Second Extruder

[printerfan 5]

How do I set my second extruder to be the nozzle I wish to print from in Cura?

 

[Dim3nsioneer 479]

By adding a 'T1' in the gcode before the heating command (and replacing any 'T0' you can find by 'T1')... there is no other way so far in Cura atm.

I know with code you have to be very specific in regards to line placement and spacing.

Do you have a screen shot of how its supposed to look when I type it?

Also, in my gcode tab, there are several segments to select, which one do I choose?

start.gcode

end.gcode

preSwitchExtruder.gcode

postSwitchExtruder.gcode

start2.gcode

end2.gcode

Look at the gcode in each of those, T1 and T0 are only listed in the gcode for start2.gcode and end2.gcode.

This is the gcode in start2code

;Sliced at: {day} {date} {time}

;Basic settings: Layer height: {layer_height} Walls: {wall_thickness} Fill: {fill_density}

;Print time: {print_time}

;Filament used: {filament_amount}m {filament_weight}g

;Filament cost: {filament_cost}

;M190 S{print_bed_temperature} ;Uncomment to add your own bed temperature line

;M104 S{print_temperature} ;Uncomment to add your own temperature line

;M109 T1 S{print_temperature2} ;Uncomment to add your own temperature line

;M109 T0 S{print_temperature} ;Uncomment to add your own temperature line

G21 ;metric values

G90 ;absolute positioning

M107 ;start with the fan off

G28 X0 Y0 ;move X/Y to min endstops

G28 Z0 ;move Z to min endstops

G1 Z15.0 F{travel_speed} ;move the platform down 15mm

T1 ;Switch to the 2nd extruder

G92 E0 ;zero the extruded length

G1 F200 E10 ;extrude 10mm of feed stock

G92 E0 ;zero the extruded length again

G1 F200 E-{retraction_dual_amount}

T0 ;Switch to the first extruder

G92 E0 ;zero the extruded length

G1 F200 E10 ;extrude 10mm of feed stock

G92 E0 ;zero the extruded length again

G1 F{travel_speed}

;Put printing message on LCD screen

M117 Printing...

start2/end2.gcode are used for dual prints only. You have to add the 'T1's in start.gcode and end.gcode on the M109 and M104 commands.

Personally, I wrote myself a plugin for this...

 

[drayson 74]

Would you mind to share this plugin? I guess, there are a few other peaple with dual heads interested in...

It would be awesome to have a plug in with a GUI that easily allowed us dual extruder people to use their second nozzle as the primary nozzle. I second drayson's request, would you be willing to share the plug-in?

 

[Dim3nsioneer 479]

The people at Ultimaker are usually bribed with cookies... well, I also like cookies...

Please give me some days to get it online with a proper documentation...

edit: Actually, I should do some blackmailing as I still need some testers for the new TweakAtZ version...

 

[printerfan 5]

Excellent, thank you so much!

Here you go:

https://github.com/Dim3nsioneer/Cura-Plugins/raw/released/SelectExtruder.py

Documentation on the Wiki pages is not possible atm as they seem to be broken (again). Please report issues on Github.

edit: I was told by Daid that the Wiki pages are read-only atm until a new plugin repository is set up at Youmagine. Thus, I decided to start some documentation on the https://github.com/Dim3nsioneer/Cura-Plugins/wiki.

 

[printerfan 5]

Thank you for sharing. However, I'm not a programmer, so I have no clue what to do with the information you linked. I assumed the plug-in was downloadable GUI.

Do I copy and paste a section of the code you listed on Github into Cura?

 

[Dim3nsioneer 479]

Just right-click and save the file into the plugin folder of your Cura installation. Then (re) start Cura and enjoy the plugin.

[drayson 74]

Tried it yesterday and it works - thank you for sharing!!

[printerfan 5]

I tried installing the plug-in, but when I opened the 14.09 folder, there was no additional folder for plug-ins. There where only 3 files in the 14.09 folder "current_profile", "mru_filelist", and "preferences". I saved the plug-in file in the 14.09 file as a .txt.

Did I install the plug-in correctly?

 

[Dim3nsioneer 479]

Not yet...

The plugins have to be installed in the 'plugins' subfolder of the Cura installation path, not the user settings path. On Windows the installation path is something like 'C:Program files (x86)Cura_1x.xx' and the user settings path something like 'c:usersYourUserName.cura'

 

[printerfan 5]

Okay, looks like I have the plug-in installed now. Thank you for your help, I will let you know how it works when I get a chance to test it.
