Cura 2.1 custom printer platform.stl position

Posted · Cura 2.1 custom printer platform.stl position

Hi.

I've set up a custom printer .json file (copied from one of the others) with an .STL model of my platform.

My platform .stl ends up with the bottom corner located at the centre position of the chequered print area.

I've tried tweaking

'machine_platform_offset'

machine_center_is_zero

machine_width/depth/height

in my new .json and fdmprinter.json (which is inherited) also

I restarted Cura everytime. Nothing seems to change -either the position of the .stl or the shape of the print area.

Does anyone have any tips for this?

(I did search but didn't find anything)

Thanks

(I do like the 2.1 - plenty of knobs and switches!)

    machine_platform_offset -> Offset of the 3D model with regards to the build area (usefull if the center of the build plate model isn't the same as the center of the build area

    machine_center_is_zero -> Is the center of the machine the origin (0,0) coordinate? Some machines see the center as origin. Ultimaker2 for instance sees the left front corner as origin.

    machine_width/depth/height -> Actual width / depth / height of the machine. This is what draws the build volume cube.

    The origin of your platform.stl should be in the center (at least in x and y) and not at the upper left corner ...

    Hi.

    Thanks for the replies.

    I'm still struggling . . .

    I was going to write this:

    nallath

    Changing machine_width/ depth to something obviously odd e.g. 1300 x 50 or as an equal cube it doesn't change the appearance of the build volume cube. I tried it in my new created .json and also fdmprinter.json.

    Same with the offset, it doesn't move the platform.stl

    I tried reboots and restarts just in case.

    It always inserts the correct .STL I created for the platform, as I've changed it a couple of times.

    (So nothing so dumb as I'm editing the wrong files or something!)

    Thanks berndjm

    That seems good advice but how do I change the origin in the .STL?

    I've drawn it in 2 different CAD programs with the origin as centre top (it was front corner) it doesn't change the position.

    . . . but

    I came to the conclusion that my changes were't taking effect.

    I tried creating a new machine .json but it didn't show up in the list of printers.

    I decided to delete/ reinstall cura and delete my configs. And now I can't seem to add a new printer.

    Umm.

    So I'll have to poke around and get back to you.

    Thanks again

    a

    Hi.

    I've got it now.

    I can't say what it was though. Odd but it wasn't updating any changes.

    I started from scratch again.

    machine_platform_offset and machine_width/depth/height did what it should.

    Regards
