OBJ Toolpath Export Missing Ironing #13183
Comments
It turns out the ironing paths are in the obj, but they're half a layer height too low. If you increase ironing spacing to 0.5mm, you'll see where they are because they don't merge into a confusing single layer that's hard to recognize - they're separate lines that you can see between the main extrusions: |
awesome thank you! Is there a way to generate the toolpath OBJ from the
CLI?

Here's a comparison of where they're shown in the slicer and where they
appear in the obj:

And the project file and obj shown there:

I used layer heights 0.15 and 0.3 to test whether the half height
difference is consistent.

(I'm just another user) there's an open issue indicating that you can't get paths out via the CLI, but I haven't tried it #5076 |
I'm trying to use blender to render the OBJ in a script. No matter what I do, line spacing, setting iron flow to 100%, the ironing lines don't seem to show up. Attached render where the ironing flow is set to 100%. It's very visible in the gcode viewer. And I can see the ironing lines when I import it into Fusion. But they get lost in Blender. |
Oh, bespoke product preview? Nice. I would expect prusa to enjoy a valuable application for the export function. |
Yes, it's something like that! :) https://auntlosupplyco.etsy.com |
Good stuff. If you put together a pipeline for fixing the ironing location, you could post it to printables? |
I didn't didn't actually fix anything My workaround is just print config with very narrow top infill lines! |
Heh, this is the way. |
Description of the bug
Using "Iron Topmost Layer" in the slicer and "Export Toolpaths to OBJ" ironing is never rendered out to the OBJ.
Project file & How to reproduce
Slice a file w/ Ironing on .
File -> Export -> Export toolpaths to OBJ.
RESULT: No ironing on OBJ.
