  1. I'm not sure what exactly the question is... Newer printer models from Ultimaker or in general? UM3 and S5 are using gcode flavor "Griffin", it is very unlikely that this will be back-ported to older machines. But the differences to "Marlin" are marginal (a special header section and one or two custom gcodes). My recommendation is to use a recent Cura version with "Marlin" for UM2. Do you have concerns?
  2. Don't forget that the whole idea dates back to 2013 or even earlier. Slicers didn't had so many advanced settings in the good old days and "Ultigcode" was an enhancement on top of the normal behavior of Marlin. In theory you can use the same gcode file for different types of material. Temperature, retraction settings and flow rate are handled according to the material settings on the machine. It was a pretty smart idea back then but the concept is a bit outdated, because slicing software is much more advanced nowadays (feature wise). There's a reason why Ultimaker itself doesn't use it anymore on more recent printer models. Yes, no problem - that's a good way to test things out. No, why do expect a problem? Besides the fact that Cura can be used to send firmware binaries to the printer, those two things are pretty unrelated to each other. You can use pretty much any available firmware version on the printer and feed it with gcode from pretty much any software that "speaks" Marlin. BTW: if you start "Marlin" gcode files from the sd-card, the printer will show an "override settings..." message. That's fine, it's just the indicator that the material settings on the printer are not used (which is exactly what you want). Just press "continue".
  3. With gcode flavor "Ultimaker 2" there's only one printing temperature that is used for all layers. ("initial" and "final" are only relevant for multi extrusion projects and don't matter anyway). Well, technically... the post processing script works fine and adds these M117 commands. Unfortunately the UM2 firmware just ignores them. The usual Ultimaker design policy indicates that the user shall not be bothered with superfluous details. 🤷‍♂️ So: no luck with the standard firmware...

    Wenn ich das richtig verstehe, möchtest Du also von Hand das nachbauen, was der "Mosaic Palette" macht? Verschiedene Farben vom Filament zusammensplicen und dann damit bunte Objekte drucken? https://www.mosaicmfg.com/
  5. A Cura project file is a 3mf file and contains the model and the print settings. Your description sounds like you want to load only the model, but not the settings from the file. This behavior can be changed in the "Preferences" dialog.
  6. There we have it! A ride-on lawnmower with RGB lights - makes sense! (and it don't even needs a lawn to look good) And let's hope that there's an option to switch the lights off at night... this time... 😝
  7. You used the wrong username, that's all. Follow point 2 of the instructions more careful: https://community.ultimaker.com/topic/15804-how-to-set-ip-address-without-wifi-or-dhcp/?do=findComment&comment=215658
  8. I don't know what you see... It's obviously nothing more than an Ultimaker with "black chassis option"... finally! 😛
  9. Im Boden vom Druckkopf. Wenn man ihn vorn aufklappt, sollte im Boden eine kleine Platine zu sehen sein. Beim Ultimaker 3 ist sie beschriftet mit "Capacitive Sensor Board" - ich nehme an, das ist beim S5 so ähnlich. In diesem Beitrag sind Bilder vom zerlegten Druckkopf: und hier wurde erklärt, wie die Messung funktioniert:
  10. Arduino devices are very limited on memory, that's why the firmware doesn't sort lists. It just reads the first few visible lines from the sd-card and continues reading only if one rotates the encoder wheel. Such a sort feature would require a more modern microcontroller (with more RAM). It's the same problem as on the first simple mp3 players. On a freshly formatted sd card the order will be almost certainly the same order as the files were put on the card. There are tools for Windows, that are able to subsequently (re-)write the sd card in a sorted order, but i don't know how reliable or trustworthy those are. (search for "FAT sorter" or "SD sorter")
  11. Always first things to check: Take sure that both "Safety"-jumpers are still in place and the 24V source is still there (can be measured at the marked connector). Schematics are on GitHub: https://github.com/Ultimaker/Ultimaker2/tree/master/1091_Main_board_v2.1.1_(x1)
  12. Hi Richard, once upon a time... as the UM3 was launched... a lot about the bed level compensation was explained by the developer(s) itself:
  13. BTW: that's a smart idea. I think, someone should copy this for the Mark2 definition...
  14. There's one more thing to do. The setting "Offset with Extruder" has to be enabled. It's easily accessible with the "Printer Settings"-Plugin, or set the value of "machine_use_extruder_offset_to_offset_coords" in the json file. As mentioned - it's not the originally intended way for Mark2, but may be handy for your ideas someday. And be aware that Cura "automagically" compensates the extruder offset in the preview mode. You'll need a different gcode-viewer to actually check it before printing (CraftWare is quite nice for those things). Here is a screenshot from the Simplify3D gcode viewer - sliced with Cura, extruder offset 18mm (just to prove it 😏)
  15. Well, the extruder x/y offsets in Cura and the ones on the printer will be added together in the end. That means: i would use one of them and set the other one to zero, not both at the same time. The Mark2 printer definition for Cura is made with the intention to use only the extruder offsets on the printer (all offsets are zero in Cura). Or you can probably do it like it is made on the UM3, if it better fits your needs: - remove the disallowed area on the left - configure the main part of the x offset in Cura (18.0mm) - use the offset setting on the printer for fine tuning of the last few fractions of a mm (+-) (no guarantee, but that's how it works on the UM3 - and i hope it does not sound too confusing... 😏) And for single extrusion prints with the main print head: use the normal UM2 printer definition as usual, not the Mark2 one. In general... yes. But take sure that you set proper starting values for the extruder offset on the printer first (if you've changed those). IMHO x = 18.0 and y = -25.0 are the defaults of the firmware. And be aware that the provided calibration gcode is in "Ultimaker" gcode flavor fro 0.4mm nozzles. So take sure that you have configured proper material settings for both extruders on the printer. (you can slice your own gcode with the stl files from GitHub at any time though)
