README.md problem, and "make cut" problem (_laserscad_temp/<>.echo not found) #16

Closed krbeesley closed 4 years ago

krbeesley commented 4 years ago

I installed v0.3.0 on OS X.

I created an .scad file, including a call to lengrave, that by itself seems to work as expected in OpenSCAD itself.

I then cd’ed to the dist/ directory and found the following instructions in the laserscad README.md, which appear to be in error:

    Under “Lasercutting template”
    the instructions say to “Open a shell and run:”
            cd laserscad/dist
            make engrave model=path/to/your/model.scad

    Then under “Engravings”, it tells you to invoke the very same commands.

From other clues, it would appear that the first command should be 

            make cut model=path/to/your/model.scad

But when I run that, I get

$ make cut model=/Users/beesley/perso/shop/3D/openscad/projects/pads/pads.scad Getting object bounding boxes... Traceback (most recent call last): File "util/extract_bounding_boxes.py", line 86, in extract(*sys.argv[1:]) File "util/extract_bounding_boxes.py", line 26, in extract with open(src, 'r') as file: FileNotFoundError: [Errno 2] No such file or directory: '/Users/beesley/perso/shop/3D/openscad/projects/pads/_laserscad_temp/pads.echo' make: *** [/Users/beesley/perso/shop/3D/openscad/projects/pads/_laserscad_temp/pads_bb.csv] Error 1

In the directory where my pads.scad is located, I see that a directory _laserscad_temp/ was created, but it’s empty.

I continue to look into this, but I’m currently stuck.

Any suggestions?

Hi krbeesley,

sorry for taking so long to respond.

Correct. This is fixed now in the readme.

In the directory where my pads.scad is located, I see that a directory _laserscad_temp/ was created, but it’s empty.

Looks like the very first openscad in the makefile fails. I don't have a device with OS X available so -- could you please try the following things on your end and post the outcome here?

In a shell, what does which openscad return? On my system, it returns

/Users/beesley/bin/openscad

Where ~/bin/openscad is a file containing the following:

!/bin/bash

open -a OpenScad

In OS X, “open -a” opens an OS X application stored in the standard /Applications directory. When you download an OS X app, you put it in /Applications

In a shell, when you cd into the directory with your .scad file and run openscad -D _laserscad_mode=1 -o out.echo pads.scad, does this create the file out.echo in the same directory?

It tells me that -D is not a valid option. Here’s the full complaint:

beesley$ openscad -D _laserscad_mode=1 -o out.echo pads.scad open: invalid option -- D Usage: open [-e] [-t] [-f] [-W] [-R] [-n] [-g] [-h] [-s ][-b ] [-a ] [filenames] [--args arguments] Help: Open opens files from a shell. By default, opens each file using the default application for that file.

Otherwise the highest versioned SDK in each platform is used.

Thanks for looking into this.

Okay, that would explain it.

The wikibooks user manual recommends to use a symlink for OS X which should solve the issue. I will add a note to the readme for the future. Let me know if this fixed your issue. :blush:

I created the symlink, restarted the machine, and ran

$ openscad -D _laserscad_mode=1 -o out.echo pads.scad

And I still get the message:

What is -D supposed to do in your operating system? Perhaps there’s an equivalent for open -D in OS X.

Best wishes,

Ken

The problem seems to be that your previous /Users/beesley/bin/openscad still takes priority over the one in /usr/local/bin/openscad. You might have to remove the former to make it work.

No. I already had renamed it /Users/beesley/bin/openscad.sav

$ which openscad

returns /usr/local/bin/openscad

which is a pointer to /Applications/OpenSCAD.app/Contents/MacOS/OpenSCAD

As far as I can tell, somehow the version of OpenSCAD that I have invokes the “open” command on OS X, and that “open” command on OS X does not recognize the option -D

$ man open

on OS X shows these options:

NAME open -- open files and directories

SYNOPSIS open [-e] [-t] [-f] [-F] [-W] [-R] [-n] [-g] [-j] [-h] [-s sdk] [-b bundle_identifier] [-a application] file ... [--args arg1 …]

No -D. What is the -D supposed to do? There may be an equivalent for the “open” on OS X.

Best wishes,

Ken

-D is a command line option of openscad which should work regardless of the operating system. A similar command which should "just work" would be openscad -v to show the currently installed OpenSCAD version.

To me, it still looks like OpenSCAD is not correctly set up on your machine yet. I can't reproduce it unfortunately and I'm out of ideas at this point. It might be that other users in the OpenSCAD forums or on IRC can help, see https://www.openscad.org/community.html .

Seeing that you posted issue #17 , this here looks like it's resolved.
