I uninstalled inkscape and all the extensions and i started fresh again. I was using the Standard installation for mac as stated in the webpage but after your post i installed it manually and i advanced a little bit now it seem i am missing something called serialposix
Traceback (most recent call last):
File “wcb.py”, line 37, in <module>
File “/Applications/Inkscape.app/Contents/Resources/share/inkscape/extensions/serial/__init__.py”, line 21, in <module>
from serialposix import *
ModuleNotFoundError: No module named ‘serialposix’
Should i install also the axidraw extension?November 24, 2020 at 1:25 pm #28781Windell OskayKeymaster
Is the AxiDraw software working?November 24, 2020 at 1:48 pm #28783
Yes, axidraw extension is working without a problem but the watercolor bot is giving me the serialposix problem in osx.
I tried in Linux and i got a message in the same 37 line but in this case the message was that no module called “serial” was found. As that happened to me before in linux with another module i installed python3-serial and that worked. Now i am researching how to install the serialposix module in osx.
I printed a page in linux and i don’t have the 45 degree problem anymore now my problem is the scale. I changed the DPI number in wcb_conf.py from 2032 to 2874 and i got a bigger drawing but still is too small and also the area of the water and paint got bigger. That is why i think changing the DPI is not the correct approach. Do you know a better way to control the scale of the drawing?November 24, 2020 at 1:50 pm #28784
By the way every time i tried to open the watercolorbot template Inkscape crashes.November 24, 2020 at 2:02 pm #28785Windell OskayKeymaster
On the error: Did you replace wcb.py, or did you put it in the main extensions folder? From the error, it looks like you put it in the main extensions folder, so that it can’t find the dependencies.
I’ve updated the template document with a newer one. I have tested this, and when I draw a 10 cm square, it plots as 10 cm.

Yes, try the template *without* changing the scale values.November 24, 2020 at 2:53 pm #28787
I have just changed the scale of the template in Inkscape to 1,05000 and is perfect i am getting the 10cms nowNovember 26, 2020 at 10:22 am #28786
In osx I replaced the wcb.py installed by the installer (https://github.com/evil-mad/wcb-ink/releases/latest) with the one i downloaded from the github V1 branch in the extension folder (Modified version for printing on AxiDraw) It was the same one that i installed in linux. And wcb.py is located here:/Applications/Inkscape.app/Contents/Resources/share/inkscape/extensions
In osx I also installed them in the user extension folder but it is exactly the same.
Thanks a lot for the new template i still could not open it from linux who knows why but i opened it in osx and there was not a problem. I made a new file with the same size as the template (990x720px scale 1) in Linux and the size of the 10cm cube was very close I got 10.6 cm. Is this small discrepancy because i am missing something from the original template or does it have to do that i have an AxiDraw V3/A3?
