    Advise needed with supports

    Are all the surfaces that you don't want supported properly touched by the support blocker block? I don't see it in your screenshots.

     

    Alternatively I can also recommend changing the overhang to an angle (±30-45°), that way you won't need to use support in the first place.

    Thanks for your reply. I realised that I don't have a clue on how support blockers are set up. After watching a video I managed to get it right.

    Thanks very much.

    Hi all and thank you for your help.

    I designed this phone stand and need to print it.

    Left picture: the hole for the charging cable that needs supports.

    Right picture: Support Structure: Normal and Placement: Everywhere.

    When I choose "Touching Buildplate" it generates support for the text as well that has a -1mm reses into the stand.

    I eventually used "Tree Supports" which worked perfect. But is this the only way? I would rather choose to use the first option as it is using less filament.

    I tried to use Support Blockers on the text but cannot get it to work.

     

    I will appreciate your advice.

    Thanks.

    Settings: Dual Extrusion (Sort of solved)

    in UltiMaker Cura

    Posted · Edited by deonholt
    changed text

    I just learned that Tinkercad does not export two parts as two seperate bodies. This is why Cura sees it is one part and not two.

     

    Thanks.

     

    Hi.

    I added a second extruder about two years ago and had the printing setup in Cura. But I used the second extruder more than a year ago, upgrader to newer versions and also installed a bigger hard drive.

    Long story short, I don't have my Cura settings for dual extrusion printing. I googled to see if I can find some YT video but nothing that helps me from scratch.

    I did install a custom printer and added a second extruder and managed to find my old G-code for this.

    What I cannot seem to get right is the profile settings in Cura. I opened an old 2-part test print I still have but now cannot remember how to assign a specific part to a specific extruder and so on.

     

    Can anyone here please point me to a video-tutorial explaining this?

     

    Attached is a screenshot as designed with Tinkercad as well as a screenshot of the preview in Cura. I know this cannot be correct because I don't see the text in the block.

     

    Thanks.

    Auto Temp Tower temperatures imbedded in other prints?

    in UltiMaker Cura

    Posted

    Hi.

     

    Ultimaker Cura 5:2.1

     

    I decided to print Auto Temp Towers for all filaments I currently have. I wanted to make sure I print them at the correct temperature. I only have about 11 rolls.

     

    I downloaded the "Auto Towers" extension and printed a couple but then had to print something else I needed to print.

    I printed with the current filament which was still in after the temp tower. The correct temperature for this is 190C.  I couldn't understand why it was stringing. I checked and the temperature was 230C. I cleared the building plate with Ctrl-N and opened the STL again and printed again. (I have a Duet board and checked as it prints in the browser.) And then, at layer 4 the temperature changed to 230.

    I downloaded the code and searched through it and noticed that the whole script is almost scattered with AutoTowersGenerator code. I realised that although the STL changed, Cure still used the Auto Temp Tower's temperature settings.

    Here is The first piece of code where I realised that Cure didn't clear the Temp settings:

     

    ;LAYER:4
    M104 S230 ; AutoTowersGenerator setting temperature to 230 for first section
    M117 Temp 230 ; AutoTowersGenerator added

     

    I found with regular intervals M104 commands to drop the temperature with 5C.

     

    I know that when doing Auto Temp Towers that I had to remove the script where I manually created script to change the temperature every so many layers.

     

    Please advise if I am doing something wrong or is there a script I need to run to clear the AutoTowersGenerator script from Cura's head?

     

    Thanks.

     

     

    SOLVED: What is wrong with my G-Code: doesn't print

    in UltiMaker Cura

    Posted · Edited by deonholt

    Hi and thank you for your help.

    Currently using PrusaSlicer but have seen some nice tutorials from a couple of Cura users and want to give it a go.

    My setup:

    Ender 5 Pro

    Duet WiFi 2.0 board

    RepRap firmware

     

    Form some reason my prints don't start. It runs through bed & nozzle heating, ABL & prints the line on the left. And then the nozzle goes to the back right corner and switches off the bed and hot end. My suspicion is that it has something to do with my G-Code. I copied and pasted my start & end code from PS and realised I had to change the settings bed & material temperatures.

    I will appreciate your help.

    Thanks.

    Here is my current scarting code:

     

    ; start code

    T0 ; select tool 1
    G28 ; home all
    M104 S{material_print_temperature} ; set extruder temp
    M140 S{material_bed_temperature} ; set bed temp
    M190 S{material_bed_temperature} ; wait for bed temp
    M109 S{material_print_temperature} ; wait for extruder temp
    G29 ; do abl
    ; G29 S1 ; use stored bed mesh
    ; G91
    G1 E0 F10 ; feed 91mm of filament
    G1 E90 F500
    G1 Z5 F5000 ; lift nozzle 5mm
    G1 X4 Y10 F3000
    G1 Z0.28 F240
    G92 E0
    G1 Y190 E15 F1500 ; intro line
    G1 X4 F5000
    G92 E0
    G1 Y10 E15 F1200 ; intro line
    G92 E0

     

    ; end code

    G91 ; change to relative positioning

    G1 E-90 F1000 ; Retract filament 90mm

    G1 Z20 F500 ; lower bed 20mm from current position

    G90 ; change to absolute positioning

    G1 X200 Y200 ; move tool to back right

    M140 S0 ; turn off heatbed

    M104 S0 ; turn off temperature

    ;M107 ; turn off fan

    M84 X Y E ; disable motors

    Creality Ender 5 Pro with Dual Extruders: Printer Profile?

