    Cura 14.03 Slicing does not complete normally

    in UltiMaker Cura

    Posted

    Hi

    Slicing a model (Windows 7) the processing bar goes solid white and stay there. No job time or material used or opportunity to save to SD.

    Using 14.01 on the same PC the job time and material used displays work as expected.

    14.03 has not hung up because if you change a parameter it reslices but still just ends up showing a solid white progress bar

    Where is plugin location In Ubuntu

    in UltiMaker Cura

    Posted

    Hi

    I want to add some plugins to my ubuntu version of cura.

    There is one default plugin "pause at height".

    When I click "open plugin location" I get Could not find "/home/ian/.cura/plugins".

    I created this folder and added a test.py file but it did not show in plugins. Where should plugins go ?

    Regards

    Altering bed temperature

    in UltiMaker Cura

    Posted

    Many thanks

    Unfortunately TweakAtZ works incorrectly in cura version 13.10 RC1. It puts in a bed temperature change line but in the wrong place in the code. I guess Daid has changed something and the plugin would have to be changed to work with the latest version which I understand is coming out of beta any day now.

    Edit

    False alarm. TweakAtZ does work. Unfortunately I have a Z5.0 value in my start gcode file and that triggered TweakAtZ. So long as I don't use Z5.0 as the TweakAtZ value it seems OK.

    Many thanks Jeremie

    I can now see an error. The update/upgrade did not solve the problem, error remains the same.

    ian@ian-desktop:/usr/bin$ cura

    Traceback (most recent call last):

    One for Daid I guess.

    I don't want to upgrade Ubuntu as I have linuxCNC on the same computer and they don't support 12.04 yet.

    Hi

    I started with a ballscrew repstrap. One of the biggest troubles I had was ball screw inertia. I could not get the acceleration or speed you need for 3D printing. It is the low inertia required to move the Ultimaker extruder head that makes it a much better machine than a mendel. I have built a Repstrap, Mendel & finally purchased an Ultimaker. It is streets ahead in speed and therefore resolution. (At low speeds high resolution is like watching paint dry!)

    Forcing walls round adjacent objects.

    in UltiMaker Cura

    Hi

    I wondered if this is possible.

    I am producing fairly large boxes. I have found even with PLA it helps to have 2mm high flat extensions on the corners of the boxes to stop warping. These are then cut off. I am using thin walls and low density fill. This means where the extensions are cut off I am exposing the fill. Is there a way of forcing the wall perimeter to go round the object and treat the extension as a separate object. I have tried making the extension a separate part but If I place it as close as I need to Cura treats as all one object. If I move it away so that Cura does treat it as a separate object with its own wall it ends up too far away to stick to the main object. Is there any way round this?

    PLA Stringing/blobbing

    in UltiMaker Cura

    Posted

    Hi

    I am into my 3rd month of using an Ultimaker with ulticontroller for part production using PLA. I use Cura to great effect and on what I would describe as basic solid parts where the extruder remains with in the body of the object the results are excellent. However recently I have made a number of parts with projecting features (think of a table upside down on the bed with legs in the air). The issue is a lot of stringing and blobs where the extruder stops to move in air across to the next feature. Any suggestions as to the best strategy/settings to reduce this blobbing and stringing? The parts are perfectly usable and clean up with a knife but that is time consuming and I would like if possible to replicate the really clean finish I have achieved on other more basic parts.
