    Cura 2.3.1 Infill patterns

    in UltiMaker Cura

    Posted

    I see the various ones and a little bit on the mouse over info....but I am having troubles with strength with nGen filament. One of my friends suggested a honeycomb type pattern, but we do not have that option (yet?). Which of the ones available would work better? Cura keeps picking Lines by default but I haven't found any documentation here that states the Pros and Cons of each

    Edit start/stop G-code on UM3 and Cura 2.3

    in UltiMaker Cura

    I didn't see in Cura 2.3.1 where you can make any Start gcode as you could the old Cura

    In my case, for my UMO, I like to extrude 15 mm of filament before the print begins.

    What I do now is open the saved gcode with Notepad (assuming you use Windows) and manually edit the line, then save it. It's an extra step that's a little annoying, but works

    Filiment all tied up

    I feel your pain!

    I had a roll of Ultimaker Silver PLA (newer stuff) do the exact some thing. It was bound up bad inside the roll a few layers.

    Overnight I had a roll of Colorfabb nGen filament do the exact same thing. I have filament guides that seem to help gently unfurl some snags. However this one was inside the roll and tore off the filament guides !

    In the nGen case, I had to unfurl a couple feet of tangles and clip them off.

    And in moth instances these were new rolls that had only done 2 or 3 small (4 hour) prints. So not the beginning of the roll but a few feet into them.

    Hi @gr5 and the gang

    As the others pointed out...I don't think it's me.  

    Here's my file I have to import everytime I power up to use Colorfabb nGen  (I find these settings work great, reducing the 'hairy' prints significantly)

    I can't figure out a way to attach the txt file asides cutting/pasting it in here

    UM3 good quality but poor quality control

    in UltiMaker 3D printers

    Posted · Edited by Guest

    I can also attest to the UM3 QC issues listed here. The over-tightening of the screws causing the notches in the frame to crush is just unacceptable for what Ultimaker is touting as a pro machine.

    If you're in the USA, talk to your reseller or the Fabrc8 people who assemble them here in the 'States.  Erin and Simon are superb to work with. Let me tag Erin @fbrc8-erin

    Best Support Settings in Cura for Ease of Removing?

    in UltiMaker Cura

    Posted

    The zig zag support is a bit problematic for me, since I am printing medium to large size pieces that are curved. To reduce print time, I have oriented them vertically but still run into issues where the head nudges into the supports. Z hop helps some.

    I've never really understood the differences between the support types offered in Cura. The info on the website was absent or vague

    Re-doing the model isn't really an option for me.

    Printing PVA = Lots of problems...

    Fascinating.  Well @ultiarjan the same symptom is true of the newer formulations of Ultimaker PLA.  If you leave it in the bowden for 8 hours it becomes very brittle!  And it has nothing to do with moisture but has to do with mechanically straightening the filament and holding it in that position for many hours.

    That's interesting that you mention that! I have a few spools of new Ultimaker filament in my UMO and on a few occasions, I have had to open the feeder give it a little shove and close the feeder again to get the filament moving.
