  1. This works like a charm with my UM2EXTENDED+ but I had to add starting and ending script (also explanation is here " Starting script (cura): G21 ;metric values G90 ;absolute positioning M82 ;set extruder to absolute mode M107 ;start with the fan off G28 Z0 ;move Z to bottom endstops G28 X0 Y0 ;move X/Y to endstops G1 X15 Y0 F4000 ;move X/Y to front of printer G1 Z15.0 F9000 ;move the platform to 15mm G92 E0 ;zero the extruded length G1 F200 E10 ;extrude 10 mm of feed stock G92 E0 ;zero the extruded length again G1 Y50 F9000 ;Put printing message on LCD screen M117 Printing... Ending script: M104 S0 ;extruder heater off M140 S0 ;heated bed heater off (if you have it) G91 ;relative positioning G1 E-1 F300 ;retract the filament a bit before lifting the nozzle, to release some of the pressure G1 Z+0.5 E-5 X-20 Y-20 F9000 ;move Z up a bit and retract filament even more G28 X0 Y0 ;move X/Y to min endstops, so the head is out of the way M84 ;steppers off G90 ;absolute positioning ;Version _2.6 of the firmware can abort the print too early if the file ends ;too soon. However if the file hasn't ended yet because there are comments at ;the end of the file, it won't abort yet. Therefore we have to put at least 512 ;bytes at the end of the g-code so that the file is not yet finished by the ;time that the motion planner gets flushed. With firmware version _3.3 this ;should be fixed, so this comment wouldn't be necessary any more. Now we have ;to pad this text to make precisely 512 bytes. Ultimaker 2 Extended+_2020.zip
  2. Also I found explanation about gcode: https://www.simplify3d.com/support/articles/3d-printing-gcode-tutorial/ Interesting explanation necessary for solving this problém.
  3. Once again thanks. I printed according your explanation - spliced two gcode files - and this is really working. In the end if we have to modify codes in notepads I would like to say: "FRIENDLY USER INTERFACE".
  4. Thank you very much, for your comprehensive explanation. So you are explaining that I should open gcode files probably in notepad and I should delete parts of these codes and splice/combine these two files. I have never done that to this time. May be I will try it. But I think this is rather complicated. But interesting is what "G92" this kind of code is doing?
  5. I would like to set print with different settings in diferent layers. For example if I print shape like glass with stem, then bottom part - stem, base should be printed with wall thickness 1,2mm and infill 40% but upper part - bowl i would like to print like "Spiralize outer contour". So there should be convenient setting where in diferent layers (upper layers) should be different setting in comparision with layers bellow. Yes, I would like to use these two diferent settings in different layers in one print. Now I use this hybrid setting if I set bottom layers - (for example bottom layers - 620) and from layer 620 to 1000 there I use setting "Spiralize outer contour". But this print is extremly slow? Another option is print stem and then print upper bowl separately and glue these two parts together.
  6. "Brim only on inside" - I need this option badly now. Because I would like to use "Spiralize Outer Contour" so I cannot prepare model with my CAD. When I import this model and I would like to use "Spiralize Outer Contour", this bottom part isn't printed. But I would like to use this part - brim on inside for gluing parts together
