I recently bought a line-us-tool.
When I opend the app I discovered that there is no possibility to import a drawing (png, pdf, svg or jpg file) to plot with line-us. Actually to work with my own handmade drawings was the reason to buy the tool. I´m very disappointed about that fact.
I´m not a developer or engineer, but I want to use line-us as a plotter. I like the idea and the small size of the line-us.
In the forum I read there is a chance to plot a via Inkscape. So I copied the extension files into the directory listed at Edit; Preferences; System: User extensions and restart. I opend LineUsTestDrawing.svg file. Then I opend Extensions; Export; Plot… (There is no special selection, like „plotter line-us").
I get always the following information:
„Inkscape has received additional data from the script executed. The script did not return an error, but this may indicate the results will not be as expected.“
„Traceback (most recent call last):
File "plotter.py", line 268, in <module>
File "inkex.py", line 283, in affect
File "plotter.py", line 98, in effect
File "plotter.py", line 199, in sendHpglToSerial
if ‘ould not open port’ in inst.strerror:
TypeError: argument of type ‘NoneType’ is not iterable“
I have no idea, what this means.
Hope you can give me advise.
All the best Karl
