image to g-code problem

Just trying a quick experiment to see if a relatively simple method of producing the shape I want would work using the 'image to g-code' conversion.
however, it threw up the error shown in the screen grab attached. The thumbnail above the error window is the .jpg in question, and is designed to produce a dome with 24 ribs outside.
Any ideas as to getting this to work would be gratefully received.

Perhaps the first question should have been "where do I find the ini file to see if the Filter has the required lines inserted or not.
I thought I had done this successfully before, but so long ago I've forgotten the details !

John

you probably need to

Configuration files will be in /linuxcnc/config/name of your config

Hi dgarrett.
Did that, but no change, still the same error window.

Hi John,
Thanks, so I went there and found the [FILTER] entry as per the manual, so I went back to the actual error window and tried to understand its meaning.
I assume that a "module" is an entry that should be present, but where ?
Should it be in the .ini file, as above, or in .../git/linuxcnc/bin image-to-gcode file ?

Just checked the image-to-gcode file and have copied the portion referred to here

def ui(im, nim, im_name):
import Tkinter
import ImageTk
import pickle
import nf

app = Tkinter.Tk()
rs274.options.install(app)
app.tk.call("source", os.path.join(BASE, "share", "axis", "tcl", "combobox.tcl"))

Hope that helps !

Had brainwave. Took file on stick out to workshop and tried it on a working system rather than the sim axis on the laptop.
It seems to be working. Well, it's taking forever to process, but at least its loading.

20 minutes later it's still loading, so I'll scrub that and try something simpler first !

Tried a simple dome.
That gave the same error window on my sim version, but worked ok in the workshop.
So I saved the gcode onto a stick, and brought it back to the house (warm !) and opened it up in sim axis ok.
Rather than spend time trying to get the sim to work by finding out what the difference is, I'll use this as a method for now.

If anyone could say what I need to do to rectify the problem, I'd still be very grateful.
