    Aligning "modify settings" models

    That's what I needed; thanks. Usable -- you do have to readjust the merged position etc. after, but it's usable.
  2. I'm having trouble figuring out how to position/align "modify settings" models. When I import the STLs, Cura distributes them around the build plate as though they are to be individually printed -- normally that's fine, but when one of them is just a mask for where I need greater infill, I have to eyeball it back into position -- particularly tricky if I'm rotating the models before printing. On a closely related note, shouldn't "automatically drop to buildplate" be per-model, or ignored for modify-settings models? Tips&tricks? Thanks.

    Printhead setting not working

    Switch your Ymin and Ymax. For my Simple Metal I have Xmin 49 Ymin 99999 Xmax 55 Ymax 20 And/or don't use one-at-a-time mode.

    Specify auto0.g as the filename for gcode?

    Can't change the extension, though.
  5. I'm getting some weird slicing when using a large nozzle size; irregularities, and in some cases, outright air space. Nozzle is 1.0; layer height is 0.2. Attachment slicer1 shows irregularities in Benchy's smokestack. Slicer2 shows artifacts in the doorway arch; similar artifacts can be found in all the doors and windows. Slicer3 shows Ben (thing:2795629) with even more artifacts, including a set of layers actually completely missing in the smokestack.
  6. Is there a way to duplicate a machine? I've been experimenting with different nozzle widths lately, and my plan was to define a second machine with the alternate nozzle; that way as I evolve the settings for Machine_Nozzle10, they don't muck up the good settings I've developed for Machine_Nozzle4. However, I can't figure out how to easily duplicate Machine_Nozzle4. (Or is there a more Cura-friendly way to approach this?)

    Variable layer height on a print

    Sorry, I did mean Merge, and both Merge and Group are documented here: https://ultimaker.com/en/resources/35686-merging-and-grouping-models Yes, I cut my model in CAD using an offset plane and load the pieces separately; Merge correctly aligns and associates them -- but Layer Height is not independently settable, even using per model settings.

    Variable layer height on a print

    Thanks! Okay: the good news is that I got Group to work as you describe. Don't get why, or what it thinks it's doing, and arranging several multi-part models on the build plate is fiddly, but it magically works. Bad news: Layer height is still not selectable per-model. Are you seeing something different? Or is there a patch?

    Variable layer height on a print

    Okay, so I'm trying to figure out how to do this, step by step. If I have entirely separate STLs, how do I align them properly? There doesn't seem to be a snap-to-grid, if get the top portion floating above the bottom, even if slightly misaligned, and then click "lay flat" it moves to another spot on the build plate... If I export my STL as a single file, even after splitting my "part", Cura seems to take it in as a single part, not as a pair of parts. Same is true whether I put some air between the split or not. Finally, if I manage to get them arranged on the plate -- per-model select settings doesn't include layer height. Help?

    Cura 2.4.0 app crash at launch

    Well, just crashing is a little abrupt, but that aside: why wouldn't it fall back to the software renderer? Or allow bitmap RDP transmission of the local OpenGL render, as happens if I launch Cura before connecting with RDP? (See screenshot below.)
  11. Cura 2.4.0, Windows 10. Event log shows an uncaught c0000005 exception, immediately followed by an uncaught c000041d exception. May be related to attempting to launch Cura from within an RDP session. (At least, that's the only thing I can think of that's different from the last successful invocation.)
  12. In Cura 15 one could add substitutions in the start and end GCode, e.g.: M140 S{print_bed_temperature} ;start heating bedM104 S{print_temperature} ;start heating extruderG1 Z+10 F{travel_speed} ;move Z up This doesn't work, or has changed, in Cura 2. Clues? Thanks.
  13. I'm trying to move from 15.04.6 to 2.x (currently have 2.3 and 2.4 installed); I've been able to print PLA with good results. However, I'm having a terrible time getting my TPU to print with 2.3 or 2.4. Have worked carefully to migrate settings that work very well in 15.04.6, and still getting awful results. Mystified as to what's going wrong, although it looks a little like under-extrusion, but I am frustrated enough to be opening the GCode files and comparing, and that led me to: Why is 2.4 setting temperature 5 degrees higher than specified? (Also, if anybody has hints about why apparently identical 15.04/2.4 profiles are yielding great/horrible results for TPU, that'd be great.))
  14. I'm pretty sure I've seen this mentioned, and people blowing it off as "your video drivers suxx0rs" but it's 100% reproducible for me via RDP, and I don't think RDP should be considered an edge case. To reproduce: Opeate Cura through an RDP session, load more than one distinct object. Note that you will be unable to select alternate objects (e.g. to reposition or transform.)
