu la doc sur cura

c'est assez etrange, quand tu installes cura pour une UM2, tu n'as pas tout ces parametres de reglage de temperatures (lit, fils, tu ne peux pas choisir ta matiere......) par contre si tu installes cura pour une UM1, ces parametres apparaissent !!!! bizard quand meme


alors quand tu installes cura pour UM1, danss file/ maching setting sur la case gcode flavor, il se met sur Reprap (marlin/sprinter) avec touts les parametres qui vont bien (speed temperature, bed etc)

alors quand tu installes cura pour UM2, dans file/ maching setting sur la case gcode flavor, d'office il se met sur UltiGcod, et la, les 3/4 des parametres qui vont bien (speed temperature, bed etc) disparaissent

Alright, I'm going to help Sylvain here and translate for him :)

He already asked this question in the french section of the forum, but since no one own an Ultimaker 2 there, we could not really help him.

Basically, what he is asking is why when you check "ultimaker 2" as your machine during installation, many settings like temperature or filament diameter disappear? This is due to the gcode flavor being set as UltiGcode for ultimaker 2 and setting it back to Reprap make the settings reappear, but there is probably a good reason for it to be set to ultigcode by default.

So I assumed it's because those settings can be set directly on the machine with the built in controller, but since I only own an original ultimaker, I cannot tell for sure.

How is the temperature set on ultimaker 2? How about the heating print bed?

Yes, the bed temp, extruder temp, and retraction amounts are all set directly on the printer, so that you can change those things on the printer without needing to reslice the STL.

Going into UltiGcode also makes three other changes:

1) Retractions are now simply marked with G10/G11 gcodes, rather than an explicit extruder move. This is so that the printer can override the size and speed of the retractions easily

2) Cura no longer includes start/end gcode - those sequences are now built into the printer firmware.

3) Extrusion amounts in the gcode are now measured in mm³ of plastic extruded, not linear mm of filament fed in. This makes the gcode independent of the precise filament diameter, and allows that to also be set on the printer.

The printer control panel allows you to define materials presets that include the relevant temperatures, diameter, etc, so that you can quickly swap between them.

Pas mieux !

Mais j'y pense, c'est peut-être pas si mal d'avoir fait ainsi sur la seconde machine. On peut certainement mieux comprendre ce qui se passe et réagir plus rapidement. En plus de ne plus bloquer le GCode avec des impératifs propre à UM.

Donc gros + en fait :)

Heu.... Niveau impression 3d, je suis un novice ;)

Par contre, niveau programmation embarqué, et Arduino, c'est pas la même. J'ai quand même été à concevoir ma propre télécommande numérique pour modèle réduit. Donc forcément, j'ai un petit bout de connaissance. J'attends de voir ce que ça va donner quand j'aurais la machine dans les mains et des prints de base qui seront ok.

Déjà, commence à faire quelques modélisations. Sort des stl et test dans Cura. Tu saura vite si tu est dans le vrai ou dans le faux.

    • Ultimaker Cura | a new interface
      We're not only trying to always make Ultimaker Cura better with the usual new features and improvements we build, but we're also trying to make it more pleasant to operate. The interface was the focus for the upcoming release, from which we would already like to present you the first glance.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
