[Ultimaker - Dual Extruder]

ich habe es bei mir probiert, es geht recht gut bis auf den offset vom 2 extruder bei mir fängt er an außerhalb vom bett zu drucken.

jemand da ne idee wie das in dem gcode implementiert werden kann?

 

Den Offset hast du richtig eingestellt?

Bei mir in Y.

Und die 2. Frage geht schneller :smile:

Kann ich in Cura (13.10) meine Düse aussuchen wenn ich ein normales Modell drucke oder muss ich die Farben immer in Düse eins einfädeln und die 2. wird nur im Dualen Modus genutzt ?

 

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

 

[Dual Extruder: Only one Object print on the second Nozzle?]

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.

 

[Dual Extruder: Only one Object print on the second Nozzle?]

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

 

[Dual Extruder: Only one Object print on the second Nozzle?]

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.

 

[Dual Extruder: Only one Object print on the second Nozzle?]

Hi Sander,

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

 

[Dual Extruder: Only one Object print on the second Nozzle?]

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.

 

[Preheating in Cura. First Heatbed, second Nozzle?]

That's it.

It works fine now .

Thank very much.

 

[Preheating in Cura. First Heatbed, second Nozzle?]

@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?

 

[Preheating in Cura. First Heatbed, second Nozzle?]

@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.

 

[Preheating in Cura. First Heatbed, second Nozzle?]

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

 

[Stop oozing]

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.

 

[Looking for beta testers.]

On the update front. I've just made some code which optimizes the small zigzag lines into a smooth line. So no more massive vibration on thin walls. I still need to print with it, but the GCode looks correct.

This should also save some print time and make the print time guess from Cura a bit more accurate (less small moves is less acceleration error)

 

That sounds very good.

Thank you.

 

[Looking for beta testers.]

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

 

[Looking for beta testers.]

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

 

[Throw away your short belts - direct drive.]

Another option is to change the firmware.

#define INVERT_X_DIR false // for Mendel set to false, for Orca set to true, Ulti direkt false

#define INVERT_Y_DIR true // for Mendel set to true, for Orca set to false, Ulti direkt true

#define INVERT_Z_DIR true // for Mendel set to false, for Orca set to true

#define INVERT_E0_DIR false // for direct drive extruder v9 set to true, for geared extruder set to false

#define INVERT_E1_DIR false // for direct drive extruder v9 set to true, for geared extruder set to false

#define INVERT_E2_DIR false // for direct drive extruder v9 set to true, for geared extruder set to false

 

 

[A new "Ultimaker" clone]

But it's all a lot stiffer and more appealing and with heat bed.

Is there something new in Ultimaker except CURA.

 

[Ever wanted a metal Ultimaker ? it's the Zortrax]

I think it's good that there are new ideas.

Then it goes ahead even with Ultimaker.

What is at Ulitimaker with wireless, dual extruders and heat bed as announced a few weeks ago?

 

[Requests for next version]

The thin wall issue is also something I handled in the new update. It was pretty high on the priority list as it's the nr2 reported problem (after speed and memory issues, which are also handled with this update)

I need to make some final tweaks, write some manual texts, and make a nice list of changes. I hope to do so before the end of next week.

 

That sounds very good.

I look forward to the new version.

 

[HOW-TO: Build your own Marlin]

I have found it.

Thank you very much.

ThomsS ,to find your hex file:

1) In the Arduino IDE, menu File/Preferences check "show verbose output during compilation"

2) Build the firmware by clicking on the Verify icon

3) the last line of the console window will show you where is located the Marlin.cpp.hex file, which is what you are looking for)

[HOW-TO: Build your own Marlin]

Yes. Thank you very much.

I have made my firmware and direct uploaded a few days ago in Windows 7.

But where can i find the hex-file, like gr5 wrote?

 

Maybe you could talk a little more about "uploading the hex file".

 

[Looking for beta testers.]

I have just time for testing cura.

BTW

My operating system is Windows7 64bit and i take OctoPrint on raspberryPi to control my UM.

I work also with the very fast Kisslicer.

I have the UM remodeled with direct drive rear left, other fan and heatbed.

It runs a modified Marlin firmware.
