Cannot slice with Cura 5.x - missing fdmextruder.def.json file. #1

Steps to reproduce:

Use this Dockerfile:

CMD print3r

Run this:

$ docker run --rm -it -v /Volumes/gv0/workspace/3d-printing/print3r:/root/.config/print3r -e PRINT3R_PRINTER=feestfabriek $(docker build -q .) print3r --slicer=cura-slicer --retraction-speed=50 --retraction-distance=0.2 --layer-height=0.2 --scad slice "cube(20)"

I see that the fdmextruder file is commented out here (and has been for several years). So how is this supposed to work? Am I supposed to install that file myself or something?

Spiritdude commented 1 year ago

You can ignore the fdmextruder.def.json error message as far I know, but any [error] afterwards you need to take care of, e.g. material_shrinkage_percentage_z add into settings/slicers/cura-slicer/base.ini - you have to start CuraEngine / cura-slicer multiple times as more errors will be listed (one at time, unfortunately - this is how CuraEngine works).

I'm behind supporting CuraEngine in print3r since 5.x as I try to empower cura-slicer (Cura-CLI-Wrapper) - which you use in your example - to handle this better, e.g. supporting multiple versions (3.x, 4.x and 5.x each with their correct/respective fdmprinter.def.json).

Btw, your error actually originates in cura-slicer and isn't really about print3r as you set --slicer=cura-slicer, I used to support CuraEngine 3.0 as --slicer=cura and 4.x as --slicer=cura4 but not sure yet to go this way as fdmprinter.def.json changes at each minor [34].{minor} - it has been messy.

I haven't updated cura-slicer on github but I'm currently try to cover 3.x, 4.x and 5.x - but it's a pain to build the older binaries, even 5.0 and 5.1 are hard on Ubuntu-22.04, and yes, Docker might help here (e.g. building 5.0 and 5.1 on Ubuntu-20.04 worked somehow I recall).

Here the current state with building CuraEngine on Ubuntu 22.04:

Spiritdude commented 1 year ago

The CuraEngine 4.13 in default repo of Ubuntu 22.04 I did not get to actually slice anything with cura-slicer, this is why I started to build the binaries now again.

werdnum commented 1 year ago

Thanks for getting back to me so quickly! I had similar experiences building CuraEngine (e.g.).

I tried both --slicer=cura and --slicer=cura-slicer. When I used cura-slicer, I got a very strange output:

Look at the next [error] as I wrote, e.g. now the "next" error shows up: Trying to retrieve setting with no value given: roofing_monotonic - you need to define it, and repeat calling print3r/cura-slicer looking for all the missing defaults, after defaults are defined, it will go through eventually (it depends on the exact version of fdmprinter.def.json).

Spiritdude commented 1 year ago

And yes, stdout of CuraEngine ends up in .gcode, debug setup with cura-slicer first before using print3r.

werdnum commented 1 year ago

I'm a bit confused about why the settings need to be defined, aren't they included already in the fdmprinter.def.json file? Should I just update that file?

Otherwise, should I fill in all those settings and then send a PR to fix it up?

Spiritdude commented 1 year ago

Not just update (try that first), but try to keep CuraEngine and fdmprinter.def.json in sync - this is exactly what I talked about earlier, to properly support different versions.

Usually the problem comes from fdmprinter.def.json and CuraEngine are not in sync covering the same functionality, but I ended up filling settings even when the CuraEngine and fdmprinter.def.json were supposed in sync => Cura (GUI) provides settings which were missing to be set in fdmprinter.def.json is my suspicion.

Don't compose a PR yet, please read again my longer first reply, I haven't decided yet where I cover CuraEngine 5.x support, whether in Print3r direct or via cura-slicer, and if I support it, I want it to do it granular.

Until then I properly support it, proceed as I suggested and add the settings in your install.

werdnum commented 1 year ago

Surprisingly, roofing_monotonic was the only setting that needed adding to slicer/cura-slicer/base.ini - after that I got something that looked like reasonable gcode, though I didn't try printing it yet. Still have to shift all my printer specific stuff into the ini files before I can try that.

Spiritdude commented 1 year ago

I decided to support CuraEngine-5.x via --slicer=cura5, see https://github.com/Spiritdude/Print3r/commit/b868323d9fafeb3ce81af93f59bb72a2677474d4