    I can't help with creating a profile.  I did notice you asked where the Printer Settings plugin went.  They are like Quality, Shell, Travel, Speed, etc. and Printer Settings is the last group at the bottom of the settings.  If you have set up your machine as a Dual Extruder then the Dual Extrusion group of settings should be available as well.

    Thanks very much. Appreciate your help. I have downloaded & installed it but cannot find it.

    copy of old post with more info about machine settings:

    =======
    modifying settings for your particular printer
    Some of them you can edit here:
    Machine settings are usually here:  go to left side of screen in PREPARE mode.  Click on your printer, then do "manage printers" then "machine settings", then "extruder 1". 

     

    Alternatively, you can edit them with the printer settings plugin:
    Click "marketplace" in upper right of cura, make sure you are on "plugins", scroll down and alphabetically among the "P"s is "printer settings" plugin.


    Finally you can edit the json file with your printer settings here.  The files are in a "definitions" folder *somewhere* on your computer (no idea how to find this folder on a PC - maybe in c:/program files/ultimaker/??  Here are 10 of the files out of about 106 different printer configuration files.  Find your printer.
      

    
geo@geo-Wild-Dog-Pro:~/cura/share/cura/resources/definitions$ grep -R -i material_diameter *

builder_premium_small.def.json:        "material_diameter": { "default_value": 1.75 },

     

    I am looking for a Ender 5 Profile with Dual Extrusion. I downloaded & installed the "Printer Settings Plugin" but could not find anything about it on my machine. It says installed when I click on the Marketplace button under Installed.

     

    Please advise what I am missing. Thanks.

     

    Adding Extruders to an existing profile

    You have to edit the machine definition. Or rather create a new one; Cura usually doesn't like messing around with existing machine profiles.

    Thanks. I had to choose another printer which by default has 2 extruders. But, now it doesn't want to import my "old" profiles. I get the error s per attachment.

    Under "Dual Extrusion" click on the "invisible" gear icon.  It's just to the left of the down arrow on the Dual Extrusion bar.  Ticking a setting will make it visible in the main settings window.

     

    in the Machine Settings for your printer, you need to tell Cura how many extruders there are.  The other setting (Extruders share heater) doesn't tell Cura how many extruders, just that all extruders use Heater 0.

    Thanks again for the reply.

    Yes, did click the gear and checked all for the different settings.

    In my printer's (Ender 5 Pro) machine settings, it does not allow me to change the "Number of Extruders" from 1 to 2. It is a dropdown list and does not contain 2.

    I think I am stuck and need to choose another printer with 2 extruders ,,, hope not.

    Everything runs in streaks and this topic has come up a lot lately.

    If you haven't done so already - go to the Marketplace and install the "Printer Settings" plugin.  Restart Cura.  Make the Printer Settings visible and then check the "Extruders Share Heater" box.

    Is this the only place I tell Cura that I have 2 extruders? From what I have understood, it is possible to adjust the settings of the Prime Tower but I cannot find it. I only managed to find "Prime Tower Flow" but nothing more. (4.8.0 beta)

    I don't find these settings:

    Hello all and thank you so long for your help & advice.

    Cura 4.8 Beta

    I get my upgraded printer later today. Upgrades involves moving to a 2-in-1-out configuration. I have absolutely NO experience in printing with dual extruders.

    Can you please advise on what settings I need to change. I had a look at the printer settings and when I hover over "Number of Extruders", the pop-up says: "... An extruder train is the combination of a feeder, bowden tube, and nozzle". What makes me doubt if I should change the number of extruders from 1 to 2, is the fact that I only have 1 nozzle but 2 extruders. My logic says I need to change it to 2, but I just want to confirm.

    What other settings do I need to change or add?

    Any tips will also be very welcome.😉

    Thanks very much.

    How to split part in Cura 4.7.1?

    in UltiMaker Cura

    Posted · Edited by deonholt

    I need to print only part of something. I need to test a specific area for ghosting. It seems that it was possible with earlier version. I know that PrusaSlicer does an excellent job with the click of a button but I have Cura sort of dialed in for what I need to print and don't want to move to Prusa. I like Cura a lot.

    I installed the Mesh extension but when I want to split, it tells me that I cannot split it.
    I need to print only the upper part of the object.
    How do you split a part in Cura?

    On the left of the Cura workspace screen is a toolbar.  The bottom tool is "Support Blocker".  Select your model and then select Support Blocker.  Click somewhere on the model to create a block.

    On the lower left there will be a list of the objects on the build plate (oddly enough called the "Object List").  Your new support blocker will be Eraser and additional blocks will be added to the list.  You can make them active by selecting them on the list.

    When you select the Eraser block you can drag it around or type numbers into the Move tool dialog.  You can also scale it separately in all three axis.  When it covers the proper section of your model you can also elect to have different settings for the intersection volume between your model and the blocker (it's under "Per Model" settings just above the blocker tool).  I found that if I wanted to block support AND infill from an area that I needed two blocks covering the same area with one set to infill and the other set to support.  I haven't played with that aspect of Cura a lot though.

    Thank you very much for a very thorough explanation. Really appreciate your help & time. I got it to work.

    For those who got here by the same google search:

     

    C:\Users\*YOUR USERNAME*\AppData\Roaming\cura

    Thank you very much.

    My reason for asking is that I cannot find 2 older Cura profiles I imported. When I want to import again, Cura says that it is already there and save them as name(1). But, I cannot find them when I look for them under "Profiles".

    Can it be that v4.x doesn't "read" v3.x?
