    Any tips for avoiding these ugly strings on the wings? :)

    in Coffee corner

    Posted

    Usually as a rule of thumb I use these ratios for PLA (different brands may vary)

    0.1 | 25mm/s | 195ºC

    0.1 | 50mm/s | 210ºC

    0.1 | 80mm/s | 235ºC

    If you see some of this stringing occur during the print, in the tune menu you can tweak the settings (increase or decrease temperature) until it disappears.

    Eventually you'll develop a pretty good feel for this right away :)

     

    Ow that I didn't knew... I never changed the temperature for my PLA, I always sticked to the 210°/60° default settings... When I use 0.06 and 25mm/s should I go lower than the 195°C you're indicating?

    Should I save my slicing in reprap or Gcode? Cause when I use Gcode then I have to make the temperature changes on the ultimaker itself and not in Cura?

    Did you change anything in the retraction settings on the printer?

     

    Hey Didier,

    I made some small changes to the retraction settings.

    The default settings are :

    Minimum travel : 1.5mm

    Enable Combing : all

    Minimal extrusion before extracting : 0.02mm

    Z hop when extracting : 0mm

    These are my settings :

    Minimum travel : 1mm

    Enable combing : all

    Minimal extrusion : 0,01

    Z hop when retracting (mm): 0,0

    I made these small changes after reading this article : http://www.extrudable.me/2013/12/17/highqualityultimaker2/ (check his pics, he made some really nice prints...)

    Any good changes or should I go back to the default settings?

    I'll change my travel speed to 250mm/s and I already got rid of the blue tape. ;)

    Hellow all,

    I tried to print this model : http://www.thingiverse.com/thing:246198 in PLA (210°/60°)

    But as you can see on the pics below, the result is not what I expected. Ugly strings on the wings :p

    These were my settings :

    layer height 0,06

    shell thickness 1,2

    retraction : yes

    retraction settings :

    - minimum travel : 1mm

    - enable combing : all

    - minimal extrusion : 0,01

    - Z hop when retracting (mm): 0,0

    bottom/top thickness: 0,6

    fill density: 15%

    print speed: 25 mm/s

    support type: none

    platform adhesion type: brim (30 lines)

    initial layer thickness: 0,3

    travel speed 200mm/s

    bottom layer speed 15mm/s

    all the other speeds are on 0 so they have the travel speed indicated on top = 25 mm/s

    is there a way to export these settings without the need of typing them all? :D

    Yes, I've read http://support.3dverkstan.se/article/23-a-visual-ultimaker-troubleshooting-guide but I couldn't find what I did wrong... :s

    Any tips to help me out?

    Known problems and what is being done about them

    in Buying or selling your UltiMaker

    Hey LonderJan,

    I'm a noob too :-)

    I bought my printer (an Ultimaker 2) 6 weeks ago now. I started as a complete noob, really, I didn't even knew what a gcode or stl file was. I didn't knew there were so many different options to tweak before getting a great print. And last but not least, I wasn't expecting such a steep learning curve with 3D printing in general.

    I've learned A LOT from these guides : http://support.3dverkstan.se/category/31-guides They are all awesome!

    You can forget about the nozzle problems when you buy the Olsson block upgrade for your UM2. This is highly recommended cause you can switch nozzles in no time and you can use a stainless steel for the special filaments from Colorfabb (wood, bronze, copper, carbon, ...)

    http://3dsolex.com/olsson-block I'm a marketeer and I would personally give the Olsson block free with the UM2 so your potential customers can avoid hours of frustrations. But that's just me :)

    And your feeder problems will also be fixed in no time with this print : https://www.youmagine.com/designs/alternative-um2-feeder-version-two

    I started with spider web prints :p

    check here : https://ultimaker.com/en/community/view/16978-what-do-i-do-wrong-s and here https://ultimaker.com/en/community/view/17073-something-went-wrong-again-what-exactly

    But I'm getting there, step by step :)http://www.thingiverse.com/frederiekpascal/makes

    Don't forget the UM community who's here to help you with all your (noob)issues.

    I highly recommend my UM2 to everybody who's asking me about it. :) (I'm addicted to my UM2 :p)

    cheers

    Something went wrong again... what exactly?

    UPDATE : another serious try to print the iron throne.

    A lot better than the first spider's web print though. :D

    Still many small threads I had to remove with a pincet afterwards, but I'm getting there.

    Also, as you can see in the 3rd photo, the plateau did bend at the end of the 45 hours printing, any reasons for this?

    Any other tips to improve my throne a bit more? :)

    Cura 15.10 Open Beta

    in UltiMaker Cura

    Posted

    Hello,

    Tested the new version : Cura-15.09.81-Darwin.dmg 10-Sep-2015 18:15 36M

    Is there a way to reforce calculating the build time of my object? (cause it looks like it's stuck even after changing details about the slicing)

    Also in layer view you don't see the support anymore?

    thnx

    ow OK, my bad :-)

    The default start.gcode is : 

    ;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
;M109 S{print_temperature} ;Uncomment to add your own temperature line
G21        ;metric values
G90        ;absolute positioning
M82        ;set extruder to absolute mode
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
G92 E0                  ;zero the extruded length
G1 F200 E3              ;extrude 3mm of feed stock
G92 E0                  ;zero the extruded length again
G1 F{travel_speed}
;Put printing message on LCD screen
M117 Printing...

    default end.gcode :

    ;End GCode
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 F{travel_speed} ;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
;{profile_string}

    which one should I use? Or do I need adjustments to any of the codes?

    Is the forum dying?

    Hey,

    There seems to be low activity on the forum but the people who are on the board have been quite helpful to me.

    For the people who don't like the layout, don't forget this link where you can adjust your forum settings. :-)

    I got rid of all the forums I didn't need and the big header on top and now it looks clean. :)

    Also they feature to choose how many topics you can see in the first view is awesome. Now I got 10 topics for the popular forums and the default 3 topics for the less populated forums.

    cheers!

    "perfect" start.gcode & end.gcode for Cura 15.04.2 (Mac) for Octoprint

    in UltiMaker Cura

    Posted

    I've been reading this board and several threads about octoprint and reprap.

    It looks like the default end and start code is not the best to use.

    Currently it is :

    start.gcode :

     

    G28G1 X110 Y45 F3000 ; bring extruder to the frontG92 E0 ; zero the extruded lengthG1 Z30 ; lowerG1 E50 F225 ; purge nozzle with 50mm of filamentG1 X80 Y60 F3000 ; move aside of the puddle of primed plasticG92 E0 ; zero the extruded length again

     

    end.gcode :

     

    G28M104 S0 ; turn off heatersM140 S0 ; turn off bedM84 ; disable motors

     

    But that doesn't seem to be the perfect codes to use with Octoprint?

    Anybody who can help me out with tweaking this code to use with my Ultimaker2?

    Thanks in advance ;)
