Which post processor
« on: November 10, 2012, 10:47:50 AM »
I have a DIY CNC machine I built from "Build your own CNC machine", I have Vcarve Pro 6.5 and I use Mach 3. My question is which Mach 3 post processor should I use from the list offered in Vcarve? I have just been using the G code which is a .tap file. It works but my engraving is a little off and I am thinking it's cause I am not using the right post processor.  Thanks for any help.

It's unlikely that the post is your problem, but you should be using one of the Mach2_3 ... posts. Usually the ATC posts, if you want to do tool changes.

You always want to use the arc posts.
Use the ATC posts if you're using more than one tool in your g-code. The ATC posts add a toolchange command for mach3 to stop so you can change tools.

thanks. so far i have not figured out how to save more than one tool path at a time. does saving my tool path as an ATC automatically save all the tool paths i have generated?

Yes, but you need to select them all, and check the box that says "Output all visible toolpaths to one file"
