  1. It's a Cura setting: open the machine settings in Cura go to "G-code flavor" and select "Marlin" from the list re-slice done
  2. Replacement patterns from these legacy Cura versions do not work anymore (AFAIK). Be aware that this thread is nearly 5 years old... Here is an example (extruder temperatures) for more recent Cura versions:
  3. There should be a setting named "Brim only on outside" - which is probably enabled by default. I would disable it and check if it makes a difference. (make the setting visible first or use the search function)
  4. What kind of printer is this and which version of Cura is used? (and because it's not mentioned: are we even talking about Cura...?) Be aware that M140 does not wait until the temperature is reached, only M190 does. In addition: {print_bed_temperature} is deprecated (for quite some years now) and not a valid variable name for Cura anymore, the line will probably be ignored by the firmware. It should be closer to your intention when you swap the sequence to: M117 Heating up PEI Plate M190 S80 ; wait until 80C are reached M140 S{material_bed_temperature_layer_0} ; set to temperature from Cura - but do not wait Your approach from the first post should work too if you correct the variable name.
  5. The technical reason is easy: The Mark2 definition inherits from the regular Ultimaker2 plus definition - and Ultimaker has a whole bunch of materials excluded for the latter. See: https://github.com/Ultimaker/Cura/blob/master/resources/definitions/ultimaker2_plus.def.json#L16 If you want to experiment - copy the marked line from the Ultimaker2 to the "Mark2"- json-file and define your own list. Essentially: overwrite the list with a shorter (or even empty?) list.
  6. I'm not aware of an easy way to switch between different start scripts in the printer definition. I would add two separate printers to Cura - one for single extrusion prints and another one for dual prints.
  7. There should be a checkbox with the label "Enabled" somewhere... I use the "Sidebar plugin" - so it may be in a different position than in my screenshot - but it is there. If only one extruder is enabled (or present), Cura no longer adds tool change commands to the gcode and the pre-selected tool should just stay active. Personally I don't use Cura for single extrusion prints, but that's what i understood from the posts above? 🤷‍♂️
  8. Marlin 1.1.x is very different compared to the older versions that are used as the basis for Ultimaker firmware(s). So i can only guess. "WATCH_BED_TEMP_PERIOD" has something to do with thermal protection, right? "Paused to use" is not to be found in Marlin sources. But there is "busy: paused for user" - which is a normal "keep alive" message that is sent to the printing host while the printer is performing long-lasting operations. It's possible to (temporarily) disable "THERMAL_PROTECTION_BED" during the testing period. Just to rule out configuration errors in this area. But don't let it run unattended.
  9. Just to be sure - you have disabled Extruder 1 in Cura? And don't forget the other details of @navigators method:
  10. "Extruder Start G-code" is the wrong place. Just increase the size of the "Machine Settings" dialog and click inside of the script frame(s). The script content will "magically" appear by doing this. It's one of several "Cura glitches" IMHO 🤷‍♂️ vs.
  11. Your pictures do not look like the printer definition of an Ultimaker 2+. It looks more like a Mark2, but with an incorrect start script. Was this per mistake or is it somehow intended? I would add an "Ultimaker 2 Extended+" afresh to have a good starting point again. Or - if the printer is indeed a Mark2 conversion: you could add a new "Foehnsturm Mark2", adjust the z-height or compare/repair the start script.
  12. well, a missing comma here and there can ruin your day... 🙂 There are validator tools for json-files (https://jsonlint.com/ for example). It's a quick check and can save you hours sometimes. Good luck!
  13. Simply use an overlapping "modifier mesh" and select a different extruder for it. If you don't want to model your own, you can "misuse" the support blocker mesh like shown in this video (just select the other extruder instead of modifying any settings):
  14. Willkommen @Stefan81! Die gcode-Dateien sind zwischen den beiden Druckern nicht austauschbar. Ist in Cura jeweils der richtige Drucker ausgewählt? Beim Start wird von der Firmware der Datei-"Header" ausgewertet (Kommentarzeilen am Anfang der gcode-Datei). Mindestens der Druckertyp, Printcore(s) und Materialauswahl müssen mit der Auswahl in Cura übereinstimmen. Im Zweifel kannst Du eine fragliche (Beispiel-) Datei auch hier hochladen, dann sieht man vielleicht, was damit nicht stimmt.
  15. Standard threads are designed for traditional shape cutting and are quite a challenge for 3D printing in general (because of very steep overhangs that like to curl upwards). I think a small "fudge" factor is a good idea. Plastic threads usually need a bit higher tolerances than metal ones. There's a reason why trapezoidal and buttress threads are preferred for plastic parts. Your prints are looking a bit weird though. Like they are either printed with very thick layers or with activated experimental settings (like "Make overhangs printable"). All assuming that the bolts are printed in upright standing position...? What material is used? Take sure that you print those things with max. 0.1mm layer height (better 0.08), not too fast, with as much cooling (fan) as possible and without any tricks or supports. It's well doable this way - at least for thread diameters of 8mm or more.
