    jerky speed problem

    in UltiMaker Cura

    Posted

    ... the better stepper chips gives automatic interpolation for slow movements increasing the quality overall, specially on areas where max jerk speed limits the speed...

    Hi @neotko, can you explain this a bit more? What's that "automatic interpolation" the stepper driver is doing? Some links to more information about this?

    CuraEngine command line: use Cura profiles instead of "-s" options?

    Protip; use the CuraContainerRegistry. It does a bit more magic. If you ask the value from a stack that is returned there, it should also handle the resolve. Should be a simple as switching out the ContainerRegistry with the CuraContainerRegistry.

    Updated the script, replaced ContainerRegistry with CuraContainerRegistry.

    @@Nallath: The value for *infill_overlap* is not resolved/evaluated (neither by using ContainerRegistry nor by using CuraContainerRegistry):

    infill_overlap = =10 if infill_sparse_density < 95 and infill_pattern != 'concentric' else 0

    I think this code has to be evaluated somehow before it gets passed over to curaEnginge?

    Any hints?

    Hi,

    i have written a python program cura-engine-wrapper.py that reads the slicing parameters from Cura machine and quality/material profiles and calls CuraEngine with them to slice a model (stl file).

    You can overwrite specific profile parameters on the command line and there are some additional use cases like listing available Cura containers/profiles or dumping the parameters of a given profile.

    You can find it here: http://github.com/ErwinRieger/ddprint/tree/master/scripts.

    More information here: http://ibrieger.de/cura-engine-wrapperpy-helper-to-call-curaengine-from-command-line.html.

    The logs output them when a slice starts. You can just copy them from there.

     

    Of course i can copy it from cura.log... But i am looking for a more integrated/elegant way, something that is more 'single source'.

    Problem is, for example, if i change the machine/profile in cura, i have to remember all places (scripts, Makefiles) where this profile is used (hardcoded settings) and have to update them by hand... This is duplicated and error-prone work.

    I would like to avoid such hardcoded settings and instead reference the cura profiles at theese places.

    Hi,

    i'm working with Cura (2.3.1) under linux. I have created a custom UM2 machine profile and some material/quality profiles.

    Slicing with the Cura GUI is going well.

    Now i want to atomate things, i.e. i want to use CuraEngine (from a Makefile) to slice my STL files into gcode.

    To do this i would have to use many "-s" commandline options to specify the non-default slicer options (a look into cura.log reveals that it is calling CuraEngine with about 330 "-s" options, for example).

    Now the question is:

    Is it possible to use the Cura(-GUI) generated profiles (.cfg files stored in HOME/.local/share/cura) instead of listing them one by one on the CuraEngine command line? It seems that there is no commandline option to specify Cura profiles :-(

    Or is there some other way like generating a list of "-s" options from the Cura profiles?

    (It contains "opinicus", "griffin-display", "jedi-marlin" as main components for example. I could go into the overall architecture in a different post)

    I assume that "jedi-marlin" is the firmware that is running on the "atmega board" (jedi.hex).

    The name suggests that it is Marlin based. If so, where ist the source code?

    the original UM2 feeder can easily reach 15³mm/s with a 0.4mm nozzle
    - Are you kidding?

    Please show me pictures/videos of such a 15mm³/s with 0.4 nozzle print and/or its results...

    To the original question:

     

    • I want to see pictures/videos of such a 24mm³/s print and/or its results.
    • I want more information about the used model and parameters to be able to repeat this test.

    Based on this we did the extrusion stress test (something like this) and we reached 24³mm/s with a .8mm nozzle.

     

    @SandervG

    So i want to repeat this stress test with my printer, can you share some more information on this test and its results?

    * Can you share the model (gcode and STL file)? Some info's about settings (layer height, speed, temps and so on)?

    * Pictures or even a video of the test and it's result?
