GCode is Complicated
G-Wizard Makes it Easy

Why does the material stay the same when I select another alloy in G-Wizard?


I am trying your calculator and am surprised at how wrong I have been on feeds and speeds. I’ve only been doing this for 45 years!

Today, I am cutting P20 steel so under H-13 tool steel I found what I wanted and clicked on it and pressed select but the material window in the calculator still says H-13. Is this right?

After you select the material using the “More” button, the Material drop down will still have the same family, in this case “Steel – Tool (H13)”.  However, below that should be a message with the Hardness of the new material to confirm it’s been selected.
