    Help needed printing with PLA+PVA

    in Improve your 3D prints

    Posted

    Hi Cosmin,

     

    thanks for clarification. The prime blob should solve this issue too, as it helps to prime each extruder used. If you use a brim or even a skirt, these extra lines also help priming the nozzle before starting the "real" print.

    The priming behaviour seems to have changed a bit in the last Cura versions.

     

    Regards

    Help needed printing with PLA+PVA

    in Improve your 3D prints

    Hi Cosmin,

     

    if I understood you correct, the PVA is not extruded from extruder 2 when it should be (you wrote PLA is not extruded in dual extrude mode)?

    This sounds like the PVA is retracted to much at the beginning of the print.

    You could try to activate the "prime blob" and the "prime tower" in Cura.

    Material costing Plugin ?

    in UltiMaker Cura

    Posted

    Hi,

     

    in the material-settings for each material, there are two entries for material cost and spool weight, which have to be filled for EACH material you are using. Cura then tells the length of filament on the specified spool and the cost per meter.

    With these parameters set, the costing is displayed  under the estimated print time.

    Continued printing issues

    Hi, hughwyeth,

     

    taking apart the original lever is no big thing, if done carefully.

    At first, the cross-shaped clamp at the "lever"-side should gently be disconnected (be careful not to break the tabs!). I used a flat screwdriver blade (the one of a victorinox swiss knive worked best for me) put between the two halves and gently pressed the two opposite tabs with tweezers, just enough for them to disengage the two halves at this point. You should take care to not cant the parts to much. Then the axle (press-fit) of the bearing should be disconnected by using a flat screwdriver between the not-worn side of your photo above and the bearing. The inner part of the axle (at part 1968) should slide off the outer part (at part 1967) where the bearing sits on.

     

    My first attempt was successful while working with care; disassembling the second lever, I broke one of the spring-parts because of insufficient patience...

    I hope the description is understandable and useful, unfortunately I have no pictures for clarification.

     

    Regards

    Ultimaker 2 Spare parts?

    Hi Chris,

     

    the sintered bushing (like every part of the sliding blocks) is the same for UM2, UM3 and S5, regarding to the description of my reseller (igo3d in Germany):

    https://www.igo3d.com/ultimaker-2-sinteredbushing

    perhaps this helps you to find the part at your reseller in GB.

    Hi,

     

    I don't own a S5, only an UM3, but as they are very similar, here my thoughts to your problem:

    it could be play on the axles (see https://ultimaker.com/en/resources/52606-check-for-play-on-the-axles  to check this), bad tention on the belts (short belts or even long belts) or a not correctly calibrated print head.

    The print head calibration at the S5 should work like at the UM3 (see here: https://ultimaker.com/en/resources/50871-check-for-play-on-axles  note: the calibration sticks provided for the UM3 won't fit the S5, as the diameter of the axles of the S5 seem to be bigger).

    For tightening the long belts, there are some good tutorials on youtube, like e.c. this:

    https://www.youtube.com/watch?v=zNLt8S9hjjc

     

    I hope I could help.

     

    Regards

    There won't be any problem if you use an adhesion sheet on the other side. But since the non-tin side provides decent adhesion by itself, perhaps you don't want to hide it underneath an adhesion sheet 🙂

     

    Hi @SandervG,

    did I understand right, that it would be possible to put an adhesion sheet on the tin side and then just decide printing on the glass-side (and adhesion sheet on the heat bed) and vice versa ("dual-use")?

    Phantom tube created in cura PVA dual extrude support

    in Materials & profiles

    Posted

    Hi Gherndo,

    this fancy little tube is called "prime tower" and, as you supposed, is meant to clean the nozzles in dual extrusion prints to prevent unwanted material bits of the wrong material in the print (acting as a kind of "ooze shield").

    It is found (and can be turned off) in the menue point "Dual Extrusion" (third lower point in the picture you posted).

    If you turn it off, it could appear that the nozzles are oozing and contaminating your print with the wrong material at unwanted positions, so do it with caution and on your own risk. Alternatively, you could use the "ooze shield" (this creates a small shell around your print where the oozed material is shaved off) instead of the prime tower, but I think the prime tower needs less material. I always use the prime tower when printing dual extrusion mode. And since Cura 4.1.0, you can activate a special brim for the prime tower (independently from your adhesion settings) to prevent it from tilting when printing high objects.

    Regards

    Auto level issue after firmware upgrade

    in UltiMaker 3D printers

    Posted

    Hi,

    the first thing I could imagine is an incorrect distance between the top of the base plate and the bottom of the heater plate, which should be approximately 14 mm for the auto leveling to work properly.

    There exists a distance tool for easy adjustment:

     

    https://www.youmagine.com/designs/um3-buildplate-distance-tool

     

    Which error-number is the "out of reasonable" attached? Perhaps there is a helpful description and solution on the UM homepage, like for example this:

    https://ultimaker.com/en/resources/47734-difference-between-detected-height-of-both-printcores-exceeds-realistic-values

     

    Does your capacitive sensor work properly (can be checked in the diagnostics menue since last firmware)?

    Currently im on firmware 4.3.97 which is not the system from the img file, it is 1 update trough the printers menu.

    Using this version for printing is not recommended, as it could lead to unstable behaviour and even "bricking" (which would lead to the requirement of the img procedure...).

    I'd suggest, if you find the installation files for the older firmware (there is a topic somewhere in this forum, but I didn't find it at the moment), install the old version, othervice try the update to 5.2.11 by USB. If it doesn't fix your issue, then retry the img procedure and stay at that firmware version till next firmware update is released.

    @CarloK or someone else at Team Ultimaker: would this be a legit solution?

    @Dim3nsioneer is right. 3.3.97 is just a "stepping stone" firmware only created for installing 5.2.11.

    If your firmware reads something below 3.3.96 (threre was a stepping stone for the "buggy" firmware 5.2.8) after img recovery, you have the choice to keep this version (by non-uptating) or to update to latest. If it reads 3.3.97, updating to 5.2.11 is mandatory. Printing with 3.3.9x could lead to the "stuck on 'remove print'" issue, described in some topics of this forum

    I think, Dim3nsioneer means the "unbricking procedure" described in the forum, for example here:

    Preview simulation bar not visible

    in UltiMaker Cura

    Posted

    Hi Andrea,

     

    your question is a bit unclear, perhaps this is the reason noone reacts.

    If I understood you right, you are missing the tool, where one can see how the object will be printed each layer, right?

    At my Cura 4.0, this feature is placed in preview mode, middle of BOTTOM line, direct under the buildplate.

    I hope I understood your question right and could help.

     

    Regards

    Importing useable files

    in Improve your 3D prints

    Unzipped is ok, Cura must find the files then.

    I only can imagine, that the filter (the drop-down-menu right of the filename field, just above the two buttons "open" and "cancel") is set incorrect. It should read "All Supported Types" or "All Files" or the specific file-type you are using (e.g. "STL-File").

    If the files are still not shown, I'm at my wit's end for now. Possibly a scrrenshot could help.
