I just uploaded a new build with a couple of significant changes to http://www.grzsoftware.com/v2dl.php .  First, small bitmaps will no longer be “optimized” for machining.  This optimization was used to reduce machine time and it works well unless you use low-resolution bitmaps.  Now, if you have a bitmap with an edge resolution less than 200, no optimization will be used.

Second, the parallel finish layout has been optimized to greatly speed it up.  Most users will never notice unless they are using very small stepovers.  If this is something you do then then I think you will see a difference.

The added feature in this build is integration with the G-Wizard Feedrate Caluclator.  G-Wizard is a very cool piece of code that does some advanced calculations to determine an RPM and feedrate based on your material and tolerance specs.  You can enable the output in G-Wizard in the “Settings” tab as seen below:

When you do a speed/feed calculation you’ll see a “Copy” button as seen here:

That button will copy the tool parameters to the clipboard in a format that Bob and I worked out.  In the Edit Tool dialog in MeshCAM you will see a new “Paste” button if the clipboard contains data that is in the correct format.

I think this will be a big help for new users who aren’t quite sure what settings to use.  It should also help more advanced users get the most out of their mill without sacrificing accuracy.

If you haven’t seen the CNC Cookbook site then be sure to check it out and try the 30 day demo of G-Wizard.
