Hi trying to make some changes to the mendel90 as of right now just
changed (added MDF16 (5/8') and I want to change the size of the
boards later i.e. the width and height but as of right now  this is
the error I get thinking I need to do some python setting up for this
to work that I am missing anyone here can help ? Like calling Nop and
others to chime in please the error from cmd prompt is below.

I didn't catch much of what you said, but the python stack states that it
cannot launch openscad because it cannot find the executable "openscad".
I don't know how it works on Windows (not used for more than a decade), but
perhaps there is not such exe in your path, or it is not named this way
(are not executable ended with .exe on this platform ?)
