px to inch. I just created my first part for CNC, using openscad, been using it for 3d printing for a long time. To get accurage parts using a openscad->svg->jscut->chillipeppr I found I needed to set a px to inch in jscut to a magic number of 26.74 which is a very different value. Is this settable somewhere in openscad? https://github.com/glennswest/metalcar.git CNC Workflow: Create part in openscad - Finish with a projection, and export to svg open JScut in your web browser (http://jscut.org) Setup your tool sizes (I use a 1mm bit) Setup your PX to Inch to 26.74 Setup how thick you want to cut (6mm for dibond for me) Select the object Generate a outside cut Save to ChilliPeppr via gdrive Switch to http://chilipeppr.com/tinyg Load the gcode using the jscut via gdrive Preview to make sure it looks right Start Cutting On Sun, Oct 25, 2015 at 8:47 AM, MichaelAtOz <oz.at.michael@gmail.com> wrote: > Hi, welcome to the forum. > > You need to complete the mailing list registration too, here. > <http://forum.openscad.org/mailing_list/MailingListOptions.jtp?forum=1> > > Re your issue, have you tried the Dev snapshot binaries > <http://www.openscad.org/downloads.html#snapshots> ? > > > > > > ----- > Newly minted Admin - PM me if you need anything, or if I've done something > stupid... > > Unless specifically shown otherwise above, my contribution is in the > Public Domain; to the extent possible under law, I have waived all > copyright and related or neighbouring rights to this work.

I export DXF from OpenScad and use PyCam to make gcode tool paths. It all works in mm, so no conversion factors needed.
