Den Offset hast du richtig eingestellt? Bei mir in Y. Normalansicht. Layeransicht um 26mm nach hinten versetzt.

Habe ich hier gepostet: http://umforum.ultimaker.com/index.php?/topic/3129-dual-extruder-only-one-object-print-on-the-second-nozzle/ Für die 2. Düse, folgendes oben in den "start.gcode": M109 T1 S{print_temperature2} T1

Oh man, it´s so easy. M140 S{print_bed_temperature} M190 S{print_bed_temperature} M109 T1 S{print_temperature2} T1 Thank you very much.

Thanks, but I'm only an user not a programmer.

I have added in my start.gcode: M140 S{print_bed_temperature} M190 S{print_bed_temperature} M104 T1 S{print_temperature2} M109 T1 S{print_temperature2} The temperature of the 2nd nozzle is ok, but the 2nd extruder don't move.

Hi Sander, yes, i want to set the '2nd' Nozzle as the first one.

Hi Daid, is it possible to print just one object on the specified nozzle? I have different colors, and I want to print the one defined color. What can I do to not to change the filament. Thank you.

That's it. It works fine now . Thank very much.

@Daid I set this at the top of the start.gcode. M140 S{print_bed_temperature} M190 S{print_bed_temperature} M104 T0 S{print_temperature} M104 T1 S{print_temperature} M109 T0 S{print_temperature} M109 T1 S{print_temperature} In cura are two different temp´s of the nozzles. But cura set all temp´s at T0. :( What´s wrong with the start.gcode?

@Daid Thank you very much for setting it in the start.gcode. It works with one nozzle, but not with the second nozzle. Until now, I always changed the sequence of the Mxxx in gcode, but it would be better to set it in cure before. e.g. from: M140 S50.000000 M104 T1 S210.000000 M109 T0 S215.000000 M109 T1 S210.000000 T0 M190 S50.000000 to: M140 S90.000000 M190 S90.000000 T0 T1 M104 T1 S200.000000 M104 T0 S235.000000 M109 T1 S200.000000 M109 T0 S235.000000 Works very fine, because the two nozzles are heating at the same time, after bedheating. @gr5 Thank you for the link.

Hi Daid, is it possible to change the preheating from first nozzle to first heatbed in cura? While the time for heating the nozzle is about 2 minutes and the time for the heatbed is about 10 minutes and in that time the filament is melting away. Regards Thomas

Very good job. The wall on the side is a good idea, but you have right, it should be an option in cura. I will try the wall next time.

That sounds very good. Thank you.

Hi gr5, thanks for the link. I currently have these settings. // default settings #define DEFAULT_AXIS_STEPS_PER_UNIT {78.7402,78.7402,200.0*8/3,760.0*1.1} // default steps per unit for ultimaker #define DEFAULT_MAX_FEEDRATE {500, 500, 30, 30} // (mm/sec) #define DEFAULT_MAX_ACCELERATION {9000,9000,600,10000} // X, Y, Z, E maximum start speed for accelerated moves. E default values are good for skeinforge 40+, for older versions raise them a lot. #define DEFAULT_ACCELERATION 3000 // X, Y, Z and E max acceleration in mm/s^2 for printing moves #define DEFAULT_RETRACT_ACCELERATION 3000 // X, Y, Z and E max acceleration in mm/s^2 for r retracts I will reduce the acceleration times. I will soon replace the LM6UU with brass bearings. greeting Thomas

Hi Daid. Thanks for the new version of Cura. Is there a way to change the fill under the sloping walls with zigzag because the drives are heavily burdened. In Kisslicer it's the same. The guides on the print head are already loose with at least 0.1 mm. greeting Thomas
